Mojo Vision

Mojo Vision, a technology company founded in 2015 and based in Silicon Valley, has announced it is building the world’s first truly “smart” contact lens, called the Mojo Lens.

Mojo Lens is a contact lens with a built-in display that gives people  useful and timely information they want, without forcing them to look down at a screen or losing focus on the people and the world around them. Mojo calls this eyes-up experience Invisible Computing, a platform that enables information to be instantaneous, unobtrusive and available hands-free, and will allow people to interact with each other more freely and genuinely.

The company has been researching and developing its groundbreaking technology and holds patents critical to the development of an augmented reality (AR) smart contact lens dating back over 10 years. Mojo is conducting feasibility clinical studies for R&D iteration purposes under an Institutional Review Board (IRB) approval. The Mojo Lens is under research and development phase is not available for sale anywhere in the world. The company’s product development plans had previously remained in stealth.

The Mojo Lens is designed to be used in many different situations, from consumer to enterprise. Additionally, the company is planning an early application of the product designed to help people struggling with low vision via enhanced image overlays. The Mojo Lens is designed to offer real-time contrast and lighting enhancements, as well as zoom functionality. With its inconspicuous contact lens form factor, Mojo Lens is designed to serve as a low vision aid that could remain discreet for the wearer and allow a hands-free experience, while delivering enhanced functional vision to assist in mobility, reading, and sighting.

In businesses and organisations, the Mojo Lens is being designed to give workers or specialists access to real-time information, greatly improving productivity, precision, and compliance without having to look down at a mobile device or through an awkward, vision-blocking headset that limits situational awareness or discourages social interactions. The Mojo Lens incorporates a number of breakthroughs and proprietary technologies – including the smallest and densest dynamic display ever made, the world’s most power-efficient image sensor optimised for computer vision, a custom wireless radio, and motion sensors for eye-tracking and image stabilisation. The Mojo Lens includes the Mojo Vision 14K PPI Display, announced in May 2019. This delivers a world-record pixel pitch of over 14,000ppi and a pixel density of over 200Mppi², making it the smallest, densest display ever designed for dynamic – or moving – content.

“After extensive research, development, and testing, we are excited to reveal our product plans and begin sharing details about this transformative platform,” said Drew Perkins, CEO at Mojo Vision. “Mojo has a vision for Invisible Computing where you have the information you want when you want it and are not bombarded or distracted by data when you don’t. The technology should be helpful, and it should be available in the moment and fade away when you want to focus on the world around you.”

“The Mojo Lens is the first step in delivering Invisible Computing to the world. We look forward to sharing more information and demonstrating future prototypes as we get closer to bringing our product to market,”

Screenless display :

Screenless display is any system for transmitting visual information from a video source without the use of a screen. Screenless computing systems can be divided into three groups: Visual Image, Retinal Direct, and Synaptic Interface.

Screenless display is an interactive projection technology developed to solve the problems related to the device miniaturization of the modern communication technologies. The lack of space on screen based displays provides an opportunity for the development of screenless displays. As the name indicates screenless display has no screen and it can be defined as a display used to transmit any data such as pictures.

Is that holography and screenless display same ?

Visual Image Display :

The visual image is a type of screenless display, which recognizes any type of image or thing with the help of the human eye.… Holographic displays are commonly used as an alternative to screens. Holographic Display. Heads up display are also named as transparent displays.

Types of Screenless Display :

1.Visual Image Display
2.Retinal Display
3.Synaptic Interface

The first category, visual image is defined as the things that can be seen by the human eye such as holograms. The second category, retinal display – the name itself- indicates the display of image directly onto the retina. The third category , synaptic reference which means sending information directly to the human brain.
Let us look on in detail about these three display types.

Visual Image Display :

The visual image is a type of screenless display, which recognizes any type of image or thing with the help of the human eye. The following are few examples of the visual image display: holographic display, virtual reality goggles, heads up display, etc. The working principle of this display states that the light gets reflected by the intermediate object before reaching the retina or the eye. The intermediate object can be a hologram, Liquid Crystal Displays (LCD)s or even windows.

By using the components like Helium Neon Laser, an object, a Lens, a holographic film and mirror, the Holographic Displays display the three dimensional (3D) images. A 3D image will be projected and appears to be floating in the air whenever the laser and object beams overlaps with each other. This display can supply accurate depth cues and high-quality images and videos that can be viewed by the human eyes without any need of special observation devices. Based on the colors of the laser
projector, images are formed in three distinct planes. Holographic displays are commonly used as an alternative to screens.

Retinal Display :

The second category of advancement in display system, retinal display as the name itself indicates the display of image directly onto the retina. Instead of using some intermediate object for light reflection to project the images, this display directly projects the image onto the retina.The user will sense that the display is moving freely in the space. Retinal display is commonly known as retinal scan display and retinal projector.This display allows short light emission, coherent light
and narrow band color.

Let us know about this display with the help of the following block diagram.

The block diagram of the virtual retinal display consists of following blocks: photon generation, intensity modulation, beam scanning, optical projection and drive electronics. Photon generation block generates the coherent beam of light; this photon source make use of the laser diodes as coherent source with retina display to give a diffraction onto the retina of the human eye. The light generated from photon source is intensity modulated. The intensity of the light beam gets modulated to match the intensity of the image.

Synaptic Interface:

The third category, synaptic interface means sending information directly to the human brain without using any light. This technology is already tested on humans and most of the companies started using this technology for effective communication, education, business and security system. This technology was successfully developed by sampling the video signals from horse crab eyes through their nerves, and the other video signals are sampled from the electronic cameras into the brains of creatures.

The brain computer interface allows direct interaction between the human brain and external devices such as computer.This category can also be known by different names such as human machine interface, synthetic telepathy interface, mind machine interface and direct neural interface.

These are the three types of latest Screenless displays which replace the current use of touch screen technology to fill the lack of space in the screen-based electronic displays.We hope that the future definitely looks promising for this technology. Let us wait for the day when we all will be treated by this technology.

Agricultural robot :

An agricultural robot is a robot deployed for agricultural purposes. The main area of application of robots in agriculture today is at the harvesting stage. Emerging applications of robots or drones in agriculture include weed control, cloud seeding, planting seeds, harvesting, environmental monitoring and soil analysis. According to Verified Market Research, the agricultural robots market is expected to reach $11.58 billion by 2025.

Fruit picking robots, driverless tractor / sprayers, and sheep shearing robots are designed to replace human labor. In most cases, a lot of factors have to be considered (e.g., the size and color of the fruit to be picked) before the commencement of a task.

Robots can be used for other horticultural tasks such as pruning, weeding, spraying and monitoring. Robots can also be used in livestock applications (livestock robotics) such as automatic milking, washing and castrating. Robots like these have many benefits for the agricultural industry, including a higher quality of fresh produce, lower production costs, and a decreased need for manual labor.

Designs :

The mechanical design consists of an end effector, manipulator, and gripper. Several factors must be considered in the design of the manipulator, including the task, economic efficiency, and required motions. The end effector influences the market value of the fruit and the gripper’s design is based on the crop that is being harvested.

1.End effectors :

An end effector in an agricultural robot is the device found at the end of the robotic arm, used for various agricultural operations. Several different kinds of end effectors have been developed. In an agricultural operation involving grapes in Japan, end effectors are used for harvesting, berry-thinning, spraying, and bagging.

2.Gripper :

The gripper is a grasping device that is used for harvesting the target crop. Design of the gripper is based on simplicity, low cost, and effectiveness. Thus, the design usually consists of two mechanical fingers that are able to move in synchrony when performing their task. Specifics of the design depend on the task that is being performed. For example, in a procedure that required plants to be cut for harvesting, the gripper was equipped with a sharp blade.

3.Manipulator :

The manipulator allows the gripper and end effector to navigate through their environment. The manipulator consists of four-bar parallel links that maintain the gripper’s position and height. The manipulator also can utilize one, two, or three pneumatic actuators.

Applications :

Robots have many fields of application in agriculture. Some examples and prototypes of robots include the Merlin Robot Milker , Rosphere , Harvest Automation, Orange Harvester, lettuce bot,and weeder. One case of a large scale use of robots in farming is the milk bot.

It is widespread among British dairy farms because of its efficiency and nonrequirement to move. According to David Gardner (chief executive of the Royal Agricultural Society of England), a robot can complete a complicated task if its repetitive and the robot is allowed to sit in a single place.

Furthermore, robots that work on repetitive tasks (e.g. milking) fulfill their role to a consistent and particular standard.

1.Thorvald – an autonomous modular multi-purpose agricultural robot developed by Saga Robotics.
2.Vinobot and Vinoculer.
3.LSU’s AgBot.
4.Harvest Automation is a company founded by former iRobot employees to develop robots for greenhouses.
5.Root AI has made a tomato-picking robot for use in greenhouses.
6.Strawberry picking robot from Robotic Harvesting and Agrobot.

21.ACFR Digital Farmhand: for spraying, weeding and seeding.

LI – FI :

Li-Fi (short for light fidelity) is wireless communication technology which utilizes light to transmit data and position between devices. The term was first introduced by Harald Haas during a 2011 TEDGlobal talk in Edinburgh.

In technical terms, Li-Fi is a light communication system that is capable of transmitting data at high speeds over the visible light, ultraviolet, and infrared spectrums. In its present state, only LED lamps can be used for the transmission of visible light.

Li-Fi is a derivative of optical wireless communications (OWC) technology, which uses light from light-emitting diodes (LEDs) as a medium to deliver network, mobile, high-speed communication in a similar manner to Wi-Fi. The Li-Fi market was projected to have a compound annual growth rate of 82% from 2013 to 2018 and to be worth over $6 billion per year by 2018.

Visible light communications (VLC) works by switching the current to the LEDs off and on at a very high speed ,too quick to be noticed by the human eye, thus, it does not present any flickering.
Although Li-Fi LEDs would have to be kept on to transmit data, they could be dimmed to below human visibility while still emitting light to carry data.

This is also a major bottleneck of the technology when based on the visible spectrum, as it is restricted to the illumination purpose and not ideally adjusted to a mobile communication purpose. Technologies that allows as roaming between various Li-Fi cells, also known as handover, may allow to seamless transition between Li-Fi.

The light waves cannot penetrate walls which translates to a much shorter range, and a lower hacking potential, relative to Wi-Fi. Direct line of sight is not necessary for Li-Fi to transmit a signal; light reflected off walls can achieve 70 Mbit/s.

Advantage :

Li-Fi has the advantage of being useful in electromagnetic sensitive areas such as in aircraft cabins, hospitals and nuclear power plants without causing electromagnetic interference.
Both Wi-Fi and Li-Fi transmit data over the electromagnetic spectrum, but whereas Wi-Fi utilizes radio waves, Li-Fi uses visible, ultraviolet, and infrared light. While the US Federal Communications Commission has warned of a potential spectrum crisis because Wi-Fi is close to full capacity, Li-Fi has almost no limitations on capacity. The visible light spectrum is 10,000 times larger than the entire radio frequency spectrum.

WI-FI ?:

Wi-Fi is a family of wireless network protocols, based on the IEEE 802.11 family of standards, which are commonly used for local area networking of devices and Internet access.

Light-emitting diode ?:

A light-emitting diode (LED) is a semiconductor light source that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons. The color of the light (corresponding to the energy of the photons) is determined by the energy required for electrons to cross the band gap of the semiconductor.

Visible light communication(VLC) ?:

Visible light communication (VLC) is a data communications variant which uses visible light between 400 and 800 THz (780–375 nm). VLC is a subset of optical wireless communications technologies.

Optical wireless communications ?:

Optical wireless communications (OWC) is a form of optical communication in which unguided visible, infrared (IR), or ultraviolet (UV) light is used to carry a signal.

Space-based solar power :

Space-based solar power (SBSP) is the concept of collecting solar power in outer space and distributing it to Earth. Potential advantages of collecting solar energy in space include a higher collection rate and a longer collection period due to the lack of a diffusing atmosphere, and the possibility of placing a solar collector in an orbiting location where there is no night.

A considerable fraction of incoming solar energy (55–60%) is lost on its way through the Earth’s atmosphere by the effects of reflection and absorption. Space-based solar power systems convert sunlight to microwaves outside the atmosphere, avoiding these losses and the downtime due to the Earth’s rotation, but at great cost due to the expense of launching material into orbit. SBSP is considered a form of sustainable or green energy, renewable energy, and is occasionally considered among climate engineering proposals. It is attractive to those seeking large-scale solutions to anthropogenic climate change or fossil fuel depletion (such as peak oil).

Various SBSP proposals have been researched since the early 1970s, but none are economically viable with present-day space launch infrastructure. Some technologists speculate that this may change in the distant future if an off-world industrial base were to be developed that could manufacture solar power satellites out of asteroids or lunar material, or if radical new space launch technologies other than rocketry should become available in the future.

SBSP is being actively pursued by Japan, China, Russia, and the US. In 2008, Japan passed its Basic Space Law which established space solar power as a national goal and JAXA has a roadmap to commercial SBSP. In 2015, the China Academy for Space Technology (CAST) showcased their roadmap at the International Space Development Conference. In May 2020 the US Naval Research Laboratory conducted its first test of solar power generation in a satellite.

Advantages and Disadvantages :

Advantages :

The SBSP concept is attractive because space has several major advantages over the Earth’s surface for the collection of solar power:

  1. It is always solar noon in space and full sun.
  2. Reduced plant and wildlife interference.
  3. Power could be relatively quickly redirected directly to areas that need it most.

Disadvantages :

The SBSP concept also has a number of problems:

  1. The large cost of launching a satellite into space.
  2. Microwave optic requires GW scale due to Airy disk beam spreading.
  3. Typically a 1 km transmitting disk at 2.45 GHz spreads out to 10 km at Earth distance.
  4. Inaccessibility.

Drone Display :

A drone display is the use of multiple unmanned aerial vehicles (drones), often quadcopters, flying in a coordinated fashion for public display. They are usually equipped with LEDs, and the display held at night. The first Drone Display was presented in 2012 in Linz/Austria, where the Ars Electronica Futurelab introduced Spaxels for the first time. The displays may be for entertainment, where the drones may use flocking or swarming behaviour. The drones may also be coordinated
to produce images. Using this emerging technology, displays have been employed for advertising purposes as well.

Intel has produced the Shooting Star, a type of drone used in light shows. They were used during the 2018 Winter Olympics, a Super Bowl halftime show in 2017, and a 2018 4 July celebration. Drone light shows differ from fireworks displays in that drones are reusable, and do not produce air and noise pollution. However, drone displays cannot take place during rain or strong winds.

What is Quadcopter ?

A quadcopter or quadrotor is a type of helicopter with four rotors. Although quadrotor helicopters and convertiplanes have long been flown experimentally, the configuration remained a curiosity until the arrival of the modern UAV or drone. The small size and low inertia of drones allows use of a particularly simple flight control system, which has greatly increased the practicality of the small quadrotor in this application.

What is Unmanned aerial vehicle ?

An unmanned aerial vehicle (UAV) (or uncrewed aerial vehicle, commonly known as a drone) is an aircraft without a human pilot on board and a type of unmanned vehicle. UAVs are a component of an ground-based controller, and a system of communications between the two; which include a UAV, aground-based controller, and a system of communications between the two.


Holography is the science and practice of making holograms. A hologram is a photographic recording of a light field, rather than an image formed by a lens. A hologram is a real world recording of an interference pattern which uses diffraction to reproduce a 3D light field, resulting in an image which still has the depth, parallax, and other properties of the original scene.

In its pure form, holography needs a laser light for illuminating the subject and for viewing the finished hologram. A microscopic level of detail throughout the recorded scene can be reproduced. In common practice, however, major image quality compromises are made to remove the need for laser illumination to view the hologram, and in some cases, to make it.

How it works ?

Holography is a technique that enables a light field (which is generally the result of a light source scattered off objects) to be recorded and later reconstructed when the original light field is no longer present, due to the absence of the original objects.

Holography can be thought of as somewhat similar to sound recording, whereby a sound field created by vibrating matter like musical instruments or vocal cords, is encoded
in such a way that it can be reproduced later, without the presence of the original vibrating matter. However, it is even more similar to Ambisonic sound recording in which any listening angle of a sound field can be reproduced in the reproduction.


The Hungarian-British physicist Dennis Gabor (in Hungarian: Gábor Dénes)was awarded the Nobel Prize in Physics in 1971 “for his invention and development of the holographic method“. His work, done in the late 1940s, was built on pioneering work in the field of X-ray microscopy by other scientists including Mieczysław Wolfke in 1920 and William Lawrence Bragg in 1939.This discovery was an unexpected result of research into improving electron microscopes at the British Thomson-Houston Company (BTH) in Rugby, England, and the company filed a patent in December 1947 (patent GB685286,you can check the details here).The technique as originally invented is still used in electron microscopy, where it is known as electron holography, but optical holography did not really advance until the development of the laser in 1960. The word holography comes from the Greek words ὅλος (holos; “whole”) and γραφή (graphē; “writing” or “drawing”).


A humanoid robot is a robot with its overall appearance based on that of the human body.

In general humanoid robots have a torso with a head, two arms and two legs, although some forms of humanoid robots may model only part of the body, for example, from the waist up.

A humanoid robot is a robot with its body shape built to resemble the human body. The design may be for functional purposes, such as interacting with human tools and environments, for experimental purposes, such as the study of bipedal locomotion, or for other purposes. In general, humanoid robots have a torso, a head, two arms, and two legs, though some forms of humanoid robots may model only part of the body, for example, from the waist up. Some humanoid robots also have heads designed to replicate human facial features such as eyes and mouths. Androids are humanoid robots built to aesthetically resemble humans.

Humanoid robots are now used as research tools in several scientific areas. Researchers study the human body structure and behavior (biomechanics) to build humanoid robots.


Humanoid robots are professional service robots built to mimic human motion and interaction. Like all service robots, they provide value by automating tasks in a way that leads to cost-savings and productivity. Humanoid robots are a relatively new form of professional service robot.

Advantages of Humanoid Robots

The ability to detect electrical activity in the brain through the scalp, and to control it, will soon transform medicine and change society in profound ways. Patterns of electrical activity in the brain can reveal a person’s cognitionnormal and abnormal. New methods to stimulate specific brain circuits can treat neurological and mental illnesses and control behavior.


The ability to interrogate and manipulate electrical activity in the human brain promises to do for the brain what biochemistry did for the body. When you go to the doctor, a chemical analysis of your blood is used to detect your body’s health and potential disease. Forewarned that your cholesterol level is high, and you are at risk of having a stroke, you can take action to avoid suffering one.

Likewise, in experimental research destined to soon enter medical practice, just a few minutes of monitoring electrical activity in your brain using EEG and other methods can reveal not only neurological illness but also mental conditions like ADHD and schizophrenia. Tapping into your wandering mind can measure your IQ, identify your cognitive strengths and weaknesses, perceive your personality and determine your aptitude for learning specific types of information.

Neuroscientist Marcel Just and colleagues at Carnegie Mellon University are using fMRI brain imaging to decipher what a person is thinking. By using machine learning to analyze complex patterns of activity in a person’s brain when they think of a specific number or object, read a sentence, experience a particular emotion or learn a new type of information, the researchers can read minds and know the person’s specific thoughts and emotions.


The ability to control electrical activity in brain circuits has the potential to do for brain disorders what electrical stimulation has accomplished in treating cardiac disorders. By beaming electrical or magnetic pulses through the scalp, and by implanting electrodes in the brain, researchers and doctors can treat a vast array of neurological and psychiatric disorders, from Parkinson’s disease to chronic depression.

Mind Reading and Mind Control Technologies Are Coming :

Facebook-backed scientists have announced that they can now read human thoughts by analysing signals sent within the brain. … The research is funded by Facebook Reality Labs, which wants to develop a non-invasive brain interface which will allow people to type by simply thinking about what they want to write.
