Road accidents cause large number of deaths, injuries and disabilities of people around the world and it has been found that 10%-20% of fatal road accidents are due to driver’s negligence. Further from the researches it has been identified that main causes for this inattention are drowsiness and distraction.
The aim of RIYADISI is to assist drivers to maintain their attention throughout the journey by monitoring and alerting them throughout the journey. RIYADISI is a real time, automated and noninvasive (not involving the introduction of instruments into the body) system which uses computer vision and machine learning techniques to detect driver drowsiness and distraction and alerts the driver. The main distinguishing feature of RIYADISI when compared with other related products in the market that it does not have any instruments attached to the body of the driver.
The monitoring video camera (Height-2 cm X Width-5 cm approx.) is placed on the dashboard near steering wheel which uploads a live video stream of the driver to a central server. The video stream is analyzed from the central server software and it identifies the status of the driver, whether he is sleepy or not concentrating on driving.
RIYADISI system uses decreased eye blinking rate, yawning and nodding off to detect drowsiness whereas it uses eye-gaze movement and head movements to detect distraction. If the central server detects that the driver is drowsy or distracted, the system has the capability to alert the driver on the same. Furthermore the video camera used here is an Infra-Red (IR) camera which facilitates to use the system in the night as well.
The next phase of this invention is to integrate the whole system into a mobile app where the mobile phone will be able to alert the driver by continuously monitoring him.
RIYADISI is an invention by a team of final year undergraduates of Department of Computer Science and Engineering of University of Moratuwa under the guidance of Dr. Chathura Perera. Team members are Dileepa Fernando, Sandareka Wickramanayake, Sadari jayawardena and Sanka Darshana.
While congratulating the team of inventors on RIYADISI product, we wish them all the best for the next phases of the product and looking forward to see this novel product in the market in near future.

If you can remember Tom Cruise using a 3D holographic system in the film Minority Report back in 2002, you might have thought how cool it would be to have it real life. Well it has arrived!
A 24 year old entrepreneur from Russia has successfully invented such a device which can show interactive display right in the air. Not yet to the clarity of the one in Minority Report, but through this device you can control a screen in midair with almost real time responsiveness. Check it out in the below video
Displair treats the air and disengage the smallest moisture particles, and then add them up again to the refined air. Because of this, the air seems to be kind of pale or bleached. This state is called “fog”, but it is absolutely dry. Also by having the particles very small, they are stable even when they collided with physical objects, thus not leaving any wet traces. When an image is projected on to this air layer, it creates a screen in mid air.
The specific software and the set of sensors (Infrared cameras) make it possible to manipulate the image. Users feel it entirely. All the fingers can be used to control the image. Several people can use it at the same time, simultaneously as well.
There is a 0.2 second lag between the action and the actual motion. Displair can detect smaller finger movements up to 1500 contact points with the accuracy of 1cm. This depends on the screen size which varies between 40 and 140 inches.
The inventor of Displair is Russian Maksim Kamanin, who was a network engineer who ultimately pursued his dreams to create a futuristic device.
“I was working as a network engineer, when we were fastening a motherboard, it seemed so dull, that my friend and I were dreaming about the future and how everything would look like then and this talk somehow caught me and I thought ‘Why not start doing it right now?’
I started to search for the information and data, learning more and more. At last I came up to the effects of mirages, clouds. Once I was in a church, I noticed that the space above the candle was diffluent and at that particular moment I realized that a special physical effect will definitely take place and we’ll be able to create and image right in the air”
Maxim with the help of other people interested in the project were able to develop a working model in their dormitory. He explained how things went on from there when he got a call from Moscow:
“You’ve got and interesting project. If you have a functional prototype, you’ll have a chance to meet the President of the Russian Federation”
Maxim with his Displair project went on to win many of the innovation competitions and prizes in Russia, including the top on “Zvorykin Prize 2011”.
Adrien Henni became one of the first of the foreign partners. He gave Displair the understanding of how to attract investments, how the company should develop at this point. He introduced Maxim to most of the great companies we cooperate with at the moment.
Once they come through in Russia, Displair thinks they have a good chance to expand abroad. They have already got $1M investments from Silicon Valley giants. Pretty soon they will be entering the second round of investments. Once they expand the pilot production, they are planning to increase the company headcount and entering foreign markets. Maxim said “At some point we will become self-supporting”. That’s our goal as a company.
Displair has already taken the path of the patent war. A company called Fogscreen who develop a similar type of screen insist that that Displair should stop doing the development of this project, otherwise they will fight Displair.
The Future of Displair
Work needs to be done on the clarity of the image and also the required fine tuning for it to appeal to consumer masses. However Displair is an amazing innovation and seems that it is well on course to be the next big thing in displays.
Out of the 7 billion people who live on earth, 1.5 billion people are still using alternative biomass fuels (mostly kerosene) to generate light as they have no reliable access to electricity.
Yearly, 2.5 million in India alone suffer from severe burns due to overturned kerosene lamps. In Sri Lanka also there are many burn cases due to kerosene lamps. According to World Bank reports 780 million women and children are vulnerable to inhaling of kerosene smoke which is equivalent to 2 packets of cigarettes a day. Although not seen obvious, kerosene used only for lighting can consume a 10% to 20% of the entire income of a family. With ever rising fuel prices, the overhead expenditure on kerosene has created a burden which keeps them in a permanent state of subsistence living.
What is the Gravity Light?
There are many solutions found for low power off grid energy generation. Solar powered electricity in rural areas is a well-known example. Gravity light is a device that converts potential energy to light by the use of a dynamo. Someone needs to lift the weight (bag full of earth or sand weighing about 10kg) to the top position where from that point onwards the weight will slowly move down with the help of gears that cause the dynamo to rotate longer generating electricity which is transformed to disseminating light through a LED.
It takes only 3 seconds to lift the weight, but it can power up to 30 minutes. There is no recurring costs; No batteries; its fully clean and green energy.
It takes only 3 seconds to lift the weight, but it can power up to 30 minutes. There is no recurring costs; No batteries; its fully clean and green energy. Gravity light illumination strength is better than typical kerosene lamps. Light output is adjustable; depending on what is filled in the weight bag and the brightness of the light, it may light between 18 minutes to 30 minutes. The Dynamo and the LED lights are designed to be very efficient, so that it can last up to long time. Although you can listen to a small radio or charge batteries, you won’t be able to charge your high end phone or do fancy things with that. It’s simple and basic.
LED bulbs do not attract insects like mosquitos which is another plus point. The goal is to build a commercial version for $5. In a typical target household, the initial cost will be covered within first 2-3 months and then onwards it’s an advantage for them. Saving the money burnt as kerosene for lighting.
Who is behind Gravity Light Project?
Therefore is a UK based design company which started the project Deciwatt which is behind the Gravity light. Therefore has vast experience over 20 years in development handheld, communication and computing households for leading companies like Toshiba, NEC, Psion and Tom Tom. London-based designers Martin Riddiford and Jim Reeves of Therefore spent four years developing the light.
Do I need one at home?
I don’t want it. I have mains electricity! You might say. But if you are creative, here are few ideas where you want to place the gravity light at your home. Hang the gravity light in your shed, or you can use it as a porch light. You can attach a hanging basket as the weight.
