Science of the Senses – Touch

This Youtube video is about science of touch. The summary:

“Touch, expressive and intuitive. Complex in design and function. Essential to our very development. No other sense does more to define us than the sense of touch. And yet most of us move through life, completely unaware of the myriad ways we use it, not only to feel the world, but to move within. In The Science of the Senses: Touch we will take a journey through the skin, into the subcutaneous world of our sensory receptors and up into the brain as we explore the hidden language of our most essential sense. Along the way we will meet Ian Waterman, a man who has lost his sense of touch and developed some amazing strategies to compensate for his loss. We'll visit a blind artist whose astonishing drawings demonstrate the power we may all possess to visualise the world by feeling it. And we'll discover what a race car driver and a surgeon have in common when it comes to utilizing this extraordinary sense and why a revolutionary new prosthetic, one which taps into the amazing power of the human brain, may one day restore the sense of touch to amputees.”

“The objective of this work is the construction of an active artificial whisker system which closely corresponds to the external parts of the whisker system in rodents. The development of the artificial whiskers will be the basis for subsequent robot experiments. We were developing a tactile sensor which is responsive to whisker deflection and vibration. The tactile sensor system can measure angular direction, frequency, and deflection amplitude of the artificial whisker, which corresponds to the capabilities of the mechano-receptive sensory systems in rodents.”

Mgestyk’s Free-Hand 3D Gestural User Interface

Mgestyk is a technology company that provides a free-hand 3D gestural user interface like Oblong industries. Below is the description of their technology:

“Mgestyk combines powerful software for hand-gesture language processing with an affordable 3D camera. Our patent-pending technology makes it possible to capture small hand movements and translate them into useful commands for controlling practically any Windows application.

Whether it's a simple cursor for browsing the web or a complex set of two-handed gestures for Flight Simulator, our desktop software makes it easy to map gestures to custom actions.

Since gesture processing is done directly on 3D data, any data beyond a certain depth (such as background color or people walking behind you) can be ignored and will not affect accuracy. Processing is also not affected by the lighting in the room.

Best of all, there are no special gloves to wear or brightly-colored objects to hold.”

Keyboard Goes Multi Touch

Microsoft SideWinder X4 Multitouch Keyboard

Microsoft unveiled Microsoft SideWinder X4 Keyboard with many new features. The most impressive enhancement is anti-ghosting that may be regarded as a keyboard edition of multi touch technology.

“The advanced technology takes anti-ghosting to the next level by allowing gamers to press up to 26 keys at once. Because each key is scanned independently by the keyboard hardware, each key press is correctly detected regardless of how many other keys are being pressed at the same time.”

What is more interesting with SideWinder X4 is that Paul Dietz has contributed to developing it. He developed DiamondTouch that is one of the first capacitive multi touch systems and is available through Circle Twelve.

Issues and Techniques in Touch-Sensitive Tablet Input (Video)

Bill Buxton has uploaded an accompanying video clip of his famous touch UI paper entitled “Issues and Techniques in Touch-Sensitive Tablet Input”.


LCD Multi Touch Using Inverted FTIR Technology

Researchers at TUM have developed an LCD multitouch setup using an overhead camera and FTIR technology. The authors call the combination Inverted FTIR.


Inverted FTIR: Easy Multitouch Sensing for Flatscreens


The main difference of Inverted FTIR compared with FTIR multi touch comes from the fact that camera is placed over the screen. So, an LCD display is easily integrated into the FTIR multi touch system.

Gesture Cube – The First Commercial 3D Capacitive Touch Interface?


Recently, I’m continuously surprised by many companies and people who bring out cool technologies sleeping in the piles of research papers. Today’s surprise is Gesture Cube, which is the result from the joint work of three companies  - IDENT Technology AG, ZINOSIGN®, LUNAR Europe

“Gesture Cube uses 3D spatial movement tracking to help transform navigating a device into a magical intuitive experience. The underlying GestIC® technology detects your hand´s approach and movements - your favorite apps and media all at a wave of your hand.”

At this time, the web site contains the video of concept scenarios only, not a real working system.



However, IDENT Technology AG provides the working example of GestIC® that is used in Gesture Cube.



Simply speaking, Gesture Cube is a portable information/entertainment device that you can control with direct and proximal touch gestures. Each surface of Gesture Cube has its own touch sensitive display that can detect both of touch and proximity.


Overall, it shows us an awesome implementation of two interesting research topics in the field of touch user interface.


All-Surface Interaction

Unlike traditional touch interfaces, the interaction of Gesture Cube is performed across two or more surfaces of the device. Many researchers have proposed similar works - hand grip recognition, back-of-side interaction, and Cubtile. There are also prototypes that have touch sensors and LED arrays covering the whole surfaces of devices (gCubik, FentixCube, and Z-agon). But the advancement of Gesture Cube comes from the fact that all of its surfaces are covered with advanced touch screens.

Advanced 3D capacitive touch technology

It adopts electric field sensing (or electric field imaging) technology that was fully investigated by Joshua Smith, who was an MIT student and now is working with Intel Research. Electric field sensing is a variant of traditional capacitive sensing that is specialized for detecting 3D movement of a remote conductive object. Besides electric field sensing, there are other works implementing 3D capacitive sensing (Thracker, EtherTouch, and so forth). From the concept video, it seems that the 3D sensing and conventional touch screen technologies are well merged with each other.

A few days ago, I tweeted Touchco stopped doing business. At that time, I roughly guessed that it was acquired by a touch screen company, but never imagined that it is Amazon.
From the technical point of view, however, Touchco is a good choice for Amazon.
You know that Amazon’s Kindle uses E-ink display. And Touchco showed off two interesting demos showing the possibility of applying its IFSR technology to flexible E-ink display (Unfortunately, Youtube demo clips are not public now).
