At a small conference in San Jose, Calif., participants talked about the future of interactive displays--and where the money is.
SAN JOSE, Calif.--At the Interactive Displays 2009 conference here Wednesday, a small group of participants aimed to figure out not just where the science of touch and gesture is headed, but also where the dollars are.
Artificial Muscle has been working on improving haptic feedback for gadgets for the last six months. Here, a Lenovo IdeaPad has been outfitted with Artificial Muscle's proprietary actuators underneath the touch pad (shown sitting on top).
When mousing over different areas of a screen, haptic feedback, which feels like a buzz or small vibration, will be felt in the touch pad of the computer. The actuators respond to audio signals in the computer and cause the haptic feedback.
Joey Yu Zhao, CEO of San Jose-based 22miles, demonstrates the use of multitouch technology for manipulating video. In this case, Zhao used his finger to overlay a drawing and then used a larger object, his cell phone, as an eraser.
JDSU makes a coating for LCD screens that prevents heat damage to devices used in direct sunlight or heat. Here the company demonstrates the product, called IR Blocker 70.
The heat lamp is set up very close to a laptop whose screen is half covered in the protective layer, with the other half left unprotected. The black mark on the right side is the effect of the lamp burning the LCD screen. It can be used in outdoor displays, GPS systems, ruggedized PCs, and commercial kiosks.
Here, Artificial Muscle's Smart Move haptic technology is shown in a touch-screen application, such as what could be used in a kiosk at a supermarket or airport. The volume dial causes a buzzing sensation to be felt as each click of the dial is passed over with a finger.
In discussing his inspiration for his work in multitouch, Jeff Han of Perceptive Pixel pointed to a mid-1980s PBS video he saw of Bill Buxton (shown here) discussing one of the earliest implementations of multitouch.
Synaptics provides the touch-screen technology inside devices like the T-Mobile G1 phone and HP's Voodoo Envy laptop. Here, the G1 is pictured on the left. In the middle is the Synaptics sensor used inside the touch screen. On the far right is the sensor used in the Envy.
