Kobo touch technology

Hi all

Can someone enlighten (or post some links) on what kind of technology is used for the touchscreen in the Kobo reader (I want to shine near my girlfriend )?

thx!

The Kobo Touch operates on an Infra Red detection system

A series of vertical and horizontal lines are beamed across the face of the screen, like graph paper

When a finger or stylus breaks the lines, it stops the transmitted infrared beam being picked up by the receiver on the opposite side which activates the firmware to complete the function such as page turn etc

When it is described like that, I wonder if a shiny finger can reflect the beam back to a different receptor resulting in confusion for the device and as a result cause various effects that we label bugs.

It does! The most reflective part of a finger is usually the fingernail. So you have often trouble to trigger a desired action by tapping near the top edge.

I first saw IR touch screen in 1981 same time frame of Osborn luggable computer.

Neonode used to make touchscreen phones using the same technology
