![]() You know something (or somebody) is good when people start making fan sites for ’em. Total internal reflection is an optical phenomenon, which occurs when a ray of light strikes a boundary between two medium with an angle larger than the critical angle respect to the other medium. military, too, but also can’t wait to start on another earth-shattering endeavor. In this paper, we present a new approach to FTIR sensing by 'inverting' the setup and placing the camera in front of the screen. FTIR is a touch system which uses total internal reflection to separate touch object from background. He is in talks with certain branches of the U.S. Han has also launched a startup, Perceptive Pixel, that markets the technology as the most advanced of its kind. The FTIR approach is based on optical total internal reflection within an interactive surface. ![]() The last one is an added treat to the article featuring the screen in Fast Company’s February 2007 issue and is spreading oh-so-virally like its siblings (it’s how I bumped into the whole thing). Inverted FTIR: easy multitouch sensing for flatscreens. Han’s work in 2005, which utilized the principle of FTIR in multi-touch interaction, can be seen as the turning point in both the interest and development of such optical systems. While the previous demonstrations already showed 3D, I was particularly intrigued by the few seconds they showed a 3D rendering of a face with its mesh being manipulated, affecting its shape.

Zoom into your photos, twirl 3D maps around, and more. FTIR Frustrated Total Internal Reflection (a phenomenon) This is currently the most popular method, possibly due to the wide internet distribution of Jeff Han’s videos. Shown here is a 2D game where you shoot the enemy “UFOs” with a slingshot-like weapon, requiring two hands and multiple fingers! TEDTalks DemonstrationĪ lava lamp program that lets you add heat and mold them to your liking. (paper at ACM UIST 2005: Low-Cost Multi-Touch Sensing through Frustrated Total Internal Reflection) The main idea behind the technology: the prototype is able to handle multiple touch inputs at the same time, even varying degrees of pressure, based on the FTIR concept used in fingerprint scanners. Multitouch materials and references Looks like well be making a touch screen using the FTIR (Frustrated Total Internal Reflection) technique. Jefferson Han‘s multi-touch screen system requires not too many words to describe it, only a few videos (represented here in thumbnails, though): Multi-Touch Sensing through FTIR The 65TR3BF-B 65 IR Touch Screen Display supports pen and multi-touch function and features Air Class and web browser support to create an interactive.
