I recently saw how it worked closely Touché, the system was developed for Disney Research highlight a new generation of tactile surfaces and detection based on capacitive sensors. In a new development project, Disney showed Capacitive Fingerprints, a technology that uses electricity to create ydetectar multiple users to each have a particular detection when using a multi-touch screen and interactive activities for different altogether.


Founded on the idea of ​​sharing technological devices with which we have around, the new tablets are betting on a system that is multi-touch. Least embarrassing clearer wording and concept, the multitouch is the format that is thought and developed to be standard in the coming years. Of course this is as much, but the idea of ​​multi touch is designed not for the fingers of one person, but to tell who is doing a touch on the screen and who is performing another. Multiplayer games, artistic collaboration and other uses overlook with a tablet that, by reading fingerprints instantly difference could two or more users playing surface. Disney Research has hands on the project and showed us anything in this video.

Capacitive Fingerprint is the name given to the project that tries fairy remodel the capacitive system changing physical detection by AC frequency to account for the exact electrical impedance of the fingertips in contact with the screen. As seen in the video, when a user touches the display surface, an electric capacitive sensor crosses the body thereof to the floor to measure the impedance is. What makes testing different frequencies within milliseconds, and the data provided will be used as the user profile in question. As all have a different impedance (small groups), our data will be associated with, for example, given a stroke color.



Capacitive Fingerprinting system created by Disney Research Pittsburgh has many implications for interactive design, including personalization and collaborative interaction in the contact surfaces, security and others. While still, and it shows that the delay between action and reaction is quite annoying and almost useless for fast games and activities, the evaluation of this new approach to detection shows that the technique has considerable potential and further research is needed to resolve small obstacles that are generated on the way to a final product.
