Patent number: 8519950Abstract: An input device for a user interface comprises means to monitor movement of a user by mapping and recording deformations of their skin. The input device comprises conformable/reversibly stretchable material for placement onto the skin of a user. A plurality of sensors are mounted on, or embedded in, the stretchable material and arranged to undergo, and track in-plane and out-of-plane deformations corresponding to stretching and flexure of the underlying skin. A signal for controlling another device is then generated, based on the detected movement, gesture or positioning of the user based on the detected deformations. In wearable electronics applications, the other device may be mounted on the same stretchable material. The sensors may be arranged to provide active feedback, by selectively applying vibrations or pressure to the user's skin.Type: GrantFiled: November 19, 2007Date of Patent: August 27, 2013Assignee: Nokia CorporationInventors: Zoran Radivojevic, Jarkko Tapio Saunamaki, Teuvo Tapani Ryhanen, Stephanie P.

Publication number: 20130106774Abstract: An apparatus including a processor and a memory including computer program code. The memory and the computer program code are configured to cause the apparatus to, for an array of capacitive touch sensors with a proximally positioned electrotactile layer, compare the capacitance associated with a capacitive touch sensor of the array against a respective detection threshold to determine whether or not a touch input has occurred at the capacitive touch sensor by a stylus in capacitive coupling proximity to the capacitive touch sensor. The detection threshold of one or more capacitive touch sensors of the array is set to be sufficient to inhibit the erroneous generation of a touch input signal at the one or more respective capacitive touch sensors caused by capacitive cross-coupling, via the electrotactile layer, to the capacitive touch sensor which is in capacitive coupling proximity to the stylus.Type: ApplicationFiled: August 16, 2012Publication date: May 2, 2013Inventors: Zoran RADIVOJEVIC, Paul BEECHER, Chris BOWER, Piers ANDREW, Darryl COTTON, Samiul HAQUE
