The TABULA Project
Capacitive detection of objects on a touchscreen
Large touchscreens, on which touchable objects, or ‘tangibles’, can be placed and moved around, are especially valuable in education applications. However, it has so far not been possible to use these in conjunction with capacitive touch sensors of the sort found on modern tablets and large touch panels such as the Microsoft Surface Hub. A research project at RWTH Aachen in Germany seeks to change this state of affairs, with a bit of help from Elektor.
