Abstract:
A stylus can include a housing and a tip. A force-sensing system can detect movement of the tip relative to the housing when a force is applied to the tip. A haptic feedback system can move the tip relative to the housing, for example by inducing a magnetic field in magnetic elements connected to the tip and the housing. The haptic feedback can be used to render texture sensations to simulate drawing on a textured surface with the stylus. As such, the same tip that is used to provide inputs can receive haptic feedback during use. The user can continue to use the tip for input even as haptic feedback is also being applied to the tip.
