Input tools having vibro-acoustically distinct regions and computing device for use with the same

摘要

An input tool includes a body in the form of a stylus with plurality of vibro-acoustically distinct regions. The vibro-acoustically distinct regions produce vibro-acoustic responses when the regions touch the surface of the touch screen. The vibro-acoustic responses are used in a computing device to detect what region of the input tool was used.

主权项

1. A passive input tool for interacting with a touch screen, the passive input tool comprising:
a body in the form of a stylus, the body having different materials adjacent to one another, each of the different materials having a different material property and forming a vibro-acoustically distinct region, wherein each vibro-acoustically distinct region produces a discrete vibro-acoustic signal when the passive input tool touches a surface of the touch screen, and wherein the vibro-acoustic signal is used to detect what region of the passive input tool was used.
