US 2017/0285855 A1 · METHOD AND SYSTEM HYBRID STYLUS

Abstract

Embodiments of the present invention are directed to systems for improved touch screen user-input devices that combine the benefits of active and passive touch screen implementations. According to one or more embodiments of the present invention, a system is provided that includes a user input touch device (such as a stylus) that can be equipped with one or more tips of various sizes and shapes, and a touch screen input surface that is configured to detect each of the various tips. In contrast to prevailing conventional active stylus implementations, this allows touch screen implementations to use styluses with tips that simulate real-world artistic tools that are currently not available in digital arts media. Moreover, data obtained in the input device itself is communicated to the touch screen processor/controller to supplement the input data received in the touch screen device.
