Electronic device and the input and output of data

This invention describes a system where a touch screen device can identify specific physical objects placed on its surface. Each object has multiple conductive points that touch the screen, creating a unique pattern of contact points. The device recognizes the object by sensing the specific distances and arrangement of these contact points, with the primary claims focusing on objects having at least three contact members.

Why it matters: Filed before high-resolution, multi-touch screens and powerful mobile processors were standard. These advancements make precise object identification and interactive gaming applications more feasible now.
