1. An information handling system comprising:
- a processor operable to execute instructions to process information;
a memory interfaced with the processor, the memory operable to store the information;
a display interfaced with the processor and memory, the display operable to present the information as visual images, the display having touchscreen operable to detect touch inputs made at the display;
a touch controller interfaced with the touchscreen and the processor, the touch controller operable to analyze touches detected at the touchscreen and to provide inputs determined from the analyzing to the processor;
a totem resting on the touchscreen, the totem having plural contact regions at a bottom surface, the touch controller differentiating the totem from other touches based upon the spatial relationship of the plural contact regions with each other; and
a totem analyzer associated with the touch controller, the totem analyzer communicating totem position to a processor as length, width and rotation values, the totem analyzer enforcing a predetermined hysteresis for touches at the touchscreen proximate the totem.

Abstract
An information handling system touchscreen display interacts with totem devices by recognizing and tracking spectral signatures of the totem devices so that totem positions are reported as a single length, width and rotational orientation message to a host operating system. Ignore zones and hysteresis time periods are defined from the position message based upon totem context so that the host operating system processes touchscreen inputs with minimal latency and improved accuracy. Communication and battery charging are provided to the totem by the touchscreen display will illumination directed to the totem position.

9. A method for interfacing an information handling system with a totem device, the method comprising:
-
detecting plural contact regions of the totem on a touchscreen display surface; identifying the totem from a geometric pattern defined by the plural contact regions; detecting motion associated with one or more of the plural contact regions; and in response to the detecting motion, applying a predetermined hysteresis to detected touch inputs, the hysteresis delaying communication of touches proximate a totem position to a processor of the information handling system if less than all of the totem plural contact regions are detected on the touchscreen display surface. - View Dependent Claims (10, 11, 12, 13, 14)

15. An information handling system input device comprising:
-
a touchscreen display having a touch controller that detects touch positions at the touchscreen display; a totem having plural contact regions resting on the touchscreen display, the touch controller detecting the plural contact regions; a totem analyzer associated with the touch controller, the totem analyzer communicating totem position to a processor as length, width and rotation values based upon a spectral signature of the plural contact regions, the totem analyzer enforcing a predetermined hysteresis for touches at the touchscreen proximate the totem. - View Dependent Claims (16, 17, 18, 19, 20)
