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 a touchscreen operable to detect touch inputs made at the display;
a scaler integrated in the display and interfaced with the host, the scalar operable to adapt visual information communicated from the host to a display format for presentation as visual images; and
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, the touch controller interfaced with the processor and the scalar;
wherein the scalar receives touch inputs and selectively applies the touch inputs directly from the touch controller to adjust display settings.

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 and display, the method comprising:
-
interfacing a touch controller of the display with a processor of the information handling system, the touch controller detecting touches at the display and communicating the touches as inputs to the processor; interfacing the touch controller of the display to a scalar of the display, the scalar accepting graphical information from the information handling system and adapting the graphical information for presentation as visual images at the display; tracking a context of inputs made at the display and detected by the touch controller; and directing the inputs from the touch controller to one of the processor or the scalar based upon the context. - View Dependent Claims (10, 11, 12, 13, 14)

15. An information handling system input device comprising:
-
a touchscreen panel operable to present visual information as images and accept touches as inputs; a scalar interfaced with the touchscreen panel and operable to adjust graphical information provided from host for presentation as visual images at the touchscreen panel; a touch controller interfaced with the touchscreen panel and operable to convert touches to input signals; and a context engine associated with the touch controller, the context engine defining first and second context touch areas, the touch controller communicating inputs detected in the first context touch area to the scalar and communicating inputs detected in the second context touch area to a host information handling system. - View Dependent Claims (16, 17, 18, 19, 20)
