Abstract: A multi-purpose stylus and method for communicating and interacting with a computing device both through physical contact and wirelessly. Embodiments of the stylus and method facilitate the use of the stylus as both a physical input instrument (by contacting a surface of the computing device to input data) and as a remote wireless instrument using a variety of auxiliary devices. Many types and combinations of auxiliary devices may be incorporated into embodiments of the stylus and method. These include one or more microphones and speakers, a laser pointer, a camera, a color sensor for obtaining color coordinates of an object, and an accelerometer to identify and interpret user gestures. Moreover, identification and authentication of a user may be achieved by including a fingerprint sensor and an identification device having a unique identifier. A transceiver is used to wireless communicate and control remote devices and the computing device.

Abstract: A reduced-latency ink rendering system and method that reduces latency in rendering ink on a display by bypassing at least some layers of the operating system. “Ink” is any input from a user through a touchscreen device using the user's finger or a pen. Moreover, some embodiments of the system and method avoid the operating system and each central-processing unit (CPU) on a computing device when initially rendering the ink by going directly from the digitizer to the display controller. Any correction or additional processing of the rendered ink is performed after the initial rendering of the ink. Embodiments of the system and method address ink-rendering latency in software embodiments, which include techniques to bypass the typical rendering pipeline and quickly render ink on the display, and hardware embodiments, which use hardware and techniques that locally change display pixels. These embodiments can be mixed and matched in any manner.

Abstract: An optical security device can be used to view sensitive information provided in an obscured format via a potentially untrusted and/or compromised computer. The techniques described herein enable use of untrusted computers for access to sensitive information. The optical security device employs one or more forms of visual cryptography such as spatial cryptography and/or temporal cryptography in some instances via a programmable mask and/or a programmable color filter to reveal sensitive information that is provided in an obscured form by a potentially untrusted computer.
