Assignee:

Microsoft Corporation - Redmond WA

International Classification:

G06F 21/00

US Classification:

713189

Abstract:

A computing environment in which devices interoperate with a plurality of hardware components. Inconsistencies in user experience when operating devices that may use different components are avoided by generating a signature for the components. The signature may be computed as a function of a first key and one or more parameter values obtainable from the component. The signature and parameter values may be stored in the component's memory, and may be obtainable while the component is in operation as part of the computing device. The device may validate the component by performing at least one function based on the signature, the one or more parameter values obtainable from the component, and a second key, which may or may not be identical to the first key. The device may change its interaction with the component, depending on whether the component was successfully validated.

Abstract:

The techniques described herein are directed to a computing device that receives data from an indirect input device. The data received may indicate or signal that one or more objects are on or within a detection area of the indirect input device. For example, the data may indicate that one or more objects are in contact with a surface of an indirect touch device. The techniques include determining parameters for the one or more objects and analyzing the parameters to determine whether the data is directed to a touch operation or to a mouse operation. To perform the touch operation or the mouse operation, the techniques further describe converting the data received from a first coordinate space of the indirect input device to a second coordinate space of a display screen.
