    摘要: An image projection apparatus includes an image receiver; an image processor to convert an image signal to a projection signal; a projection unit to project a projection image on a projection screen; a coordinate calculator to calculate coordinates of a point on the projection screen when the point is identified by a coordinate input device; an interactive communication unit to communicate with the coordinate input device, and an external apparatus; a user direction detector to detect a user direction where a user that performs an operation of inputting the coordinates of the point exists based on the coordinates of the point input by the coordinate input device and coordinates defining an area of the projection screen; and a screen rotation determination unit to determine whether the user is performing the inputting operation and the projection screen is to be rotated based on the detected user direction.

    摘要: A state machine gesture recognition algorithm for interpreting streams of coordinates received from a touch sensor. The gesture recognition code can be written in a high level language such as C and then compiled and embedded in a microcontroller chip, or CPU chip as desired. The gesture recognition code can be loaded into the same chip that interprets the touch signals from the touch sensor and generates the time series data, e.g. a microcontroller, or other programmable logic device such as a field programmable gate array.

    摘要: A data security system comprises a host processor, and a plurality of remote computers. Each remote computer provides biometric authentication of a user prior to responding to the user request for data access. The remote computers are handheld when in operational mode. A sensor in the handheld computer captures a biometric image while the remote computer is being used. The biometric sensor is positioned in such a way that the sensor enables the capture of the biometric image continually during computer usage with each request for access to secure data. The biometric authentication occurs in a seamless manner and is incidental to the data request enabling user identity authentication with each request to access secure data.
