    摘要： An apparatus for a virtual input device for a mobile computing device is disclosed. In order to achieve higher throughput and accuracy of a virtual input system, the present invention is primarily characterized in that a system detects movement of a user's fingers on a work surface through at least one wearable sensor which wirelessly transmits the optical signal from the coupled transmitter to the optical receiver for processing and determining the corresponding user's input based on the predefined algorithm or pattern.

    摘要： There is a described a user interface device having first and second imaging means for forming first and second images of a three-dimensional zone from two different viewpoints, and image data generating means for generating image data corresponding to the first and second images. A processor determines the position of an object within the three-dimensional zone from the image data for the first and second images, associates the determined position with corresponding information and generates a data signal in accordance with the information corresponding to the determined position. In an embodiment, the user interface device is in the form of a virtual keyboard. In another embodiment, the user interface device is in the form of a tablet for handwriting recognition.

    摘要： A system (10) used with a virtual device (50) or transfers information to a companion device (80), and includes two optical systems OS1 (20), OS2 (60). In a structured-light embodiment, OS1 (20) emits a fan beam plane (30) of optical energy parallel to and above the virtual device (50). When a user object (110) penetrates the beam plane of interest, OS2 (60) registers the event. Triangulation methods can locate the virtual contact, and transfer user-intended information to the companion system (80, 90). In a non-structured light embodiment, OS1 (20) is preferably a digital camera whose filed of view defines the plane of interest, which is illuminated by an active source of optical energy. Preferably the active source, OS1 (20), and OS2 (60) operate synchronously to reduce effects of ambient light. A non-structured passive light embodiment is smaller except the source of optical energy is ambient light. A substraction technique preferably enhances the signal/noise ratio. The companion device (80) may in fact house the present invention.
