Abstract:
Disclosed herein is a wearable eyeglass device including: an optical communication module receiving a first optical signal and transmitting a second optical signal; a display module displaying information corresponding to at least one of the first and second optical signals; and a control module controlling the display module to display first information corresponding to the first optical signal at the time of receiving the first optical signal and controlling the optical communication module to transmit the second optical signal corresponding to second information.
Abstract:
Disclosed herein is a user interface device for a projection computer and an interface method using the user interface device, which provides interaction between a user and the projection computer that outputs results by means of a projector, by using a hand and an infrared pen on the projection computer. The user interface device for a projection computer includes a projector unit for outputting results of the projection computer. A pattern light generation unit outputs infrared pattern light to a result output area to which the results are output. A camera unit obtains an image by capturing the result output area An image processing unit recognizes at least one of a user's hand and an infrared pen based on the image obtained by the camera unit. A control unit controls the pattern light generation unit, the camera unit, and the image processing unit based on a recognition mode.
