a reference data generating unit configured to generate, when the user performs a reference data setting operation using a finger or the input instructing tool at one or more predetermined positions on the visual confirmation screen, data concerning the visual confirmation screen using the positional data of the finger or of the input instructing tool generated by the positional data generating unit based on the image data for which the operation determining unit has determined that the operation at each of the predetermined positions is a prescribed operation, and to store the generated data as reference data in a storage unit; and
an input control unit configured to determine, when the user performs the operation using the finger or the input instructing tool on the visual confirmation screen, contents of an inputted instruction, which corresponds to the operation performed by the finger or the input instructing tool, based on;
(i) data concerning the contents of the operation performed by the finger or the input instructing tool determined by the operation determining unit, (ii) the positional data of the finger or of the input instructing tool generated by the positional data generating unit, and (iii) the reference data concerning the visual confirmation screen that is stored in the storage unit, and to control the original screen to be displayed on the display apparatus in accordance with the determined contents of the inputted instruction.

Abstract
When an imaging apparatus (30) captures an image of a finger performing an operation on a visual confirmation screen (S2), an operation determining unit (73) of a computer display device (1) mounted on eyeglasses (10) determines the contents of the operation performed by the finger based on image data obtained by the imaging apparatus (30). A positional data generating unit (74) generates positional data of the finger based on the image data. Based on data concerning the determined contents of the operation performed by the finger, the generated positional data of the finger, and reference data concerning the visual confirmation screen stored in a storage unit (90), an input control unit (76) determines the contents of an inputted instruction corresponding to the operation performed by the finger, and controls an original screen to be displayed on an display apparatus (20) in accordance with the determined contents of the inputted instruction.
