Title:
NON-CONTACT INPUT DEVICE, NON-CONTACT INPUT METHOD, AND NON-CONTACT INPUT PROGRAM
Document Type and Number:
Japanese Patent JP2023132547
Kind Code:
A
Abstract:
To provide a non-contact input device, a non-contact input method, and a non-contact input program that accurately determine an indicated point intended by a user.SOLUTION: A non-contact input device 100 comprises a display unit 10, a first sensor 20, a second sensor 30, and an indicated coordinate calculation unit 40. The first sensor 20 detects a position of a pointer in a planar first detection area placed in front of the display unit 10, and the second sensor 30 detects a position of a pointer in a planar second detection area placed in front of the first detection area. The indicated coordinate calculation unit 40 calculates indicated coordinates above the display unit pointed by the pointers based on a distance D that is a distance between the display unit and the first detection area, a distance d that is a distance between the first detection area and the second detection area, first coordinates that are positional coordinates of the pointer in the first detection area, and second coordinates that are positional coordinates of the pointer in the second detection area.SELECTED DRAWING: Figure 1
