Abstract
A movement-based data input device is configured to receive at least one reflected signal generated upon reflection of at least one optical signal by blood vessels of an object. The data input device may generate pattern information regarding the blood vessels of the object based on the received reflected optical signal. The data input device may determine a user input motion based on the pattern information.
Claims18
A device comprising:
- an optical signal transmitter configured to transmit at least one optical signal;
- an optical signal sensor configured to receive at least one reflected optical signal generated upon reflection of the at least one optical signal by blood vessels of a hand;
- and
- one or more processors configured to:
- generate pattern information regarding the blood vessels of the hand based on the at least one reflected optical signal;
- determine a user input motion based on the pattern information,
- wherein determining the user input motion includes determining the 3D positions of (1) a first joint connecting a palm of the user's hand and a first phalange of a finger and (2) a second joint connecting the first phalange and a second phalange of the finger based on the pattern information and/or 3D scan information resulting from 3-dimensionally sensing the hand, and
- generate an input value based on the 3D positions of the first joint and the second joint, the input value matching the user input motion.

A device comprising:
- at least one processor;
- and
- at least one computer-based memory operably coupled to the processor and having stored thereon instructions executable by the at least one processor to cause the processor to
- process at least one reflected optical signal generated upon reflection of at least one transmitted signal by blood vessels of a hand,
- generate pattern information regarding the blood vessels of the object hand based on the at least one reflected optical signal,
- generate a 3D model of the hand based on combining the pattern information and 3D scan information resulting from 3-dimensionally sensing the hand, and
- determine 3D positions of (1) a first joint connecting a palm of the hand and a first phalange of a finger and (2) a second joint connecting the first phalange and a second phalange of the finger based on the pattern information and/or the 3D scan information resulting from 3-dimensionally sensing the hand, and determine bending angles of the first joint and the second joint.
