Wearable data input interface

A method of entering data into a computer device, comprising:

• providing a wearable device (10) having an extension (14, 16, 18, 20, 22), the extension (14, 16, 18, 20, 22) having a sensor (50, 52, 54, 56, 58) in operative engagement with a sensor channel (15, 17, 19, 21, 23) mounted thereon;
• placing a hand (200) on top of the device (10) so that the extension (14, 16, 18, 20, 22) is positioned immediately below a metacarpophalangeal joint (212) and a first bone segment (202) of the hand (200) and the sensor channel (15, 17, 19, 21, 23) extends under and across the joint (212) and into the extension (14, 16, 18, 20, 22);
• moving the first bone segment (202) to change a direction of the bone segment (202) relative to a second bone segment (214) of the hand (200) at the metacarpophalangeal joint (212);
• the movement of the bone segment 202 bending the sensor channel (15, 17, 19, 21, 23) that extends across the metacarpophalangeal joint (212);
• the sensor (50, 52, 54, 56, 58) sensing the bending of the sensor channel (15, 17, 19, 21, 23) due to the change of direction of the bone segment (202) at the metacarpophalangeal joint (212);
• and
• the sensor (50, 52, 54, 56, 58) sending an activation signal (57) to a computer device (11) in operative engagement with the device (10).
