Method for issuing an input to a computer from a head-mounted device
The invention relates to a method for issuing an input to a computer from a head-mounted device, the head-mounted device comprising a processing unit and a memory as well as at least one position and/or movement sensor, the head-mounted device being in communication with the computer, the method being implemented while the head-mounted device is worn on a wearer's head. The method comprises steps of: acquisition of position and/or movement data representative of the movement of the wearer's head by the position and/or movement sensor, detection of a specific movement pattern based on said position and/or movement data, the specific movement pattern being taken from a library of movement patterns, determination of a specific input associated with the specific movement pattern in the library, and issuance of the specific input to the computer.
1 . A method for issuing an input to a computer from a head-mounted device, the head-mounted device comprising a processing unit and a memory as well as at least one position and/or movement sensor, the head-mounted device being in communication with the computer, the method being implemented while the head-mounted device is worn on a wearer's head, the method comprising steps of:
acquisition of position and/or movement data representative of the movement of the wearer's head by the position and/or movement sensor,
detection of a specific movement pattern based on said position and/or movement data, the specific movement pattern being taken from a library of movement patterns,
determination of a specific input associated with the specific movement pattern in the library, and
issuance of the specific input to the computer,
wherein the specific input acts as a predetermined combination of multiple keyboard key presses without the wearer actually performing the key presses on the keyboard,
wherein the specific movement pattern comprises at least one head rotation movement along a yaw, pitch and/or roll axis, with a predetermined angular amplitude threshold,
wherein the predetermined angular amplitude threshold is compounded with a minimum duration of crossing said threshold for detecting the specific movement pattern, and
wherein the specific movement pattern comprises at least one finger tap on a frame of the head-mounted device.
2 . The method according to claim 1 , wherein the head-mounted device is in communication with the computer through a wireless communication protocol.
3 . The method according to claim 1 , wherein the library is stored in the memory of the head-mounted device, the steps of detection, determination and issuance being implemented on the head-mounted device, by the processing unit.
4 . The method according to claim 1 , wherein the at least one position and/or movement sensor is an inertial motion unit comprising at least one accelerometer, at least one gyroscope and/or at least one magnetometer.
5 . The method according to claim 1 , wherein the head-mounted device is registered on the computer as a keyboard and/or mouse.
6 . The method according to claim 1 , wherein the library of movement patterns further comprises at least one head translation movement along a frontal, lateral or vertical axis, with a predetermined length, speed, or acceleration threshold.
7 . The method according to claim 1 , wherein the library of movement patterns further comprises a modification of a resting position of a frame of the head-mounted device on the face of the wearer.
8 . The method according to claim 1 , wherein the computer is running a game program, the input being issued to the computer corresponding to an in-game action related to the specific movement pattern associated with the input in the library.
9 . A non-transitory computer-readable storage medium comprising a computer program which, when executed by a processing unit of a head mounted device comprising at least one position and/or movement sensor and in communication with a computer, enables the implementation of the method according to claim 1 .
10 . The method according to claim 1 , wherein the specific input acts as a predetermined combination of at least one mouse movement and/or at least one mouse key press without the wearer actually operating the mouse.
