1. A wearable device for determining a position of at least one finger of a hand relative to a predetermined reference point comprising:
a sensor unit configured to be arranged in the palm of the hand comprising:
at least one sensor configured to register positions of said at least one finger in relation to the wearable device; anda logic unit in operative engagement with a computer device and configured to generate a position signal based on the registered finger position, and to interpret and convert the signal to a command to be processed by the computer device; a housing at least partly enclosing the sensor unit having an opening for the at least one sensor; and an attachment member configured to attach the sensor unit to the hand, wherein the at least one sensor comprises at least one camera directed towards a respective distal end of the at least one finger and configured to determine the position of the finger in relation to the wearable device, and the sensor unit further comprises a second sensor, which is a camera and configured to, in cooperation with the first image sensor, obtain accurate 3D-measurements of the position of the at least one finger and/or to determine the position and orientation of the hand relative to the surface under the hand and/or in relation to the other hand, and/or in relation to another part of a human body, and whereby the logic unit further comprises an inertia measurement unit configured to also measure a translational and rotational movement of the hand, and sensors configured to send signals, as a result of registered positions and movements by the sensors, whereby sensors continuously send signals to respectively calculating units that enable two or more signals to be calculated in the same circuit at the same time by temporarily combining them into a single signal such that a calibration can be performed of the movements of at least one finger and/or hand by moving said finger in one or more predetermined direction and distance in relation to the reference point and in a predetermined direction at a predetermined velocity, whereby for the fingers, the reference point is the wearable device, and for the hand, the reference point is the surface under the hand. |
