Abstract
The invention relates to method and a system of interpreting angular orientation data. It is determined, whether the angular deviation of a current angular orientation (C) of a sensor device (12) from a last extreme angular orientation (L) currently decreases after having increased before up to a provisional new extreme angular orientation (P), thereby determining that the provisional new extreme angular orientation (P) is a new extreme angular orientation. Information relating to a new extreme angular orientation, such as an angular range of motion, may be output to a user.
Claims14
A method of interpreting angular orientation data, comprising the steps of:
- receiving angular orientation data from a sensor device, said angular orientation data comprising information about a current angular orientation in space of the sensor device relative to a reference orientation;
- and
- determining whether the angular deviation of the current angular orientation from a last extreme angular orientation currently decreases after having increased before up to a provisional new extreme angular orientation, thereby determining that the provisional new extreme angular orientation is a new extreme angular orientation.
A system for interpreting angular orientation data of a body part, the system comprising:
- a sensor device for being attached to the body part;
- and
- an interpreter device, the interpreter device being arranged for:
- receiving angular orientation data from the sensor device, said angular orientation data comprising information about a current angular orientation in space of the sensor device relative to a reference orientation;
- and
- determining whether the angular deviation of the current angular orientation from a last extreme angular orientation currently decreases after having increased before up to a provisional new extreme angular orientation, thereby determining that the provisional new extreme angular orientation is a new extreme angular orientation.
