Abstract

A method for determining a viewing configuration of a rendered figure of a rehab-patient or a sports trainee, aiming to deliver a suitable view on the rendered figure, the method comprising the steps of capturing motion data in the 3D space of one or more body parts of the rehab-patientor the sports trainee and providing them to a computer; and further the step of performing on the computer measurements of deviation of the captured motion data from a reference list of motion data and/or measurements of main motion direction; and based on the results of the above measurements, determining the viewing configuration.

Claims

1. A method for determining a viewing configuration of a rendered figure of a human body, the viewing configuration comprising the rotation, tilt, zoom and other parameters of the rendered figure, for generating a suitable view on the rendered figure, the method comprising the steps of:

capturing motion data in a 3D space of one or more body parts and providing the data to a computer;

rendering a figure that mimics the movement of the human body

taking measurements of deviation of the captured motion data from a reference list of motion data and/or measurements of main motion direction; and

based on the results of the above measurements, determining the viewing configuration of the rendered figure.

2. A method according to claim 1, wherein the method is performed within time frames and wherein the determination of the viewing configuration within a certain time frame takes the said measurements during previous and further time frames into account, for the purpose of providing stable or complementary viewing configurations.

7. A method according to claim 1, wherein the measurement of the deviation of the captured motion data from a reference list of motion data, comprises the steps of providing reference values, for example by capturing the same motion data from an ideally performed exercise or by calculating a mean value of previously captured motion data;

and calculating a measurement of distance between the reference values and captured values.

9. A method according to claim 1, wherein the main motion direction is determined using the summation of velocity vectors and using the direction of the sum vector.

10. A method according to claim 1, wherein main motion direction is determined using projections of velocity vectors.

11. A method according to claim 1, wherein an area of interest is selected based on the measurements, the selected area of interest directly determining the viewing configuration on the basis of a mapping table defining a relation between any area of interest and parameters of a viewing configurations.

16. A method according to claim 1, wherein more than one viewing configuration is represented simultaneously.
