Electronic device and a method for controlling the functions of the electronic device as well as program product for implementing the method

A device comprising:

• a display;
• a camera unit;
• a memory including program code;
• a processor;
• and
• the memory and the program code being configured with the processor to cause the device to:
• capture, via the camera unit of a device, at least two images;
• divide a first image of the at least two images into a first plurality of segments, each of the first plurality of segments having a set shape and size;
• select a fixed point from at least one segment of the first plurality of segments of the first image;
• determine a first location coordinate of the selected fixed point from the at least one segment of the first plurality of segments of the first image;
• divide a second image of the at least two images into a second plurality of segments, each of the second plurality of segments having the set shape and size, the second image being the next image following the first image of the at least two images;
• determine a second location coordinate of the selected fixed point from at least one segment of the second plurality of segments of the second image;
• calculate a movement vector of the selected fixed point between the first determined location coordinate and the second determined location coordinate;
• determine at least one of an attitude change and a position change relative to at least the movement vector;
• and
• control a visual controllable element on the display based on at least one of the attitude change and the position change.

A computer-program product comprising a non-transitory computer-usable medium having computer-readable program code embodied therein, the computer-readable program code adapted to be executed to:

• capture, via a camera unit of a device, at least two images;
• divide a first image of the at least two images into a first plurality of segments, each of the first plurality of segments having a set shape and size;
• select a fixed point at least one segment of the first plurality of segments of from the first image;
• determine a first location coordinate of the selected fixed point from the at least one segment of the first plurality of segments of the first image;
• divide a second image of the at least two images into a second plurality of segments, each of the second plurality of segments having the set shape and size, the second image being the next image following the first image of the at least two images;
• determine a second location coordinate of the selected fixed point from at least one segment of the second plurality of segments of the second image;
• calculate a movement vector of the selected fixed point between the first determined location coordinate and the determined location coordinate;
• determine at least one of an attitude change and a position change relative to at least the movement vector;
• and
• control a visual controllable element on a display of the device based on the at least one of the attitude change and the position change.
