The present invention is based on a touch based control of a user terminal. The touch based control may comprise a touch screen, a touch pad or other touch user interface enabling "multitouch", where a touch sensing surface is able to recognize presence of two or more touch points. Two detected touch points on the sensing surface define end points of a line segment. Length of the line segment is determined providing basis for a first control signal and angle of the line segment compared to a reference line is determined providing basis for a second control signal. These control signals are used to control a moving object in a virtual space. |
