    摘要: An apparatus (1) for rotating objects (40) on screens (9) defines a hand axis (20) in response to 3D position information related to the hands (21, 22) of a user and detects a changed orientation of the hand axis (20) with respect to a 3D space and calculates a rotation for the object (40) on the screen (9) in response to said detecting. This way, to rotate the object (40) on the screen (9), an imaginary copy of the object (40) is considered to be inside an imaginary ball (41) held by the user, which imaginary ball (41) is being rotated. The changed orientation of the hand axis (20) comprises changes in angles between the hand axis (20) and the axes (31, 32, 33) of the 3D space. To improve stability in case of each one of said changes being unequal to zero, the apparatus (1) further detects the angles and compares the respective angles with respective thresholds and reduces or weights the respective changes in response to respective comparison results.
