Abstract: According to an example aspect of the present invention, there is provided an input device and corresponding method which digitizes and transforms minute hand movements and gestures into a directive ray without interfering with the normal use of one's hands. The device and method may, for example, at least participate in computing the directive ray based on received information from a plurality of sensors, where the sensors are preferably of different types.

Abstract: Devices, methods and computer programs for estimation of force applied by a finger based on wrist surface topography are disclosed. A computing unit (200A, 200B) receives, from a group of proximity sensors (300) mounted on an inner surface of a wristband (111) of a wrist apparatus (110A, 110b) communicatively connected to the computing unit (200A, 200B), a detected proximity of each proximity sensor (300) to a wrist surface of a user wearing the wristband. The computing unit (200A, 200B) measures changes in wrist surface topography based on the detected proximities, and estimates a force applied on a surface by at least one finger associated with the wrist based on the measured changes in the wrist surface topography.
