User gesture recognition

摘要

An apparatus comprising: at least one processor; and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to perform: determining at least one parameter dependent upon a user gesture wherein the parameter is rotation invariant, having the same value when determined at different arbitrary orientations between the apparatus and the user gesture; and using the at least one parameter to determine an action in response to the user gesture.

1. An apparatus comprising:
at least one processor; and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to perform: in a first state, enabling use of a first set of user actuations proximal to a proximity detector as a first set of valid user actuations, wherein each of the first set of user actuations comprises user gestures that are dependent at least in part on a rotation of the apparatus; in response to detecting a first criteria, changing from the first state to a second state; and in the second state, disabling at least one of the first set of user actuations and enabling the use of a second set of user actuations proximal to the proximity detector and different to the first set of user actuations, as a second set of valid user actuations, wherein the second set of valid user actuations comprises user gestures that are invariant in effect if the apparatus is rotated relative to the user actuations.
