Abstract

The present application relates to adapting a user interface based on context information. In the method, apparatus and system according to the present application, a context vector (920) is used to select a plurality of resource availability vectors (930, 940, 950). The plurality of resource availability vectors are indicative of availability of user resources in the corresponding context. The selected resource availability vectors are then used together in adapting a user interface (960, 970, 980) according to the availability of the user resources. There is also a method and devices for forming a data structure that can be used in the selection of the resource availability vectors. The method may select from different user interface modalities (960, 970, 980) by processing sensor input data with an associative memory, such as a sparse distributed memory.

modifying the selected resource availability vectors using a teaching resource availability vector associated with said context vector.

50. A method according to claim 49, comprising

modifying said selected resource availability vectors by increasing the value of the elements corresponding to an available resource in said teaching resource availability vector.

51. A method according to claim 49, comprising

modifying said selected resource availability vectors by decreasing the value of the elements corresponding to an unavailable resource in said teaching resource availability vector.

52. A method according to claim 49, comprising

using a distance measure in said selecting, and

modifying said selected resource availability vectors according to said distance measure.

53. A method according to claim 49, comprising

thresholding said teaching resource availability vector, and

modifying said selected resource availability vectors using said thresholded teaching resource availability vector.
