Abstract
The invention relates to a method of locating a first device for wirelessly communicating with a second device relative to each other. The invention further relates to a system comprising a first device and a second device adapted for wirelessly communicating with each other. The object of the present invention is notify a user of an appropriate position of a first device relative to a second device with a view to ensuring proper wireless communication between them. The problem is solved in that one or more light sources are used to notify the user of appropriate locations of the two devices relative to each other according to a predefined correspondence scheme between appropriate beam patterns and distances between the devices The invention has the advantage of assisting a user in attaining a correct or appropriate distance between a first device (e.g. a programming device) and a second device (e.g. a device to be programmed). The invention may e.g. be used for programming or uploading data from a programming or server device to a portable audio device (e.g. a hearing aid) or to an entertainment device (e.g. a music player or a head set).
