Abstract: A raster-type personal display is provided by vibrating an array of fiber optic filaments (32) between display limit (52, 54) by means of an electromechanical exciter (36). One end of the fiber optic filaments (32) is cantilever mounted to an array of light emitting diodes (34), with the second end of the filaments free to be vibrated by the exciter (36). Drive signals for energizing the light emitting diodes (34) are generated by a symbol generator (38) that receives synchronization pulses from a position detector consisting of a light source (58), a shutter (56) and a light responsive pickup (60).

Abstract: A personal information system wherein an illuminated information source is viewed in a mirror located closer to the eye than the shortest focal length to present in focus a visual image to the eye so that it can be viewed unobtrusively superimposed over the existing visual scene during normal activities. In a further aspect, the invention provides reflected illuminated symbolic presentation for speech interpretation assistance.
