摘要
A tactile imaging interface to the human body is disclosed for operation in combination with an input transducer (typically a solid-state image sensor), and suitable conversion electronics. A fluid jet, preferably discharging water, is deflected by electro-mechanical motors (typically a galvanometer) such as is used to drive pen motors and modulated in discharge pressure to impinge its resultant discharge jet on a thin flexible membrane in contact with a mechanically sensitive skin area. The conversion electronics drive the galvanometer motor controls for deflection and modulate the jet discharge in response to the input transducer which is typically an image sensor receiving an image. By the expedient of providing the transducer (or image sensor) and jet with either a conventional raster scan or a preferred cursive scan, or cursively tracing a stored, raster scanned image (by a cursive tracing algorithm in an analog or digital computer), or slowly tracing fast oscilloscope wave forms onto the skin by the use of a conventional sampling amplifier, transduced information supplementing or replacing a sensory modality (typically lost vision) is transmitted to the human tactile nervous system through the membrane.
