An apparatus including a light conversion element including an input interface for receiving input light; an output interface for providing output light having at least one different, lower frequency than the input light; and a plurality of light guides extending between the input interface and the output interface that suspend down-conversion material at remote locations from the input interface, wherein the down-conversion material is configured to down-convert the received input light to produce the provided output light of lower frequency or frequencies.

A visual task or status indicator comprises a tube having a riser region extending away from a base and an illumination output region distal to the riser region. The tube has the tube wall comprising an optical diffuser material. A waveguide, such as a polycarbonate strand or other optical fiber or a bundle of optical fibers, is enclosed within and extends through the riser region into the illumination output region of the tube. The waveguide is configured to emit light laterally in the illumination output region. A light source is coupled to the waveguide. The light source can have a plurality of output light modes, including various colors or intensities or patterns of colors and intensities. Control circuitry is connected to the light source to select the output light modes in response to a control signal. A plurality of indicators can be controlled from a central control hub.

An active, specialized stylus and sharp color graphics may be combined with a tactile display in order to increase accessibility to the blind and visually impaired. A tactile display may consist of an array of pins that may be raised to varying heights to represent contours and outlines of images that are recognizable when touched. A specialized stylus may allow the user to instantly create, touch and save tactile drawings or alter with multi-sensory feedback. A tactile and visual display may consist of an array of pins, with circular or squared-off tops. Physical attributes may be given to individual pins, the screen itself (LED), or a LCD WXGA or other type of projector may be incorporated so that enhanced visual imaging is combined with tactile graphics to give those with different levels of visual impairment a multisensory feedback when experiencing images or drawings. Also this technology may be used with autistic students and those with learning disabilities, as well as serve as a means of entertainment.
