Abstract
According to one embodiment, a method, computer system, and computer program product for dynamic braille actuation is provided. The embodiment may include receiving a plurality of media. The embodiment may also include translating one or more visual elements of the received plurality of media to braille. The embodiment may further include generating a plurality of protrusions corresponding to the one or more translated visual elements on a surface of a stretchable display screen using microfluidic actuation.
Claims20
A processor-implemented method, the method comprising:
- receiving a plurality of media;
- translating one or more visual elements of the received plurality of media to braille;
- and
- generating a plurality of protrusions, each raised to a preconfigured height on a surface of a stretchable display screen by a plurality of embedded actuation electrodes, corresponding to the one or more translated visual elements using microfluidic actuation, wherein the plurality of protrusions are generated by a plurality of microfluidic droplets and color LED pixels raised by the plurality of embedded actuation electrodes, and wherein a subset of three or more actuation electrodes within the plurality of embedded actuation electrodes are aligned vertically, and wherein a single actuation electrode within the subset is closed while all other electrodes in the subset are open, and wherein each microfluidic droplet is set beneath a color LED pixel.
A computer system, the computer system comprising:
- one or more processors, one or more computer-readable memories, one or more computer-readable tangible storage medium, and program instructions stored on at least one of the one or more tangible storage medium for execution by at least one of the one or more processors via at least one of the one or more memories, wherein the computer system is capable of performing a method comprising:
- receiving a plurality of media;
- translating one or more visual elements of the received plurality of media to braille;
- and
- generating a plurality of protrusions, each raised to a preconfigured height on a surface of a stretchable display screen by a plurality of embedded actuation electrodes, corresponding to the one or more translated visual elements using microfluidic actuation, wherein the plurality of protrusions are generated by a plurality of microfluidic droplets and color LED pixels raised by the plurality of embedded actuation electrodes, and wherein a subset of three or more actuation electrodes within the plurality of embedded actuation electrodes are aligned vertically, and wherein a single actuation electrode within the subset is closed while all other electrodes in the subset are open, and wherein each microfluidic droplet is set beneath a color LED pixel.
A computer program product, the computer program product comprising:
- one or more computer-readable tangible storage medium and program instructions stored on at least one of the one or more tangible storage medium, the program instructions executable by a processor capable of performing a method, the method comprising:
- receiving a plurality of media;
- translating one or more visual elements of the received plurality of media to braille;
- and
- generating a plurality of protrusions, each raised to a preconfigured height on a surface of a stretchable display screen by a plurality of embedded actuation electrodes, corresponding to the one or more translated visual elements using microfluidic actuation, wherein the plurality of protrusions are generated by a plurality of microfluidic droplets and color LED pixels raised by the plurality of embedded actuation electrodes, and wherein a subset of three or more actuation electrodes within the plurality of embedded actuation electrodes are aligned vertically, and wherein a single actuation electrode within the subset is closed while all other electrodes in the subset are open, and wherein each microfluidic droplet is set beneath a color LED pixel.
