This prototype was developed within one day and is therefore not meant to be perfect. The design is derived from BrailleWriters. Inspired by the use of Tactile Braille by Dr. Satoru Fukushima for communication, this prototype allows normal writing (e.g. to a sighted person) but also reading of messages. Each message for reading is split into its single characters. Each character has its specific arrangement in Braille (see Braille ASCII) and hence, also on the BrailleWriter-keyboard. The according keys start vibrating for each letter to deliver the message. This device could support deafblind people in distance communication or communication with people that are not trained in Braille.
I would like to thank Lisa Loh. Her workshop about “Understanding Deafblindness” at SADeaf (The Singapore Association For The Deaf) has inspired me to built this prototype.
