Disclosing the secrets of braille reading: Computer-aided registration and interactive analysis

The pilot project reported here utilized the first technology ever developed for the computerized on-line registration and analysis of finger movements during Braille reading. Five congenitally blind subjects performed tactile reading of pedagogically carefully selected texts. Two specialists in visual impairments analyzed the computer-registered reading activities using specially designed interaction software. The subjects themselves were interviewed and contributed to discussions about their own individual reading styles. The analyses of this first handful of subjects reveal a number of important strategies and preferences with regard to on-line tactile reading. Further, the results challenge several assumptions and practices in Braille teaching. This pilot project lays the foundation for more comprehensive large-scale studies - both cross-sectional and longitudinal ones - studies long wanted in the domain of tactile reading.
