Computer based automatic finger and speech tracking system

På svenska

Author

  • Björn Breidegard

Summary, in English

This article presents the first technology ever for on-line registration and interactive and automatic analysis of

finger movements during tactile reading (Braille and tactile pictures). Interactive software has been developed for registration (with two cameras and a microphone), MPEG-2 video compression and storage on disk or DVD as well

as an Interactive Analysis Program to aid human analysis. An Automatic Finger Tracking System has been implemented which also semi-automatically tracks the reading aloud speech on the syllable level. This set of tools opens the way for large scale studies of blind people reading Braille or tactile images. It has been tested in a pilot project involving congenitally blind subjects reading texts and pictures.
