This document summarizes assistive technologies for individuals with spinal cord injuries. It describes traditional devices like keyboards, mice, trackballs, switches and pointers that use physical interaction. It also covers sound-based, tracking and myographic interfaces that respond to speech, head/eye movement or muscle signals. The document discusses various brain-computer interface approaches using EEG, MEG, fMRI and other neural signals. It evaluates different technologies based on factors like direct selection vs scanning input, speed, accuracy and acceptance. While many options exist, the document concludes that assistive technologies remain highly limited overall.
