Text Entry

The process of entering text into a computer or communication device, encompassing the full range of input methods from standard keyboards to alternative approaches used in assistive technology such as on-screen keyboards, word prediction, scanning, switch-based input, eye tracking, head pointing, and brain-computer interfaces. Text entry rate — typically measured in words per minute — is a key metric in evaluating assistive technology effectiveness. For people with motor impairments, text entry is often the primary bottleneck in computer access and communication, making optimization of input methods critical for functional independence.
