Is home-based webcam eye-tracking with older adults living with and without Alzheimer's disease feasible?

Home-based eye tracking studies using built-in webcams are typically conducted with younger people and incur long set-up times and a large number of calibration failures. We investigated the set-up time, number of calibration failures and issues faced by twelve older adults living with and without Alzheimer's disease during home-based eye tracking. We found that home-based eye tracking is feasible with set-up support and we provide recommendations for future studies of this nature.
