Findings are presented from a user test of several different concepts to enable personal identification number (PIN) entry on a touchscreen by people who are blind or partially sighted. A repeated measures experimental design was used for the user test, with all participants using all concepts in a randomised order. Results are presented, and wider implications of this study and the subsequent approvals are discussed.
