| Abstract Touchscreens on self-service terminals such as ATMs (automated teller machines) can be difficult to use for people with visual impairment. In this paper we present a study developing gestural interaction methods to be used for entering the Personal Identification Number (PIN), which is a particularly challenging task as there are additional security requirements prohibiting most auditory feedback. After initial concept development, four PIN entry concepts were evaluated with visually impaired users. The concept with tactile features was found to provide significant benefits: a fixed tactile reference point for orientation as well as added support for people unfamiliar with touchscreen interaction. |
