This paper outlines the design and evaluation of a haptic interface intended to convey non audio-visual directions to an ATM (Automated Teller Machine) user. The haptic user interface is incorporated into an ATM test apparatus on the keypad. The system adopts a well known 'clock face' metaphor and is designed to provide haptic prompts to the user in the form of directions to the current active device, e.g. card reader or cash dispenser. Results of an evaluation of the device are reported that indicate that users with varying levels of visual impairment are able to appropriately detect, distinguish and act on the prompts given to them by the haptic keypad. As well as reporting on how participants performed in the evaluation we also report the results of a semi structured interview designed to find out how acceptable participants found the technology for use on a cash machine. As a further contribution the paper also presents observations on how participants place their hands on the haptic device and compare this with their performance.
