Most interactive touchscreen kiosks are a challenge to accessibility: if graphics and sound fail in communication, the interaction process halts. In such a case, turning to the only remaining environmentally suited sense - the touch - is an intuitive option.
To reinforce the interaction with interactive touchscreen kiosks it is possible to add haptic (touchable) feedback into the features of the device. The range of touchscreen-suited haptic technologies already enables some touch feedback from touchscreen surfaces and significant leaps still forward are being made at a constant rate. Due to this development it is relevant to review the human-centred factors affecting the design of haptic touchscreen in public kiosks.
This thesis offers an overview for designing haptic clues for touchscreen kiosks. It emphasizes context sensitivity and the meaningfulness and communicability of different haptic design variants. As the main contribution, this thesis collects together the important considerations for the conscious design of haptic features in interactive kiosks and offers points of multimodal design considerations for designers intending to enrich their touchscreen interaction with haptic features
