ABSTRACT
This papcr discusses the etlectiveness of haptics or tactile interaction on touch screens for univcrsal communication during an cmergcncy or while travcling. The original idea was proposed by deaf people for communicating in an emergency, such as a disaster or accident situation. Thc solution consists of simple menu-like metaphors implemcnted on cards or on rcmote terminal cquipment display of a public terminal unit. Prcvious research rcsults showed that using cards shortened thc time needed to communicate symptoms by 30%. This Universal Communication Card can be then used not only by deaf people but also by universal users such as foreigners.Human Centred Design is the underlying concept behind this research. It compares cards and remote tcrminal equipmcnt display like iPhone. Assessors cvaluated from thc perspective of tactile sense applying originally designed Marble method and Multivariate Analysis. The results showed the remote terminal equipment display to be more favorable compared to cards in that it is quicker to reach thc target card and back to the homepage. This is particularly useful when traveling.
