Abstract

The sense of touch has been shown to convey emotive information and nuances in face-to-face interpersonal communication, but its applications in mobile communication technologies are still limited. One of the challenges for such new communication medium is the interpretation of tactile messages. This paper presents a study with an early prototype of a mobile tactile device. Twenty novice participants interpreted four messages consisting of a four-channel vibrotactile stimulus, complemented with three cumulative textual cues regarding 1) the communication setting, 2) sender, and 3) situation. The subjective interpretations were assessed with four semantic differential scales, and the reasoning behind the interpretations was inquired by interviewing. The findings show that the intensity and, to some degree, the friendliness of the message could be identified from the tactile-only message. However, to correctly interpret the degree of formality or emotionality in the message, also contextual cues were needed.
