An Embodiment Perspective of Affective Touch Behaviour in Experiencing Digital Textiles

Handling textiles is not only a semantic experience, but also an emotional one. Whilst handling a textile is crucial for its appreciation and understanding, this channel is still little explored in the digital realm, where focus has been given to the haptic feedback aspect of handling. In this paper, we discuss the importance of touch behaviour in interactive digital handling to allow people to explore, emotionally engage with and understand textile properties. We build on our findings from previous studies, where we investigated how people handle fabrics in real-life situations and more generally how their touch behaviour may affect the experience, relating it to literature from textile, HCI, embodied cognition and embodied affect to discuss how current technology should develop to provide a more realistic touch experience. Additionally, we consider how crowd sourcing of the textile experience could be extended by taking into account non-verbal expressions of textile-handling experience. We show that further knowledge is needed to design interactive technology that supports active and unconstrained touch, as well as the affective aspects of experience.

The tactile triangle: a design research framework demonstrated through tactile comparisons of textile materials

Tactile experiences of textile materials are difficult to communicate and elicit. To interrogate this space we propose the tactile triangle, a framework to facilitate systematic analysis and comparison of tactile experiences. The three levels reflect different aspects of tactile experience and possible methods to capture them: physical properties, in which human senses or objective testing measure fabric properties; the perceptual space level in which triadic comparisons reveal combinations of various dimensions which capture and describe tactile experiences; and finally the communication level, in which design games elicit languages communicating tactile perceptions. A case study illustrates the frameworks use to compare the tactile experiences of textiles in experts and consumers. The results show expert and consumer perceptions overlapped and correlated well to objective measures except in the perception of temperature. We conclude by discussing the frameworks effectiveness, the contribution of individual methods, and its potential as a communication tool for designers.
