Demonstrating Interaction: The Case of Assistive Technology

Technology “demos” have become a staple in technology design practice, especially for showcasing prototypes or systems. However, demonstrations are also commonplace and multifaceted phenomena everyday life, thus found their way into empirical research of use. In spite presence HCI, methodical character as tool has so far received little attention our community. We analysed 102 video-recorded performed by visually impaired people, captured the context larger ethnographic study investigating doing so, we exhibit core features demonstrational work discuss relevance meta-activities occurring around within demonstrations. reflect on value an approach to HCI assistive technologies (AT), enabling shared understanding letting us identify opportunities design. Lastly, implications instrument accessibility more broadly.
