Evaluating TUI Design for Tacit Knowledge: Perceived Effects and Interface Efficiency in Woodworking

Capturing and communicating tacit knowledge remains a challenge for tangible interaction design. This project presents the third stage out of four of an educational interface evaluation for a tacit knowledge project in woodworking practices. It briefly covers earlier stages of the project, including sensing and interface design, before focusing on the evaluation (n= 14) of a customized block plane TUI. It argues from a sensing approach to the design and ultimately the feasibility of an educational interface for tacit knowledge. The evaluation combines SUS with soma-based approaches to capture a novel range of responses. The findings reveal how the interface fosters growing emotional engagement and shifting attention throughout the targeted woodworking practice. They demonstrate the value of soma-informed evaluation for tracking these temporal dynamics and point to future design directions for tacit knowledge interfaces.
