Exploratory study — gesture-based control in handheld tools
This project investigated how tool geometry and weight distribution influence gesture, precision, and user control during repetitive everyday actions.
The study focused on a handheld seasoning tool designed to be operated through a controlled shaking motion, examining how elongation, mass placement, and grip profile affect accuracy and fatigue. Prototypes were used to evaluate how users naturally translate arm and wrist movement into consistent dispensing behavior.
Key aspects explored included:
-
the relationship between weight distribution and motion control
-
ergonomics of elongated handles during repeated use
-
how form can guide intuitive gestures without mechanical complexity
The project is presented as applied research into how physical design can structure user behavior and improve precision in simple, low-tech tools.
