Sensual Evaluation Instrument (SEI)


This tool is a set of sculpted objects that can be held in the hand, used by a person to indicate how they are feeling as they interact with a system designed to evoke affect. The objects are meant to provide a flexible, non-verbal channel of communication between user and designer during system development. Because they do not use language, we also hope the objects will be easy to use in many cultural contexts.
