Sensual Evaluation Instrument


This set of sculpted objects opens a rich new channel of communication between designers and users of technology. The SEI was created to support non-verbal self-report of emotion as an experience unfolds. Since their creation in 2006, they have been used in many research contexts and venues. In 2014, a workshop at CHI was held that built upon the principles of the SEI. The SEI objects are available as 3d files for download and printing. If you are interested in using them, please send an email to and we can provide the files.

Instructions for their use, and papers about their creation, can also be downloaded here:
