CHAPTER TWENTY - THREE · INTERVIEW WITH AKIHIRO SAITO ­ 23.3 The Two Objectives and Four Principles of Gamenics I think this is a good place for you to give an outline of gamenics theory. OK. Gamenics theory has two objectives: intuitive operability and gradual learning curve.

Operability that does not require a manual (designed so that users are not con- fused about what they can do) 3. Engaging choreography, gradual learning curve (devices that promote enthusiasm) 4. Beyond gaming (links things to reality so they seem real)
