A methodology to introduce gesture-based interaction into existing consumer product

The continuous progress of interaction technologies reveals that we are witnessing a revolution that is leading to a redefinition of the concept of “user interface” and to the development of new ways to interact with the electronic devices of all sizes and capabilities. Current trends in research related to the Human-Machine Interaction (HMI) show a considerable interest toward gesture, motion-based and full-body based interactions. In this context, a User-Centered Design (UCD) methodology to implement these novel interaction paradigms into consumer products is proposed with the aim to improve its usability, intuitiveness and experience. A case study is used to validate the methodology and measure the achieved improvements in user performance.
