A product is chosen by users not only for the features it offers but also for the perceived experience of use. This statement widely recognized in literature highlight that key issues for the success of interactive products are the practical, experiential, affective, meaningful and valuable aspects of interaction.
In the last years, gesture-based interfaces have been introduced to make the experience of interaction more emotional, intuitive and natural. For this reason, the design and development of products integrated gesture-based interfaces represent a challenging issue.
In this context, a User-Centered Design (UCD) method to implement novel interaction paradigms into traditional consumer products is proposed. Its application in a real case study addresses the development and prototyping of a system exploiting gesture-based interaction to train aspiring conductors of orchestra. If a young musician wants to play a guitar, it is usually no great problem to find one, but if a musician wants to learn the ins and outs of being a conductor, the problem shifts to search for an electronic device managed by hands as used by conductors. The developed system provides three main functionalities: tempo control, velocity control and instruments activation. It represents both a use case to validate the proposed UCD method and an innovative solution in the context of aspiring conductor’s training.Copyright © 2016 by ASME
