Design and Evaluation of the Interface of Recreational Intelligent Escort Products

In the context of Internet Things (IoT), user interface has become main means interaction between and network system, increasing variety ways interacting with created many “digital problems” for elderly. order to explore preferences elderly people in using smart products help designers objectively rationally select design solutions, enhance experience naturalness process, motivate them actively participate life, this study proposes a new approach solution selection, which reduces subjectivity selection process. Firstly, was decomposed into 7 components, orthogonal experimental used calculate evaluation indexes correlation degree objects 18 typical finally preferred obtained. Secondly, conjoint analysis obtain importance that older users attached seven components their types elements. The research takes an companion robot as example. method enables optimization target problem how match elements final preference IoT systems, enabling use mathematical rational thinking contradictory problems, enhancing objectivity scientificity providing more natural comfortable users, promoting healthy ageing.
