With the continuous changes of the Internet environment and the birth of new technologies such as the Internet of Things and cloud computing,the design discipline has not only become more diversified in horizontal development,but also gradually deepened and subdivided in vertical research,especially in the field of interaction design.The design thinking based on user senses and experience is valued and highlighted in the field of interaction design with the constantly changing of interactive products and the interactive environment,as well as the increasing interaction needs of users.At present,interaction design is going through a transitional period.Graphical user interface(GUI)is still widely used,so users still need to learn new operation modes and interface languages when they contact with new products and functions.At the moment,communication between people and systems is a kind of non-natural-interaction with "sensory deficiency" and "behavior limitation",It is still applicable when dealing with the relationship between users and individual intelligent products,however,in the face of adapting to increasingly complex service systems,it is obvious that the existing GUI has great limitations.Therefore,the concept of "natural interaction" has been proposed,it is different from the GUI that users accept passively,natural interaction emphasizes the initiative and enthusiasm of user participation,and considers to optimize the emotion and experience between users and objects,it is suitable for the future interactive environment and it is also what users want to achieve.However,there are still some problems and limitations in the current research on natural interaction.As an extension of interaction design,it is still in the stage of exploration and attempt,and lacks of the output of systematic theoretical methods and design strategies.Smart home is the research background of this paper,and is a typical new generation of interactive objects in the future,the complexity and functional diversity of interactive system are suitable for the intervention and exploration of natural interaction design.The article clarifies the definition and summarizes the characteristics of natural interaction design,and it summarizes initial application principles of natural interaction design based on the existing service content of smart home.Then the article introduces the concept of "early elderly"which is a special elderly group that transitions from middle-aged stage to old age,They have more experience in intelligent product interaction than current elderly,but also are facing the inevitable physiological and psychological effects brought by age,Therefore,Natural interaction will play a greater role in this group.The article firstly conducted a preliminary study on the "early elderly" from the initial investigation,depth interviews and family workshops,which aims to understand the attitudes of this group towards smart home and the pain points of existing interactions,and explore their needs for future interactions,then combine the research results and the characteristics of natural interaction design to output the final design strategies and guidelines,These guidelines not only meet the requirements of elderly,it will also be universal to all user groups,and ultimately become the general strategies which can provide a theoretical basis and practical reference for the related fields. |
