A study of immersive technology for product usability improvement design based on comprehensive value evaluation

The combined value of any product design method depends on the design benefits and costs of use, determining the need to put the method into practice. In this study, a virtual reality design system was constructed to support the widely adopted user interview method for the usability improvement design of an existing product, using an industrial remote control as example. The combined value of the method was verified to be superior to the use of user interviews alone, in terms of the number and importance of usability questions mined by users, the level of styling of improved design solutions guided by usability questions, and the willingness of designers to use the method. It provides a useful reference for the promotion of immersive technology in the field of product design and the search for new focus points.
