Usability Evaluation of VR Shopping System not Imitating Real Stores
Ikumi Hisamatsu, Yuji Sakamoto · 2023
Virtual reality (VR) shopping has been attracting attention for its potential to offer people a new purchasing experience. However, most previous studies on VR shopping have dealt with systems that imitate real stores. Therefore, we focused on VR shopping systems that do not imitate real stores (non-store type systems) and evaluated their usability.First, we conducted an experiment to compare the shopping experience between a store type system and a circularly displayed non-store type system. The results revealed that the non-store type system was superior in terms of usefulness and ease of mobility but inferior in terms of spatial recognition and likability. On the basis of these results, we then proposed a retractable non-store type system and conducted an experiment to clarify its usability. As a result, the retractable non-store type system was rated better in terms of visibility and ease of mobility than the store type system. To create a better system, we have fixed and improved some problems with the retractable system pointed out by the experiment participants.
