Abstract
The operating feeling of rotary switches used in various in-vehicle equipment influences our impression of the vehicle itself. Thus, the operating feeling needs designing appropriately by understanding the correspondence with the relevant physical characteristics. This study evaluated the onomatopoeic free-answer and the semantic differential method using adjectives for operating feeling of rotary switches, which consists of tactile and auditory stimuli. Two experimental results showed the relationship between phonological characteristics of onomatopoeia, adjectival expressions, and physical characteristics of stimuli, respectively. Moreover, we indicated the features of onomatopoeic and adjectival expressions in the design of the operating feeling consisting of multimodal stimuli.
