This study adopted a Kansei engineering methodology to examine users’ Kansei values toward automotive interior designs by conducting experiments under two models: sensory experience and perceived value evaluation models. In the sensory experience model, 60 participants were recruited to experience using 27 vehicle samples and to assign scores to eight Kansei keywords. Hayashi's quantification theory type 1 was used to calculate the weight of 12 interior space items and 40 interior design categories. In the perceived value evaluation model, 60 participants completed a questionnaire on the influence levels of the Kansei keywords on their Kansei values from the perspectives of four consumer perceived value dimensions. The questionnaire scores were then evaluated using factor analysis to extract nine primary factors affecting participants’ perceptions. This study determined that the interesting and dynamic perceptions corresponded to five design items under the Excitement Quality factors, vigorous and recreational perceptions corresponded to four items under the Relaxation and Comfort factor, and technological and luxurious perceptions corresponded to six items under the Luxury and Splendor factor and the Esteemed Image factor. These findings can help designers and researchers in the relevant sectors create automotive interior designs that fulfill the expectations of users.
Based on sensory integration theory, six fabric samples containing tactile and visual stimuli were selected using the sensory perceptions of designers and combined with balls. Experiments involving these toys were implemented with 15 families with preschool-aged high-functioning autistic children. The results showed that (a) loose sequin (No. 15), which possessed equal tactile and visual intensities, was strongly correlated with frequent smiling/laughing and high enjoyment levels. The fabric provided a loose tactile sensation regarding surface interweave uniformity and a bright visual sensation regarding visually perceived luster; (b) suede (No. 5) exhibited a greater tactile intensity than visual intensity and was correlated with eye contact and activity response. This fabric possessed a smooth visual sensation regarding visually perceived smoothness; and (c) loose sequin (No. 15), which possessed equal tactile and visual intensities, was highly correlated with finger pointing and initiation. This fabric offered a thin tactile sensation regarding surface interweave thickness and a bright visual sensation regarding visually perceived luster. We suggest applying fabrics to composite toys. Specifically, loose sequin can be used initially to encourage autistic children to interact; subsequently, suede can enable sustained parent-child interaction. The experimental results provide a reference for establishing an innovative toy-design method for autistic children. Keywords: autism; sensory integration theory; parent-child interaction; toys
A toy is a valuable medium for promoting parent-child interaction. This study selected six light-emitting or reflective materials to produce composite toy balls, and conducted tests on 15 families with preschool-aged high-functioning autistic children. Quantification method I analysis was employed in the study, and the experimental results indicated that (a) the metal ball (reflective and dynamic light) was the representative sample that elicited many smiles or laughs and much finger pointing as well as high levels of pleasure and activeness.; (b) the mitball (static light) was the representative sample that provoked much eye contact, produced satisfactory reactions to activities,; (c) the quality of fluorescence enhanced the levels of pleasure and the reactions to the activity. We propose that dynamic and reflective materials can be adopted to divert the attention of children, and fluorescent toys can then employed to sustain parent-child interaction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
