Development of a Predictive Technology for Seat Emotion Based on Sitting Body Pressure: Focused on Hugging Feel

摘要

The present study proposed a predictive technology for seat hugging feels using sitting body pressure on virtual environment. To develop a seat hugging feel prediction system, a five-step ergonomic research was conducted: S1 feasibility study, S2. hugging quantification, S3, hugging experiment, S4. hugging analysis, and S5. hugging evaluation system development. Pressure appearance ratio (PAE) and pressure appearance unevenness (PAUE) of mid-back and side were found significant (adj R~2 = 73%) on seat hugging feels. A statistical equation for quantifying hugging feels was developed and embedded into a seat emotion prediction system. The proposed system can contribute to efficient and quantitative seat development.
