The Presentation is a summary of a study which proposed a predictive technology for seat hugging feel 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. R2 = 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.
