The interaction between tactile form and background design on taste perception.

摘要: There are plenty of studies showing the importance packaging when it comes to taste experience and product evaluation. However, there is still little known about how touch and vision interact to impact perception. This study builds forth on previous research, which shows that packaging structure can have influence perception food beverages. The present study implements 3D-printing technology develop cups; one smooth angular tactile form in order to represent sweet soft, sour strong tastes respectively. research investigates the impact these forms combination with background stimuli poster design as a function type (the ice-cream flavour vanilla lemon). Pre-testing showed was linked rounded shapes while lemon to sharp shapes. For main study, participants were seated front and asked try flavours from manufactured cups. They then evaluate flavour on concepts such sweetness, sourness, softness sharpness. Results showed smooth tactile increased perceived taste intensity. Furthermore, although congruency result in more favourable outcomes, incongruence (e.g. tasting cup while being shown poster) lead higher ratings liking some cases impacted evaluation favourably.
