Perception of products by progressive multisensory integration. A study on hammers

Area of Science:

• Product design and human-computer interaction.
• Consumer behavior and perception studies.
• Ergonomics and usability engineering.

Background:

• Emotional design principles are increasingly applied to commercial products.
• Understanding the impact of sensory integration on product perception is crucial for effective design.
• Previous studies often focused on digital interfaces, leaving a gap in understanding physical product interaction.

Purpose of the Study:

• To investigate how multisensory (visual-haptic) integration affects product perception.
• To determine the influence of varying interaction levels (from viewing photos to physical use) on perceived product attributes.
• To assess the applicability of emotional design studies to common commercial products like hammers.

Main Methods:

• Utilized a hammer as the experimental product to bridge emotional design and commercial applications.
• Collected subjective user opinions through semantic differential tests.
• Employed factor analysis to identify key semantic dimensions of product perception.

Main Results:

• Identified six semantic factors: Quality/Robustness, Ergonomics/Appearance, Innovation, Lightness, Dynamic Effects, and Efficacy.
• Perceptions of Lightness and Dynamic Effects were highly sensitive to the level of interaction.
• Ergonomics/Appearance was partially affected by interaction, while Innovation, Quality/Robustness, and Efficacy were detectable even from lower interaction levels (e.g., photographs).

Conclusions:

• Commercial products are sensitive to emotional design principles.
• Multisensory integration significantly enhances the perception of factors directly related to physical interaction (Ergonomics/Appearance, Lightness, Dynamic Effects).
• Certain ergonomic aspects and ease-of-use perceptions can be detected at various interaction stages, even before direct physical engagement.
