Visual communication of how fabrics feel

Although product photos and movies are abundantly present in online shopping environments, little is known about how much of the real product experience they capture. While previous studies have shown that movies or interactive imagery give users the impression that these communication forms are more effective, there are no studies addressing...

Cross-modal visuo-haptic mental rotation: Comparing objects between senses

The simple experience of a coherent percept while looking and touching an object conceals an intriguing issue: different senses encode and compare information in different modality-specific reference frames. We addressed this problem in a cross-modal visuo-haptic mental rotation task. Two objects in various orientations were presented at the...

Haptic perception disambiguates visual perception of 3D shape

We studied the influence of haptics on visual perception of three-dimensional shape. Observers were shown pictures of an oblate spheroid in two different orientations. A gauge-figure task was used to measure their perception of the global shape. In the first two sessions only vision was used. The results showed that observers made large errors...

Haptics disambiguates vision in the perception of pictorial relief

In this study we demonstrate that touch decreases the ambiguity in a visual image. It has been previously found that visual perception of three-dimensional shape is subject to certain variations. These variations can be described by the affine transformation. While the visual system thus seems unable to capture the Euclidean structure of a shape...
