At a glance

Does adding virtual tactile locations increase the information a torso display can communicate?

Measuring how accurately people identify horizontal and vertical tactile locations, and what happens when illusory stimuli double the available positions.

Torso displaySpatial resolutionPerceptual study

The approach

Two absolute-identification experiments compare azimuth and elevation. Physical actuators provide real stimuli, and the funneling illusion adds intermediate locations.

Key takeaways

  1. Reliable physical locations

    Identification accuracy exceeds 95.6% when physical stimuli represent six to eight directions.

  2. A resolution–accuracy trade-off

    Doubling the spatial resolution with illusory stimuli reduces accuracy to 74.1–77.8%.

  3. More locations do not guarantee more information

    Estimated information transfer remains similar across conditions, informing the design of torso-based navigation cues.
