Abstract
When multiple fingertips experience force sensations during movement, how does the brain decide whether to interpret the forces separately or as an integrated whole? To investigate this question, a force feedback device was used to display forces to two fingertips as they moved collinearly. The force patterns on each finger were constructed to produce illusory virtual bumps, and the distance between these bumps was varied across trials. When bump and finger spacing were identical, subjects tended to report only one bump. This result suggests that the brain selects interpretations of touch sensations that rely on the fewest coincidental alignments between the fingertips and environmental features. This result also has significance for the design of advanced multitouch displays with haptic feedback.

In particular, under what conditions are the sensations perceived as separate or, alternatively, as an integrated whole? In this work, we used a custom force-feedback device to display force signals to two fingertips (index finger and thumb) as they traveled along collinear paths. Each finger experienced a pattern of forces that, taken individually, produced illusory virtual bumps, and subjects reported whether they felt zero, one, or two bumps. We varied the spatial separation between these bump-like force-feedback regions, from being much greater than the finger span to nearly exactly the finger span. When the bump spacing was the same as the finger span, subjects tended to report only one bump. We found that the results are consistent with a quantitative model of perception in which the brain selects a structural interpretation of force signals that relies on minimizing coincidence stemming from accidental alignments between fingertips and inferred surface structures.</p></abstract><kwd-group><kwd>surface haptic</kwd><kwd>perception</kwd><kwd>touch</kwd><kwd>bumps</kwd><kwd>kinesthetic</kwd></kwd-group><funding-group><award-group id="gs1"><funding-source id="sp1">National Science Foundation (NSF)<named-content content-type="funder-id">100000001</named-content></funding-source><award-id rid="sp1">IIS-0964075</award-id></award-group></funding-group><counts><page-count count="6"></page-count></counts></article-meta></front></pmc><affiliations><list></list><tree><noCountry><name sortKey="Colgate, James Edward" sort="Colgate, James Edward" uniqKey="Colgate J" first="James Edward" last="Colgate">James Edward Colgate</name><name sortKey="Klatzky, Roberta L" sort="Klatzky, Roberta L" uniqKey="Klatzky R" first="Roberta L." last="Klatzky">Roberta L.
