Objective: To determine whether response-effect (R-E) compatibility or stimulus-response (S-R) compatibility is more critical for touchless gesture responses. Background: Content on displays can be moved in the same direction (S-R incompatible but R-E compatible) or opposite direction (S-R compatible but R-E incompatible) as the touchless gesture that produces the movement. Previous studies suggested that it is easier to produce a button-press response when it is R-E compatible (and S-R incompatible). However, whether this R-E compatibility effect also occurs for touchless gesture responses is unknown. Method: Experiments 1 and 2 employed an R-E compatibility manipulation in which participants made responses with an upward or downward touchless gesture that resulted in the display content moving in the same (compatible) or opposite (incompatible) direction. Experiment 3 employed an S-R compatibility manipulation in which the stimulus occurred at the upper or lower location on the screen. Results: Overall, only negligible influences of R-E compatibility on performing the touchless gestures were observed (in contrast to button-press responses), whereas S-R compatibility heavily affected the gestural responses. Conclusion: The R-E compatibility obtained in many previous studies with various types of responses appears not to hold for touchless gestures as responses. Application: The results suggest that in the design of touchless interfaces, unique factors may contribute to determining which mappings of gesture and display movements are preferred by users.
