Extending and shortening a real rod using AR and DR techniques, respectively. a) a physical rod with 6DoF sensor (a Polhemus Fastrak receiver), b) the user with a VST-HMD tracked in 6DoF gazes at the rod and waves the rod at every constant time interval. c) 160% length rod with AR, d) 100% length rod with a texture overlay, and e) 30% length rod with DR.

Abstract We can use augmented reality (AR) and diminished reality (DR) in combination, in practice. However, to the best of our knowledge, there is no research on the validation of the cross-modal effects in AR and DR. Our research interest here is to investigate how this continuous visual changes between AR and DR would change our weight sensation of an object. In this paper, we built a system that can continuously extend and reduce the amount of visual entity of real objects using AR and DR renderings to confirm that users can perceive things heavier and lighter than they actually are in the same manner as SWI. Different from the existing research where either AR or DR visual effects were used, we validated one of cross-modal effects in the context of both continuous AR and DR visuo-haptic. Regarding the weight sensation, we found that such cross-modal effect can be approximated with a continuous linear relationship between the weight and length of real objects. Our experimental results suggested that the weight sensation is closely related to the positions of the center of gravity (CoG) and perceived CoG positions lie within the object’s entity under the examined conditions.
