Students with visual impairment and blindness learn 3D shapes using physical models, which pose portability issues and high associated costs. Although tactile and kinesthetic feedback systems have been proposed for non-visual exploration of 3D virtual objects, such systems tend to suffer from similar shortcomings. In this research, we propose TMOVE, a low-cost handheld tactile feedback actuator to provide tactile, vibrotactile, and combined feedback for the exploration of virtual space. We conducted a preliminary study with 10 blindfolded sighted participants to compare the perceived 3D experience and the effectiveness of using the feedback modalities in the exploration of two coplanar virtual line segments. We found that all the feedback modalities are equally effective in the exploration of virtual space, and multimodal feedback offers an enhanced 3D perception of virtual objects. We believe the findings presented in this paper will be helpful for designers and researchers in developing low-cost tactile feedback systems. © 2020 Association for Computing Machinery.
