MobiSweep

Abstract

In this paper, we explore quick 3D shape composition during early-phase spatial design ideation. Our approach is to re-purpose a smartphone as a hand-held reference plane for creating, modifying, and manipulating 3D sweep surfaces. We implemented MobiSweep, a prototype application to explore a new design space of constrained spatial interactions that combine direct orientation control with indirect position control via well-established multi-touch gestures. MobiSweep leverages kinesthetically aware interactions for the creation of a sweep surface without explicit position tracking. The design concepts generated by users, in conjunction with their feedback, demonstrate the potential of such interactions in enabling spatial ideation.

“…While we explored its use in a controlled-setting, it can also be explored in situations where users are on-the-move. Finally, we foresee that our work could allow other researchers to extend upon their very recent and interesting approaches; for instance, it could be used in collaborative 3D object manipulation [19], spatial design ideation [57] or cross-device interaction scenarios [42], which are currently limited by the use of 3DoF input-devices.…”

“…With the Inertial Measurement Unit (IMU), phone-orientation (3DoF) has been used to point at distant screens [11,15,44,50] and in VR [16,32] via ray-casting. The IMU has furthermore been used for the selection and manipulation of objects in 3D environments via 2D rotational planes [19,29,45,53,57], for enabling throw-or swing gestures to transfer media between devices [14,42], and for uni-stroke letter [1] or symbol [30,63] recognition in combination with acceleration data.…”
