3DTouch: A wearable 3D input device with an optical sensor and a 9-DOF inertial measurement unit
We present 3DTouch, a novel 3D wearable input device worn on the fingertip
for 3D manipulation tasks. 3DTouch is designed to fill the missing gap of a 3D
input device that is self-contained, mobile, and universally working across
various 3D platforms. This paper presents a low-cost solution to designing and
implementing such a device. Our approach relies on relative positioning
technique using an optical laser sensor and a 9-DOF inertial measurement unit.
3DTouch is self-contained, and designed to universally work on various 3D
platforms. The device employs touch input for the benefits of passive haptic
feedback, and movement stability. On the other hand, with touch interaction,
3DTouch is conceptually less fatiguing to use over many hours than 3D spatial
input devices. We propose a set of 3D interaction techniques including
selection, translation, and rotation using 3DTouch. An evaluation also
demonstrates the device's tracking accuracy of 1.10 mm and 2.33 degrees for
subtle touch interaction in 3D space. Modular solutions like 3DTouch opens up a
whole new design space for interaction techniques to further develop on.Comment: 8 pages, 7 figure
DualStream: Spatially Sharing Selves and Surroundings using Mobile Devices and Augmented Reality
In-person human interaction relies on our spatial perception of each other
and our surroundings. Current remote communication tools partially address each
of these aspects. Video calls convey real user representations but without
spatial interactions. Augmented and Virtual Reality (AR/VR) experiences are
immersive and spatial but often use virtual environments and characters instead
of real-life representations. Bridging these gaps, we introduce DualStream, a
system for synchronous mobile AR remote communication that captures, streams,
and displays spatial representations of users and their surroundings.
DualStream supports transitions between user and environment representations
with different levels of visuospatial fidelity, as well as the creation of
persistent shared spaces using environment snapshots. We demonstrate how
DualStream can enable spatial communication in real-world contexts, and support
the creation of blended spaces for collaboration. A formative evaluation of
DualStream revealed that users valued the ability to interact spatially and
move between representations, and could see DualStream fitting into their own
remote communication practices in the near future. Drawing from these findings,
we discuss new opportunities for designing more widely accessible spatial
communication tools, centered around the mobile phone.Comment: 10 pages, 4 figures, 1 table; To appear in the proceedings of the
