Investigating Single-Handed Microgesture Scrolling Techniques

Scrolling is ubiquitous in our daily computing experience. We explore how single-handed microgestures can be used for scrolling. Based on an analysis of the basic components necessary for scrolling, we selected 3 microgestures: Tap, Hold and Drag. Considering both rate and position controls, we designed 4 microgest…

Visualization of Tracking Uncertainty in AR-based Surgical Guidance

Uncertainty caused by instrument tracking errors affects critical tasks such as surgery assisted by Augmented Reality (AR) guidance. This work investigates whether visualizing such uncertainty can improve task performance, trust, and confidence. We present four visualization techniques: Cone, Circle, Gauge, and Color.…

Efficient Finger Model and Accurate Tracking for Hover-and-Touch, Mid-air and Microgesture Interaction

Bare-handed gestural interaction with computer systems is widespread, whether with touchscreens or Augmented Reality headsets. Various forms of gestural interaction exist including hover-and-touch, mid-air and microgesture interaction. Studying the full benefits of these gestural interactions, and their combinations,…

An Evaluation of Spatial Anchoring to position AR Guidance in Arthroscopic Surgery

This work examines spatial anchoring strategies to position augmented reality guidance during surgery. We consider three strategies: anchoring to the Patient, the surgical Tool, and the Surgeon's head. These strategies were evaluated in a first experiment involving 24 non-professional participants, using two guidance…

Studying the Simultaneous Visual Representation of Microgestures

Hand microgestures are promising for mobile interaction with wearable devices. However, they will not be adopted if practitioners cannot communicate to users the microgestures associated with the commands of their applications. This requires unambiguous representations that simultaneously shows the multiple microge…

µGlyph: a Microgesture Notation

In the active field of hand microgestures, microgesture descriptions are typically expressed informally and are accompanied by images, leading to ambiguities and contradictions. An important step in moving the field forward is a rigorous basis for precisely describing, comparing, and analyzing microgestures. Towards t…

PickCells: A Physically Reconfigurable Cell-composed Touchscreen

Touchscreens are the predominant medium for interactions with digital services; however, their current fixed form factor narrows the scope for rich physical interactions by limiting interaction possibilities to a single, planar surface. In this paper we introduce the concept of PickCells, a fully re-configurable devic…
