We explore the use of multimodal input to predict the landing position of a ray pointer while selecting targets in a virtual reality (VR) environment. We first extend a prior 2D Kinematic Template Matching technique to include head movements. This new ...

Large curved displays are becoming increasingly popular due to their ability to provide users with a wider field of view and a more immersive experience compared to flat displays. Current interaction techniques for large curved displays often assume a ...

This study investigates the effect of Lift-off Distance (LoD) on a computer mouse, which refers to the height at which a mouse sensor stops tracking when lifted off the surface. Although a low LoD is generally preferred to avoid unintentional cursor ...

Head pointing is widely used for hands-free input in head-mounted displays (HMDs). The primary role of head movement in an HMD is to control the viewport based on absolute mapping of head rotation to the 3D environment. Head pointing is conventionally ...

This study investigates the effect of Lift-off Distance (LoD) on a computer mouse, which refers to the height at which a mouse sensor stops tracking. Although a low LoD is generally preferred to avoid unintended cursor movement in mouse lifting (=...

Computer mice are widely used today as the primary input device in competitive video games. If a player exhibits more wrist rotation than other players when moving the mouse laterally, the player is said to have stronger wrist-aiming habits. Despite ...

Diagrams often appear as node-link representations in contexts such as taxonomies, mind maps and networks in textbooks. Despite their pervasiveness, they present accessibility challenges for blind and low-vision people. To address this challenge, we ...

Gaze-assisted interaction techniques enable intuitive selections without requiring manual pointing but can result in unintended selections, known as Midas touch. A confirmation trigger eliminates this issue but requires additional physical and conscious ...

Head-based pointing is an effective interface for those with limited hand control, though it may involve a learning curve due to discrepancies between desired pointer movement and actual system response to head motion. We theorize that individuals have ...

• An optimal Dual-Thumb technique outperforms Single-Thumb pointing techniques.
• Similar usage of both thumbs improves the pointing efficiency.
• Relative pointing for the coarse step improves the efficiency.
• Two thumbs are better ...

Tablets are often used as a distant input device to interact with large displays. Users can hold the tablet with two hands when interacting for a long time to avoid fatigue or dropping it. Still, most previous distant interaction techniques ...

The rapid advancement of the automotive industry towards automated and semi-automated vehicles has rendered traditional methods of vehicle interaction, such as touch-based and voice command systems, inadequate for a widening range of non-driving related ...

This study investigated how displaying an AI attention heatmap influences human acceptance of the AI’s suggestions in accordance with the interpretability of the heatmap. We conducted an experiment using a visual task where the participants were ...

The use of virtual reality (VR) system has become more common with the arrival of a new generation of headsets. This increase in accessibility has in turn led to VR being used for applications which require longer sessions, such as ...

• Study of the effects of hand synchronization on users’ perceived arm fatigue in VR.

Pointing is a ubiquitous part of human communication. However, pointing gestures to distal referents are often misunderstood systematically, which may limit the usefulness of pointing. We examined pointing-based communication in a collaborative ...

Text selection is a required step prior to performing many text editing tasks like copy or cut. Text selection relying on adjustment handles is a widely adopted method on touchscreen mobile devices. However, this method has limitations ...

• This study proposes Text Pin, a novel text selection technique for direct-finger touch interactions.

This study investigated a “hand cursor” technique which used an open hand to control an area cursor (i.e., a cursor with a larger active area) while using an index finger extended gesture to switch the area cursor into a point cursor (i.e., a ...

With the recently increasing capabilities of modern vehicles, novel approaches for interaction emerged that go beyond traditional touch-based and voice command approaches. Therefore, hand gestures, head pose, eye gaze, and speech have been extensively ...

Research in service robotics strives at having a positive impact on people’s quality of life by the introduction of robotic helpers for everyday activities. From this ambition arises the need of enabling natural communication between robots and ...

In this work, we propose MultiFingerBubble, a new variation of the 3D Bubble Cursor. The 3D Bubble Cursor is sensitive to distractors in dense environments: the volume selection resizes to snap-to nearby targets. To prevent the cursor to constantly re-...

Current pointing techniques provide no adequate way to select very small objects whose movements are fast and unpredictable, and theoretical tools –such as Fitts’ law– do not model unpredictable motion. To inform the design of appropriate ...
