哈喽!!

I'm Haopeng Wang

Ph.D. Student at Lancaster University

I’m working in the field of Human-Computer Interaction (HCI) as a part of the GEMINI ERC project, supervised by Prof. Hans Gellersen. I explore and design multimodal interaction techniques for virtual reality, leveraging coordination between eye, head, and hand to improve efficiency and user experience.

HeadDepth

Gaze, Wall, and Racket

Motion Correlation

Cone and Bubble

HeadShift

Saves head rotation needed for head pointing.

HeadShift

Aiming in VR bubble shooter game by just moving the head.

HeadShift

Saves head and neck effort in frequent vertical placement.

HeadShift

The technique covers a 360-degree horizontal range for head pointing while offering a precise alignment.

HeadDepth: Relative

Gaze raycasting with head pitch for depth control, with depth control speed reacting to head velocity.

HeadDepth: EdgeGain

Gaze raycasting with head pitch for depth control. Depth control speed is signficantly scaled up when eye-in-head angle is getting eccentric.

HeadDepth: Ping-pong

Gaze raycasting with head pitch for depth control. Each depth could be achived with multiple head pitch angle, with at least one also gives a comfortable angle for viewing.

HeadDepth

While operating with both hands, surgeons wearing an AR headset can navigate MRI images by tilting their head up and down.

HeadDepth

The user controls a 3D cursor using gaze for direction and head pitch for depth, enabling both virtual navigation and selection of 3D elements.

HeadDepth

The user controls a 3D cursor with gaze for direction and head pitch for depth, allowing them to pick up and reposition panels in 3D space.

HeadDepth

Gaze and head pitch control a 3D cursor for fast, rough 3 DoF positioning, with hands taking over for precise 6 DoF manipulation.

Gaze, Wall, and Racket

Gaze & Racket: selecting by intersecting the gaze ray with a hand-fixed plane.

Gaze, Wall, and Racket

Gaze & Wall: selecting by intersecting the gaze ray with a hand-controlled ground plane.

Gaze, Wall, and Racket

Hand & Racket: selecting by intersecting the hand ray with a hand-fixed plane on the other hand.

Gaze, Wall, and Racket

Hand & Wall: selecting by intersecting the hand ray with a ground plane controlled by the other hand.

Motion Correlation

Magic Finger: selecting a menu item that follows the fingertip by tracing with eyes.

Motion Correlation

Stretch Ruler: selecting a rotating menu item as hands move apart by tracing surrounding asteroids with eyes.

OnGazeLeave

Gaze Trigger: confirming hand selection with a saccade to a pop-up gaze target.

OnGazeLeave

Hands-free 2D Positioning: attach an object to the head pointer while the gaze is within its area, and release it when the gaze leaves.

OnGazeLeave

Hands-free Multi-target Selection: add the object to the selected object list when the gaze is first on the target and then the head pointer lands on the target.

Cone and Bubble

Gaze + Hand: gaze cone (green) intuitively filter out a subset of targets, allowing hand to perform more precise and easier selections.

Cone and Bubble

Hand + Hand: the hand cone (green) intuitively filter out a subset of targets in the cone, allowing the other hand to perform more precise and easier selections.

OnGazeLeave

Camera Dragging: when the gaze is fixated at the center of the viewport, the virtual forward direction shifts horizontally based on (draged by) head rotation.

Cone and Bubble

Voronoi Diagram: generate a voronoi diagram with targets located within a gaze cone, where target sizes are dynamically expanded to facilitate hand-based selection.

Small Bench

Moving object along a hand ray, with depth controlled via the trackpad on the opposite hand's controller, and rotation also manipulated by the other hand.

FishRod

Dynamic parabolic curve for ground-pointing, enabling natural selection at both close and far distances.
