GazeNoter: Co-Piloted AR Note-Taking via Gaze Selection of LLM Suggestions to Match Users' Intentions

Note-taking is critical during speeches and discussions, serving for later summarization and organization and for real-time question and opinion reminding in question-and-answer sessions or timely contributions in discussions. Manually typing on smartphones for note-taking could be distracting and increase cognitive l…

transPAF: Rendering Omnidirectional Impact Feedback with Dynamic Point of Application of Force All Round a Controller

Impact is common feedback on virtual reality (VR) controllers. It applies to different points of application of force (PAFs) and directions in varied scenarios, e.g., using a sword and pickaxe, stabbing and slashing with a sword, or balls flying and hitting a racket in different directions. Therefore, rendering dynami…

ELAXO : Rendering Versatile Resistive Force Feedback for Fingers Grasping and Twisting

Haptic feedback not only enhances immersion in virtual reality (VR) but also delivers experts’ haptic sensation tips in VR training, e.g., properly clamping a tenon and mortise joint or tightening a screw in the assembly of VR factory training, which could even improve the training performance. However, various and co…

FingerX: Rendering Haptic Shape of Virtual Objects Augmented from Real Objects using Extendable and Withdrawable Supports on Fingers

Interacting with not only virtual but also real objects, or even virtual objects augmented by real objects becomes a trend of virtual reality (VR) interactions and is common in augmented reality (AR). However, current haptic shape rendering devices generally focus on feedback of virtual objects, and require the users…

ImpactVest: Rendering Spatio-Temporal Multilevel Impact Force Feedback on Body in VR

Rendering instant and intense impact feedback on users’ hands, limbs and head to enhance realism in virtual reality (VR) has been proposed in previous works, but impact on the body is still less discussed. With the body’s large surface area to utilize, numerous impact patterns can be rendered in versatile VR applicati…

HairTouch: Providing Stiffness, Roughness and Surface Height Differences Using Reconfigurable Brush Hairs on a VR Controller

Tactile feedback is widely used to enhance realism in virtual reality (VR). When touching virtual objects, stiffness and roughness are common and obvious factors perceived by the users. Furthermore, when touching a surface with complicated surface structure, differences from not only stiffness and roughness but also s…

GuideBand: Intuitive 3D Multilevel Force Guidance on a Wristband in Virtual Reality

For haptic guidance, vibrotactile feedback is a commonly-used mechanism, but requires users to interpret its complicated patterns especially in 3D guidance, which is not intuitive and increases their mental effort. Furthermore, for haptic guidance in virtual reality (VR), not only guidance performance but also realism…

ElastiLinks: Force Feedback between VR Controllers with Dynamic Points of Application of Force

Force feedback is commonly used to enhance realism in virtual reality (VR). However, current works mainly focus on providing different force types or patterns, but do not investigate how a proper point of application of force (PAF), which means where the resultant force is applied to, affects users’ experience. For ex…

ElastOscillation: 3D Multilevel Force Feedback for Damped Oscillation on VR Controllers

Force feedback from damped oscillation is a common effect in our daily lives, especially when shaking an elastic object, an object hanging or containing other stuff, or a container with liquid, e.g., casting with a fishing pole or wine-swirling. Such a force, affected by complex physical variations and collisions, is…
