“…Geometric models are used to represent the 3D shape of the virtual hand, and geometric constraints of the palm and multiple fingers. Each element of the virtual hand can be represented by using mainstream discrete models, e.g., mesh model [16]- [23], voxel model [24], [25], point-shell model [26], [27], and sphere model [28] [29]. The mesh model (such as Fig.…”

Interacting with virtual objects with haptic feedback directly using the user's hand (hand-based haptic interaction) has attracted increasing attention. Due to the high degrees of freedom of the hand, compared with tool-based interactive simulation using a pen-like haptic proxy, hand-based haptic simulation faces greater challenges, mainly including higher motion mapping and modeling difficulty of deformable hand avatars, higher computational complexity of contact dynamics, and nontrivial multi-modal fusion feedback. In this paper, we aim to review key computing components for hand-based haptic simulation, and draw out major findings in this direction while analyzing the gaps toward immersive and natural hand-based haptic interaction. To this end, we investigate existing relevant studies on hand-based interaction with kinesthetic and/or cutaneous display in terms of virtual hand modeling, hand-based haptic rendering, and visuohaptic fusion feedback. By identifying current challenges, we finally highlight future perspectives in this field.

“…For virtual hand interaction, the intersection of ray and distance calculation became the means of detecting the collision [9]. Wan implemented the collision detection of the virtual hand by dividing it into simple geometric objects by the package RAPID [10]. Besides these geometric methods, algebraic intersections using matrix methods were also introduced to solve the intersection problems of parametric and algebraic curves [11].…”

Virtual hand usually simulates human hands by mapping the actual shapes of hands to virtual environment and modeling the hand-object manipulations in human machine interactions. For describing virtual hand and its manipulation in a unified framework, a method based on conformal geometric algebra (CGA) is proposed to solve the problems of virtual hand modeling and interaction in this paper. With the vertex blending based on CGA, the artifacts on the finger joints are improved, which enhances the realism of the virtual hand model. With the same tool, the collision detection between the virtual hand and the manipulated objects is implemented. The gesture of grasp, pinch, and hold are recognized, and the corresponding manipulation rules are established by CGA calculation. To test these three typical manipulations, the manipulated objects are imported and the manipulation effectiveness is evaluated.

“…However, the high computational burden makes its application for interactive virtual environments difficult. In [11], a 4-layer flexible virtual hand model was proposed for virtual hand haptic interaction. The skin layer, kinematics layer, collision detection layer and haptic layer are integrated into a virtual hand to simulate the natural anatomy of the human hand in its appearance and motion, and more important, to reflect the area contact feature of force feedback datagloves.…”

Virtual hands play key roles in three-dimensional interaction in various virtual reality applications. However, their visual realism has seldom been seriously discussed in the community of human computer interaction, not to mention the challenging balance between their visual/motion realism and real-time performance. In this paper, a novel approach for virtual hand interaction modeling based on dual quaternion is proposed. Specifically, dual quaternion blending (DQB) is introduced as pseudo muscular layer of our virtual hand model instead of traditional linear blending (LB) and quaternion blending (QB) due to its advantages in muscular deformation. A framework for virtual hand interaction is proposed which supports both gesture interactions and 3D manipulations. Experimental results show that our proposed virtual hand interaction model is suitable for most virtual reality applications and achieves good visual/motion realism while maintains real-time performance.
