“…First, the user selects a bone, which will become the chain's end-effector. 13 Then, the user moves the right controller close to another bone and presses the Trackpad Down-Left/Right button to set it as a pole (that controls the direction of the chain) or as a target (that controls the position of the end-effector), respectively. With the Trackpad Up-Left/Right buttons, the user can increase/decrease the IK chain's length, supposed that the selected bone has an IK constraint associated; otherwise, the length value set will be assigned to the next selected bone with that constraint.…”

“…Unfortunately, this approach would break the sense of presence and could present serious interaction issues due to the use of 2D interface elements in a 3D environment, to the limited resolution of the VR display, etc. [13]. Moreover, although the adoption of a familiar interface could simplify operations for users with previous experience with Blender, a direct replication of complex tools available in the considered animation suite that are notoriously hard to use for novice users would automatically translate their complexity to VR.…”

Immersive Virtual Reality-Based Interfaces for Character Animation

Virtual Reality (VR) has increasingly attracted the attention of the computer animation community in search of more intuitive and effective alternatives to the current sophisticated user interfaces. Previous works in the literature already demonstrated the higher affordances offered by VR interaction, as well as the enhanced spatial understanding that arises thanks to the strong sense of immersion guaranteed by virtual environments. These factors have the potential to improve the animators' job, which is tremendously skillintensive and time-consuming. The present paper explores the opportunities provided by VR-based interfaces for the generation of 3D animations via armature deformation. To the best of the authors' knowledge, for the first time a tool is presented which allows users to manage a complete pipeline supporting the above animation method, by letting them execute key tasks such as rigging, skinning and posing within a wellknown animation suite using a customizable interface. Moreover, it is the first work to validate, in both objective and subjective terms, character animation performance in the above tasks and under realistic work conditions involving different user categories. In our experiments, task completion time was reduced by 26%, on average, while maintaining almost the same levels of accuracy and precision for both novice and experienced users.
