| Abstract | Arm fatigue is an important factor affecting user experience in Virtual Reality (VR). In this work, we have proposed ProxyHand and StickHand, virtual hand techniques to address this issue. Using ProxyHand or StickHand, users can flexibly adjust the 3D-spatial offset between the physical hand and its virtual representation. This will allow users to keep their arms in a comfortable posture (vertically down) even when they have to manipulate objects in locations that require lifting of arms using the default interaction method. Proposed ProxyHand and StickHand have a similar Underlying concept that is to introduce a 3D-spatial offset between the physical hand and its virtual representation in VR. However, they respond differently to the user’s hand movements because of different working mechanisms. Question arises whether the 3D-spatial offset will negatively impact the hand control ability as the directness of interaction is being violated. To investigate this, we conducted user studies where users were asked to perform object translation, rotation and hybrid tasks. ProxyHand and StickHand are used in combination in some scenarios to maximize positive impact on the user experience in VR. This raises the question to find the best possible combination of these virtual hands to reduce arm fatigue. Firstly, for this purpose, we combined both virtual hands by manually allowing users to switch between ProxyHand and StickHand. Secondly, we used machine learning to automatically switch between both the virtual hands. Results showed that introduction of a 3D-spatial offset largely reduced the arm fatigue while offering equal performance to the default interaction method for all these tasks; translation, rotation and hybrid task. Users preferred using ProxyHand and StickHand to interact in the VR environment for longer periods of time. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
