Successfully performing tasks in virtual environments requires effective interactions between the user and the environment. Virtual reality technology is currently providing consumer-level devices that are being worldwide adopted, thus increasing the user install base. However, the technology presents ‘one-size-fits-all’ solutions that do not account the high variability of users who now have access to it. Virtual reality controllers can be difficult to operate and may fail to map real-world interactions. Efforts on improving human factors have led to custom-made user input devices factoring ergonomics for increasing task completion effectiveness. In this paper, we present a preliminary study on usability, engagement and task completion of two interactive modes that factor the upper limb ergonomics against a normal mode for reaching and grasping objects. Preliminary results from nine participants reaching objects on a table suggest that factoring upper limb ergonomics increase usability, engagement and task success rate. |
