Task performance is a significant focus within the domain of Human-Computer Interaction (HCI), particularly with the advent of technologies like Virtual Reality (VR). Understanding how individuals leverage VR for productive task execution is crucial as researchers continually seek ways to optimize human performance in digital spaces. Various studies have delved into factors influencing human performance in VR settings, including the engagement of primary senses - visual, auditory, and tactile (haptic). However, a notable gap exists in understanding how the intensity and availability of haptic feedback via VR controllers impact users cognitively during task performance. This research project aims to identify the optimal degree of haptic feedback that enhances productivity without causing discomfort. Addressing the research gap surrounding the utilization of varied haptic feedback intensities and availability via VR controllers is pivotal to creating more immersive user experiences. This improvement has the potential to offer more engaging experiences to VR users, particularly those engaged in cognitive-based applications. The primary challenge lies in determining the most effective combination of haptic feedback to enhance user productivity and effectiveness. By tackling this challenge, users can achieve greater success in VR-based tasks, especially in less-than-ideal environments outside the lab. The findings from this research illustrated that participants demonstrated higher performance and reduced frustration when exposed to moderate and consistent haptic feedback. The study suggested that while haptics can be beneficial, their usage should be moderated to avoid overwhelming or discomforting users.
