“…Thus full conclusions cannot be drawn with our static scenario and further investigation is required to confirm. Our findings show that haptic feedback leads to better performance which is supported by some studies [37], but contradicts others [45]. The latter study found no significant effect of haptic feedback in a virtual throwing task.…”

Research in multimodal interfaces aims to provide immersive solutions and to increase overall human performance. A promising direction is to combine auditory, visual and haptic interaction between the user and the simulated environment. However, no extensive comparison exists to show how combining audiovisuohaptic interfaces would affect human perception and by extent reflected on task performance. Our paper explores this idea and presents a thorough, full-factorial comparison of how all combinations of audio, visual and haptic interfaces affect performance during manipulation. We evaluated how each combination affects the performance in a study (N = 25) consisting of manipulation tasks with various difficulties. The overall performance was assessed using both subjective measures, by assessing cognitive workload and system usability, and objective measurements, by incorporating time and spatial accuracy-based metrics. The results showed that regardless of task complexity, the combination of stereoscopic-vision with the virtual reality headset increased performance across all measurements by 40%, compared to monocular-vision from a generic display monitor. Besides, using haptic feedback improved outcomes by 10% and auditory feedback accounted for approximately 5% improvement.

“…There is strong evidence that assessing performance via Fitts' law for 3D pointing tasks appears to suffer primarily due to latency [89], impaired depth perception [6,51], as well as the lack of haptic (tactile) feedback [9,22,50,80]. The latter two appear to have a direct correlation to what seem to be the benefits of multi-modal interfaces in increasing overall perception [8,9,11,28,82,83].…”

With the rapid growth in virtual reality technologies, object interaction is becoming increasingly more immersive, elucidating human perception and leading to promising directions towards evaluating human performance under different settings. This spike in technological growth exponentially increased the need for a human performance metric in 3D space. Fitts' law is perhaps the most widely used human prediction model in HCI history attempting to capture human movement in lower dimensions. Despite the collective effort towards deriving an advanced extension of a 3D human performance model based on Fitts' law, a standardized metric is still missing. Moreover, most of the extensions to date assume or limit their findings to certain settings, effectively disregarding important variables that are fundamental to 3D object interaction. In this review, we investigate and analyze the most prominent extensions of Fitts' law and compare their characteristics pinpointing to potentially important aspects for deriving a higher-dimensional performance model. Lastly, we mention the complexities, frontiers as well as potential challenges that may lay ahead.
