“…Thus, our results for throughput values for mid-air tapping with fog are 32% higher than the 1.75 bps reported previously for pure mid-air tapping [15]. Furthermore, the results are comparable with the values of 2.10-2.25 bps for mid-air gesture selection with large conventional displays, where selection confirmation was executed by voice or button press [18,19] but lower than the values of 4-6 bps for large touchscreen interaction [34,35]. Regarding dwell-based selection with fog, its throughput is also comparable to the values of 1.7-1.9 bps previously reported [15,21].…”

Projected walk-through fogscreens have been created, but there is little research on the evaluation of the interaction performance with fogscreens. The present study investigated mid-air hand gestures for interaction with a large fogscreen. Participants (N = 20) selected objects from a fogscreen using tapping and dwell-based gestural techniques, with and without vibrotactile/haptic feedback. In terms of Fitts’ law, the throughput was about 1.4 bps to 2.6 bps, suggesting that gestural interaction with a large fogscreen is a suitable and effective input method. Our results also suggest that tapping without haptic feedback has good performance and potential for interaction with a fogscreen, and that tactile feedback is not necessary for effective mid-air interaction. These findings have implications for the design of gestural interfaces suitable for interaction with fogscreens.

“…Touch screens have previously been reported to be faster but less accurate than a mouse (Burno et al, 2015; Sambrooks & Wilkinson, 2013, Stevenson et al, 2004). When using vision to guide movement termination on a touch screen, the finger/hand may obscure site of the target (see Van Veldhuizen & Yang, 2021) and this may be a greater problem on smaller screens (List & Kipp, 2019).…”

Incompatibility Influences Cursor Placement When Pointing to Images of Cups

Objective As images are used within graphical user interfaces to signify menu selection, it is important to understand how image properties can influence cursor placement online. Background Objects have multiple dimensions that create potential ambiguity and Stroop-like confusions for the operator if a previously habitual response conflicts with the required response. Methods To examine the impact of compatibility and other contextual factors, 41 participants used a computer Mouse or touch screen to place the cursor upon images of full or empty cups that varied in size, and direction of handle. Results Cursor placements took longer using the Mouse than touch screen. Although participants were placing the cursor on images, the size of the cup, whether it was empty or full, and the handle orientation interacted in their effects upon response duration and cursor placement. The effects of cup size reversed for empty cups or those with incompatible handles. Conclusion Context can influence cursor placement. Perceived spillability influenced precision requirements, and the cup handle can serve as target or a flanking distractor. Application Image content can influence screen hotspots. As performance can change with cup spillability, this bodes well for attempts to detect intent from cursor trajectories.

“…Usually, the small-sized screen was divided into several rectangular areas for performance evaluation. List and Kipp (2019) compared the middle-sized and large-sized touchscreen devices and found that the middle-sized devices allow for greater interaction speed but a high error rate.…”

Previous studies have used the Fitts' Law to predict the performance of pointing task on touch screens. It was found that moving distance, target width, and the direction of motion would affect the task performance. The present research aimed to investigate the impact of the initial and terminal positions (ITPs) on pointing performance in two Exps. ITPs were divided into two categories: center of a screen and outer of a screen (center ↔ outer) pointing, and outer of a screen to outer of a screen (outer→outer) pointing. In Exp 1, 30 participants performed the center ↔ outer pointing tasks with 8 directions. The results showed that the outer → center movement was significantly faster than the center → outer at 45°, 90°, and 180°. In Exp 2, 30 participants performed the outer → outer pointing tasks with eight directions. The current study revealed that the ITPs influenced the performance of the pointing task, possibly due to human biomechanical characteristics associated with different movements.
