“…A more representative ongoing task, and one that imposed costs if not performed well, would limit the frequency with which participants are able to check on patients away from the task at hand, increasing the usefulness of the information on HWD. Previous literature suggests that in constrained contexts like this, participants using HWDs can maintain focus on their current task but still use the HWD to acquire information (Liu, Jenkins, Sanderson, et al, 2009; Pascale et al, 2018; Winterbottom et al, 2015; Woodham et al, 2016); however, more exploration is needed in multiple patient monitoring contexts.…”

“…HWDs, however, are sometimes associated with visual, perceptual, and performance costs. For example, stimuli presented on an HWD can go undetected (Liu, Jenkins, Sanderson, et al, 2009; Pascale et al, 2018), have an impact on ongoing tasks (He, Choi, McCarley, Chaparro, & Wang, 2015; He, Ellis, Choi, & Wang, 2015; He et al, 2018; Sawyer, Finomore, Calvo, & Hancock, 2014; Woodham, Billinghurst, & Helton, 2016), and reduce the user’s ability to walk normally (Mustonen, Berg, Kaistinen, Kawai, & Hakkinen, 2013).…”

To investigate whether head-worn displays (HWDs) help mobile participants make better alarm management decisions and achieve better situation awareness than alarms alone. Background: Patient alarms occur frequently in hospitals but often do not require clinical intervention. Clinicians may become desensitized to alarms and fail to respond to clinically relevant alarms. HWDs could make patient information continuously accessible, support situation awareness, and help clinicians prioritize alarms. Method: Experiment 1 (n = 76) tested whether nonclinicians monitoring simulated patients benefited from vital sign information continuously displayed on an HWD while they performed a secondary calculation task. Experiment 2 (n = 13) tested, across three separate experimental sessions, how effectively nursing trainees monitored simulated patients' vital signs under three different display conditions while they assessed a simulated patient. Results: In Experiment 1, participants who had access to continuous patient information on an HWD responded to clinically important alarms 25.9% faster and were 6.7 times less likely to miss alarms compared to participants who only heard alarms. In Experiment 2, participants using an HWD answered situation awareness questions 18.9% more accurately overall than when they used alarms only. However, the effect was significant in only two of the three experimental sessions. Conclusion: HWDs may help users maintain continuous awareness of multiple remote processes without affecting their performance on ongoing tasks. Application: The outcomes may apply to contexts where access to continuous streams of information from remote locations is useful, such as patient monitoring or clinical supervision.

“…According to the imaging principle of the camera, the transformation relationship between the identification coordinate system and the screen coordinate system is shown in equation (1) xy in the observation coordinate system. The optical imaging of the camera is not completely equivalent to the ideal hole imaging, and there will inevitably be distortion, which is mainly divided into radial distortion and tangential distortion [27,28]. Among these two kinds of distortion, radial distortion is the most important distortion factor, and its mathematical model can be expressed as: x y z in the camera coordinate system, and that the point transferred to the imaging plane is ideally point ( , ) u u u P x y .…”

The traditional navigation system used in spinal puncture is not able to monitor the surgical process in real time and the accuracy of navigation is unsatisfactory. In this study, an augmented reality surgical navigation system based on multi-view virtual and real registration is proposed to solve these problems. The theory of virtual and real registration in augmented reality technology is analyzed, and the methods of single-view and multi-view virtual and real registration are compared. The principle of coordinate transformation in the surgical navigation module is analyzed. The platform of augmented reality surgical navigation system based on multi-view virtual and real registration technology is designed. The experiments of the spinal model are used to verify the accuracy of virtual and real registration. The accuracy of the proposed navigation system is verified by the experiment of simulating puncture operation with robotic control of surgical tool. The experimental results show that the accuracy of single-view and multi-view virtual and real registration is 9.85 0.80  mm and 1.62 0.22  mm respectively. The accuracy of the augmented reality surgical navigation system added with multi-view virtual and real registration technology is 1.70 0.25  mm, which is 35% higher than that of the augmented reality surgical navigation system not previously used. The augmented reality surgical navigation system for spinal puncture based on multi-view virtual and real registration proposed in this study can meet the requirements of physician on the accuracy of surgery. It can also help physician to monitor the surgical process in real time and improve the success rate of surgery.

Head-worn displays (HWDs) as timely condition monitoring are increasingly used in aviation. However, interface design characteristics that mainly affect HWD use have not been fully investigated. The aim of this study was to examine the effects of several important interface design characteristics (i.e., the distance between calibration lines and the layouts of vertical and horizontal scale belts) on task performance and user preference between different conditions of display, i.e., HWD or head-up display (HUD). Thirty participants joined an experiment in which they performed flight tasks. In the experiment, the calibration lines’ distance was set to three different levels (7, 9 and 11 mrad), and the scale belt layouts included horizontal and vertical scale belt layouts. The scale belts were set as follows: the original vertical scale belt width was set as L, and the horizontal scale belt height as H. The three layouts of the vertical calibration scale belt used were 3/4H, H and 3H/2. Three layouts of horizontal calibration scale belts were selected as 3L/4, L and 3L/2. The results indicated that participants did better with the HWD compared to the HUD. Both layouts of vertical and horizontal scale belts yielded significant effects on the users’ task performance and preference. Users showed the best task performance while the vertical calibration scale belts were set as H and horizontal calibration scale belts were set as L, and users generally preferred interface design characteristics that could yield an optimal performance. These findings could facilitate the optimal design of usable head-worn-display technology.
