Research on visual menus, specifically panel and pie menus, has gained widespread attention in recent times. However, limited research focuses on the mid-air interaction when comparing these two menu types. This study aimed to conduct a comprehensive comparison between panel and pie menus in the context of cursor-based mid-air interaction within a photo booth setting. The evaluation involved analyzing muscle activities, performance metrics, and user experience to quantify the differences between the two menus across three menu operations. Our results indicated that the pie menu offered notable advantages by reducing muscular loads, achieving shorter task completion times, and delivering an overall more enjoyable user experience, making it a preferable choice for mid-air interaction in photo booth settings. Conversely, the panel menu exhibited superior scores of learnability and demonstrated enhanced accuracy in the switching operation, suggesting that it might be a better choice for complex and precision-demanding tasks.

The goal of vehicular automation is to enhance driver comfort by reducing the necessity for active engagement in driving. This allows for the performance of non-driving-related tasks (NDRTs), with attention shifted away from the driving process. Despite this, there exists a discrepancy between current in-vehicle display configurations and the escalating demands of NDRTs. This study investigates drivers' preferences for in-vehicle display configurations within highly automated driving contexts. Utilizing virtual reality head-mounted displays (VR-HMDs) to simulate autonomous driving scenarios, this research employs Unity 3D Shape for developing sophisticated head movement tracking software. This setup facilitates the creation of virtual driving environments and the gathering of data on visual attention distribution. Employing an orthogonal experiment, this experiment methodically analyses and categorizes the primary components of in-vehicle display configurations to determine their correlation with visual immersion metrics. Additionally, this study incorporates subjective questionnaires to ascertain the most immersive display configurations and to identify key factors impacting user experience. Statistical analysis reveals that a combination of Portrait displays with Windshield Head-Up Displays (W-HUDs) is favored under highly automated driving conditions, providing increased immersion during NDRTs. This finding underscores the importance of tailoring in-vehicle display configurations to individual needs to avoid distractions and enhance user engagement. [ABSTRACT FROM AUTHOR]

The number and layout of options within pie menus are crucial for determining the direction of radial swiping in mid-air interactions, influencing the physical demands imposed on users. This research examined six distinct option quantities, referred to as menu breadth, and investigated two layouts, designated as menu orientations. These orientations encompass landscape and portrait formats, with the former positioning a top option centred parallel to the horizontal axis, while the latter situates two top options on either side of the vertical axis. The study employed comprehensive metrics, including muscle activity, wrist movement, user performance, and subjective assessments. Our results indicated that the breadth should be controlled to no more than six to ensure high efficiency and align with users’ interactive experience, while breadth 2 should be avoided to eliminate the potential risk of wrist musculoskeletal disorders. Besides, the portrait orientation for breadth 3 and the landscape orientation for breadth 6 were recommended for their lower physiological loads and higher efficiency. Also, the landscape orientation for breadth 4 should be favoured as it outperformed portrait orientation in both wrist movement dimensions. These findings could provide scientific design principles for using pie menus in mid-air interaction within future HCI applications. [ABSTRACT FROM AUTHOR]

Assessments and treatments focused on pelvic asymmetry are common amongst health professionals. However, there is no clear evidence for the reliability of palpatory examinations for pelvic landmarks. This review aimed to investigate the reliability of palpatory examinations for pelvic landmarks. A systematic search was undertaken using eight databases from inceptions to 2021 January 8th, to identify relevant primary studies. Methodological quality of included studies was evaluated using quality appraisal tool for studies of diagnostic reliability (QAREL). Data on kappa statistics were synthesized quantitatively. 10 papers were included. Six papers had moderate methodological quality (50–70% in QAREL). Four pelvic landmarks, including anterior superior iliac spine, posterior superior iliac spine, sacral sulcus or inferior lateral angle were examined. For both inter-rater and intra-rater reliability, kappa statistics were consistently lower than 0.60 regardless of examiners' qualifications or experience levels, or standardisation trainings. As a result of meta-analyses, pooled kappa statics were consistently lower than 0.06 for all landmarks. Consistent evidence was found to suggest that palpatory examinations of pelvic landmarks to detect pelvic asymmetry do not have an acceptable reliability. Therefore, the current evidence does not support the use of these tests in clinical or educational settings. [ABSTRACT FROM AUTHOR]
