11. Exploring Head-based Mode-Switching in Virtual Reality

Abstract

Mode-switching supports multilevel operations using a limited number of input methods. In Virtual Reality (VR) head-mounted displays (HMD), common approaches for mode-switching use buttons, controllers, and users' hands. However, they are inefficient and challenging to do with tasks that require both hands (e.g., when users need to use two hands during drawing operations). Using head gestures for mode-switching can be an efficient and cost-effective way, allowing for a more continuous and smooth transition between modes. In this paper, we explore the use of head gestures for mode-switching especially in scenarios when both users' hands are performing tasks. We present a first user study that evaluated eight head gestures that could be suitable for VR HMD with a dual-hand line-drawing task. Results show that move forward, move backward, roll left, and roll right led to better performance and are preferred by participants. A second study integrating these four gestures in Tilt Brush, an open-source painting VR application, is conducted to further explore the applicability of these gestures and derive insights. Results show that Tilt Brush with head gestures allowed users to change modes with ease and led to improved interaction and user experience. The paper ends with a discussion on some design recommendations for using head-based mode-switching in VR HMD.

34. Linking autonomy support and health at work: The self-determination theory perspective

Abstract

Based on self-determination theory, this paper formulated and confirmed a theoretical model linking autonomy support and employee health at work via several intervening variables. In total, 828 randomly selected professional employees were surveyed from six total companies in China: three from the manufacturing industry and three from the service industry. The questionnaire responses of these employees were collected and checked through structural equation model analyses. The results demonstrated that, as anticipated, autonomy support positively influenced basic psychological needs satisfaction, which, in turn, had a positive influence on the autonomous motivation of employees and negatively impacted controlled motivation. Correspondingly, autonomous motivation had a significantly positive effect and controlled motivation had a significantly negative effect on employee health at work. We also evaluated the impact of trait affect, i.e., the positive affect and negative affect experienced by employees at work, on the linkage between autonomy support and basic psychological needs satisfaction. Positive affect strengthened this relationship, while negative affected weakened it. This paper enables the progression of future theoretical research on understanding how autonomy support can influence employee health, which will add knowledge to the occupational health psychology literature. To conclude, theoretical contributions and managerial implications are highlighted., Author(s): Yuxin Liu [sup.1] , Jamshed Raza [sup.1] , Jianwei Zhang [sup.2] , Nan Zhu [sup.1] , Habib Gul [sup.1] Author Affiliations: (1) grid.443284.d, 0000 0004 0369 4765, Business School, [...]

Abstract

Abstract Although some adults infected with influenza 2009 A(H1N1)pdm09 viruses mounted high hemagglutination inhibition (HAI) antibody response, they still suffered from severe disease, or even death. Here, we analyzed antibody profiles in patients (n = 31, 17–65 years) admitted to intensive care units (ICUs) with lung failure and invasive mechanical ventilation use due to infection with A(H1N1)pdm09 viruses during 2009–2011. We performed a comprehensive analysis of the quality and quantity of antibody responses using HAI, virus neutralization, biolayer interferometry, enzyme-linked-lectin and enzyme-linked immunosorbent assays. At time of the ICU admission, 45% (14/31) of the patients had HAI antibody titers ≥ 80 in the first serum (S1), most (13/14) exhibited narrowly-focused HAI and/or anti-HA-head binding antibodies targeting single epitopes in or around the receptor binding site. In contrast, 42% (13/31) of the patients with HAI titers ≤ 10 in S1 had non-neutralizing anti-HA-stem antibodies against A(H1N1)pdm09 viruses. Only 19% (6/31) of the patients showed HA-specific IgG1-dominant antibody responses. Three of 5 fatal patients possessed highly focused cross-type HAI antibodies targeting the (K130 + Q223)-epitopes with extremely low avidity. Our findings suggest that narrowly-focused low-quality antibody responses targeting specific HA-epitopes may have contributed to severe infection of the lower respiratory tract.
