Sitting Posture Recognition Using a Spiking Neural Network

Human Factors Evaluation of an Ambient Display for Real-Time Posture Feedback to Sedentary Workers

“…Based on the past studies on taxonomy of ambient display [53]- [56] and the previously developed on-screen displays for posture feedback system [11], [12], [14], [18]- [20], [22], [24], [27], [33], the current study considered the following distinguishing design characteristics between ambient display and on-screen display in developing the two posture feedback displays:…”

“…The intervention based on self-monitoring, however, is limited in that the workers need to continuously maintain attention to their own postures while performing the primary work taskdivided attention generally lowers one's ability to inhibit a habitual behavior [10]. In an attempt to address the limitation of selfmonitoring, several studies have developed real-time posture feedback systems [11]- [33]. These systems monitored a seated worker's posture continuously over time and provided warnings to the worker when poor postural behaviors occurred.…”

“…These systems monitored a seated worker's posture continuously over time and provided warnings to the worker when poor postural behaviors occurred. The systems have been implemented as wearable devices [12], [14], [25], [29], camera-based systems [18], [20]- [22], [24], and sensor-embedded chairs [15], [16], [19], [28], [30]- [33] or cushions/textiles [26], [27].…”

“…The first objective was to comparatively evaluate an ambient display against two typical conditions (an on-screen display and a no display condition requiring self-monitoring without feedback) in terms of the dual task performance. An on-screen display was adopted as a typical display design alternative because it pertains to one of the most widely used and studied approaches for providing a real-time posture feedback [11], [12], [14], [18] - [20], [22], [24], [27], [33]. The second objective of the current study was to compare the ambient and on-screen displays in terms of perceived detection efficiency and user acceptance.…”

“…The ambient display was designed by the authors through the applications of the human factors display design principles [40], [41]. The on-screen display employed in this study was similar to those of the previous studies [11], [12], [14], [18] - [20], [22], [24], [27], [33]. Some distinguishing design characteristics between the two displays are specifically stated in the section II.…”
