我们提出了TiltChair，一种驱动的办公椅，通过主动倾斜椅子的座位来物理地操纵用户的姿势，以解决与长时间坐着相关的问题。该系统控制倾斜角度和运动速度，以实现可操纵但不突兀的姿态引导。为了展示其潜力，我们首先建造了一个TiltChair的原型，它的座椅可以通过气动控制倾斜。然后，我们通过两个实验研究了座椅的倾斜角度和运动对任务绩效和整体坐姿体验的影响。结果表明，倾斜角度主要影响姿势维持的难易程度，而动作速度则影响动作的显著性和主观可接受性。然而，这些座位条件并不影响客观的任务表现。基于这些结果，我们提出了一个设计空间，以促进有效的座椅倾斜行为使用的角度，速度和连续性的三个维度。此外，我们讨论了有前途的应用。
We propose TiltChair, an actuated office chair that physically manipulates the user’s posture by actively inclining the chair’s seat to address problems associated with prolonged sitting. The system controls the inclination angle and motion speed with the aim of achieving manipulative but unobtrusive posture guidance. To demonstrate its potential, we first built a prototype of TiltChair with a seat that could be tilted by pneumatic control. We then investigated the effects of the seat’s inclination angle and motions on task performance and overall sitting experience through two experiments. The results show that the inclination angle mainly affects the difficulty of maintaining one’s posture, while the motion speed affected the conspicuousness and subjective acceptability of the motion. However, these seating conditions did not affect objective task performance. Based on these results, we propose a design space for facilitating effective seat-inclination behavior using the three dimensions of angle, speed, and continuity. Furthermore, we discuss promising applications.
