“…Given a human body in a speciied pose as input, their method computes a personalized support mesh suited for a speciic pose that may support comfortable seating and can be used to produce a personalized chair for the individual user that uses it. [20] suggested TiltChair, an actuated oice chair that physically manipulates the user's posture by actively inclining the chair's seat. Again, the goal here is to dynamically (unlike Pose to Seat) address problems associated with prolonged static siting.…”

“…he system controls the inclination angle and motion speed with the aim of achieving manipulative but unobtrusive posture guidance. [20,38,50,68], in their ergonomic application idea, suggested a way to make the user sit in a healthier posture, while we allow the user to sit in whatever pose they want while continuously adjusting the environment's arrangement to beter it the user's current pose.…”

With the rapid evolution of technology, computers and their users’ workspaces have become an essential part of our life in general. Today, many people use computers both for work and for personal needs, spending long hours sitting at a desk in front of a computer screen, changing their pose slightly from time to time. This phenomenon impacts people’s health negatively, adversely affecting their musculoskeletal and ocular systems. To mitigate these risks, several different ergonomic solutions have been suggested. This study proposes, demonstrates, and evaluates a technological solution that automatically adjusts the computer screen position and orientation to its user’s current pose, using a simple RGB camera and robotic arm. The automatic adjustment will reduce the physical load on users and better fit their changing poses. The user’s pose is extracted from images continuously acquired by the system’s camera. The most suitable screen position is calculated according to the user’s pose and ergonomic guidelines. Thereafter, the robotic arm adjusts the screen accordingly. The evaluation was done through a user study with 35 users who rated both the idea and the prototype system itself highly.

“…Gradual and therefore seemingly static adaptations generally aim to enhance ergonomic qualities. For instance, a chair that slowly inclined its seat averted prolonged sitting problems [27], a modular table that balanced its height increased seating comfort [108], a smart desk that adapted thermal, visual, air and postural conditions to personal preferences improved health and work productivity [9], and a workstation that adjusted its computer monitor, desk and chair was able to meet ergonomic guidelines [106]. After building trust by iteratively adapting with minimal discomfort, a self-adjustable desk was able to change human posture habits [45], while the gradual adaptations between a tabletop and a wall display allowed a shape-changing table to sustain informal meetings between office workers [29], and a shape-changing public bench triggered strangers to converse with one another by altering its seating angle [30].…”

Responsive architecture envisions the built environment to adapt to the changing needs of its occupants dynamically. Although it is increasingly feasible to move space-defining objects like room dividers by mobile robots, little is known about how or when such spatial adaptations should occur. We therefore measured the experience of 26 occupants while they performed six different activities inside an office breakout room that was being adapted by a robotically moving wall in either a reactive or proactive way. Based on these empirical findings, we propose how autonomous spatial adaptation should primarily aim to balance the spatial, situational and subjective qualities of the resulting sense of place. We also define eight distinct design recommendations that exploit the unique affordances of spatial adaptation. By asserting that future advances in human-building interaction (HBI) should be based on creating appropriate places rather than controlling functional spaces, we foresee how responsive architecture might become as compelling as its static counterpart.
