“…Within the last 15 years, studies on soft robotics and mechanisms have gained momentum. 30–42 They mainly involve many fields related to, for example, wearable devices, medical equipment, and item grabbing. Soft robotics have better potential for flexibility and human–robot interaction safety, and pneumatic actuation is one of the essential driving principles.…”

Usually, traditional insulation materials have a constant thermal resistance value that cannot change within the ambient temperature and will decrease as ambient humidity or external stress increases. Humans heavily rely on heating, ventilation, and air conditioning (HVAC) systems to meet the thermal comfort requirements of their bodies, giving rise to energy waste and global warming. As an infinitely available natural resource, air is one of the most efficient thermal retaining substances known to science. Inspired by soft pneumatic robotics, we propose an architecture for air-driven thermoregulation fabrics called soft robotic fabrics (SRF). By changing the thickness of trapped air layer in fabric system through SRF, wearers could modify garments’ thermal insulation performance. A fabrication method is introduced to rapidly manufacture low-cost pneumatic structures using various types of construction and dimensions. With excellent ductility, elasticity, and compression resistance, the thickness of SRF increases by 12 times or more after inflation, and the fabric even can lift an object 270 times heavier than its weight. The excellent deformability can effectively increase stable air layer between clothing and skin. Based on the Predicted Mean Vote–Predicted Percentage of Dissatisfied model, the thermoregulation capability of SRF helps HVAC expand the temperature setpoint range by 3–8 times when compared with traditional fabrics, and has far-reaching significance in saving energy.

“…A shape-changing interface is capable of physically transforming or changing its form, thereby enabling novel forms of interaction between humans and machines. Yao et al [42] proposed a programmable shape-changing interface and explored its design space, including a height-changing tangible icon for a mobile app or a transformable tablet case. Cui et al [7] presented a construction kit for a shape-changing interface and proposed designing robot behavior as its application.…”

“…Prior work enabled devices capable of changing their softness, e.g., through jamming [20,80]. Adding a jamming layer on top of an existing shape-changing device such as LayerPump [28], dynamically changeable buttons [32,40], the infatable hemispherical display [83], PneUI [97], AirPinch [33], MultiJam [96], Pneumatic Auxetics [16], StringTouch [73], or PneuSeries [8], allows building devices providing haptic feedback through both softness and shape. The jamming layer can follow the shape of the shape-changing device, thanks to its malleability prior to jamming [80,97].…”

“…Curved and soft materials gained increasing attention in the past decades in HCI [72]. The perception of the curvature of a soft surface comes into play, e.g., in virtual reality (VR) when a user is touching a surrounding daily object (e.g., a ball) to get haptic feedback [41], when a surgeon trains in VR with a soft organ proxy providing feedback through local curvature [61], when getting curvature-based shape notifcations from a soft mobile device [97], or when soft physical buttons switch between diferent modes based on their curvature [40]. In these cases, the user experience is afected by the perceived curvature of the soft surface [1,54].…”

Soft (compliant) curvature-changing UIs provide haptic feedback through changes in softness and curvature. Diferent softness can impact the deformation of UIs when worn and touched, and thus impact the users' perception of the curvature. To investigate how softness impacts users' perception of curvature, we measured participants' curvature perception accuracy and precision in diferent softness conditions. We found that participants perceived the curviest surfaces with similar precision in all diferent softness conditions. Participants lost half the precision of the rigid material when touching the fattest surfaces with the softest material. Participants perceived all curvatures with similar accuracy in all softness conditions. The results of our experiment lay the foundation for soft curvature perception and provide guidelines for the future design of curvature-and softness-changing UIs.
