Publication: Matthijs Kwak, Kasper Hornbæk, Panos Markopoulos, and Miguel Bruns Alonso. 2014. The design space of shape-changing interfaces: a repertory grid study. In Proceedings of the 2014 conference on Designing interactive systems (DIS '14). ACM, New York, NY, USA, 181-190. DOI: http://dx.doi.org/10.1145/2598510.2598573 Abstract: Technologies for shape-changing user interfaces are rapidly evolving, but our understanding of the design space of such interfaces is still limited. We report a repertory grid study that aims to describe the design space from the users' point of view by eliciting personal constructs about shape-change. The study is based on six similar-sized, shape-changing artifacts that combine simple sensing of users with actuation that change volume, texture, and orientation. Our results show that the 18 respondents distinguish artifacts on dimensions that differ from those of most models of shape change. For instance, they characterize shape-change in terms of personality, territoriality, and state of mind, in addition to more common categories such as appearance and product properties. We discuss how the dimensions derived from users might be used to design shape-changing interfaces.]]>

We conducted two user studies with 14 and 24 participants respectively and report: (1) force profile graphs that depict the force variations of common touch gestures, (2) the effect of the different conditions on force exerted and gesture completion time, (3) the most common forces that users apply, and the time taken to complete the gestures.

DOI: http://dx.doi.org/10.1145/2807442.2807451 Abstract: Digital fabrication machines such as 3D printers and laser-cutters allow users to produce physical objects based on virtual models. The creation process is currently unidirectional: once an object is fabricated it is separated from its originating virtual model. Consequently, users are tied into digital modeling tools, the virtual design must be completed before fabrication, and once fabricated, re-shaping the physical object no longer influences the digital model. To provide a more flexible design process that allows objects to iteratively evolve through both digital and physical input, we introduce bidirectional fabrication. To demonstrate the concept, we built ReForm, a system that integrates digital modeling with shape input, shape output, annotation for machine commands, and visual output. By continually synchronizing the physical object and digital model it supports object versioning to allow physical changes to be undone. Through application examples, we demonstrate the benefits of ReForm to the digital fabrication process. ]]>

Accompanying research article at http://dl.acm.org/citation.cfm?id=2557164 Audio and vibrotactile output are the standard mechanisms mobile devices use to attract their owner's attention. Yet in busy and noisy environments, or when the user is physically active, these channels sometimes fail. Recent work has explored the use of physical shape-change as an additional method for conveying notifications when the device is in-hand or viewable. However, we do not yet understand the effectiveness of physical shape-change as a method for communicating in-pocket notifications. This paper presents three robustly implemented, mobile-device sized shape-changing devices, and two user studies to evaluate their effectiveness at conveying notifications. The studies reveal that (1) different types and configurations of shape-change convey different levels of urgency and; (2) fast pulsing shape-changing notifications are missed less often and recognised more quickly than the standard slower vibration pulse rates of a mobile device.]]>

Recent work has explored the use of physical shape-change as an additional method for conveying notifications when the device is in-hand or viewable. However, we do not yet understand the effectiveness of physical shape-change as a method for communicating in-pocket notifications. This paper presents three robustly implemented, mobile-device sized shape-changing devices, and two user studies to evaluate their effectiveness at conveying notifications. The studies reveal that (1) different types and configurations of shape-change convey different levels of urgency and; (2) fast pulsing shape-changing notifications are missed less often and recognised more quickly than the standard slower vibration pulse rates of a mobile device.]]> Sun, 14 Aug 2016 09:31:57 GMT /slideshow/evaluating-the-effectiveness-of-physical-shapechange-for-inpocket-mobile-device-notifications/64977926 SriramSubramanian2@slideshare.net(SriramSubramanian2) Evaluating the Effectiveness of Physical Shape-Change for In-pocket Mobile Device Notifications SriramSubramanian2 Accompanying research article at http://dl.acm.org/citation.cfm?id=2557164 Audio and vibrotactile output are the standard mechanisms mobile devices use to attract their owner's attention.

LeviPath is a modular system to levitate objects across 3D paths. It consists of two opposed arrays of transducers that create a standing wave capable of suspending objects in mid-air. To control the standing wave, the system employs a novel algorithm based on combining basic patterns of movement. Our approach allows the control of multiple beads simultaneously along different 3D paths. Due to the patterns and the use of only two opposed arrays, the system is modular and can scale its interaction space by joining several LeviPaths. In this paper, we describe the hardware architecture, the basic patterns of movement and how to combine them to produce 3D path visualisations.]]>
