LiftTiles

Abstract

Figure 1: A modular inflatable actuator as a building block for prototyping room-scale shape-changing interfaces. Each actuator can extend from 15 cm to 150 cm (A-C). By constructing these modular blocks, a designer can easily prototype different room-scale shape-changing interfaces, such as a 5 x 5 array of room-scale shape display that a user can sit down and step on (D-E).

Interacting with actuated walls: Exploring applications and input types

“…While investigations of small-scale shape displays have been thoroughfrom handheld (Jang et al, 2016;Alexander et al, 2012) to tabletop (Leithinger and Ishii, 2010;Follmer et al, 2013;Leithinger et al, 2011;Siu et al, 2018;Taher et al, 2015;Hardy et al, 2015) -comparatively, little research explores large-scale shape displays, even though different scales have proven to be able to impact user experience (López García and Hornecker, 2021). Work like TilePoP (Teng et al, 2019), LiftTiles (Suzuki et al, 2020), KINEIN Economidou et al (2021b), and Elevate (Je et al, 2021) is beginning to explore this new design space for large-scale shape displays. In these projects, researchers created floors made of pin-array cubes moving up and down.…”

“…Our findings are different from previous work and inspirational for the following reasons: first, we extended the knowledge of the potential use cases with wall shape-changing interfaces beyond the aesthetic purpose, (e.g., Rogers and Design Studio, 2010;Yang, 2012;Goulthorpe et al, 2012;Khan, 2014). Though researchers developed various types of systems to demonstrate the great potential of using shape-changing systems to meet all kinds of purposes (Suzuki et al, 2020;Gross and Green, 2012;Je et al, 2021), we summarized and emphasized possible applications for researchers and designers to explore in the future. Such knowledge is essential as designing applications and content has been argued to be one of the major challenges of shape-changing interface research (Alexander et al, 2018).…”

Human-Scale Personal Fabrication

“…At the intersection of fabrication and virtual reality lies TurkDeck [17], a system that physically builds virtual environments around a virtual reality user on-the-fly. Finally, room-scale objects have been also instantiated by a large shape display by Suzuki et al [91].…”

CoVR: A Large-Scale Force-Feedback Robotic Interface for Non-Deterministic Scenarios in VR

“…Only few prototypes provide a high amount of force feedback. TilePop [62] or LiftTiles [59] modify the floor topology with a large inflatable mat covering the surface of the VR arena. This provides high vertical force feedback and hence supports whole-body interactions below 1m (eg user sitting [74]), despite slow inflation (5s) and deflation (20s) times.…”
