We propose and develop MarbLED, which can change existing kitchen worktops or counters with engineered marble into a surface computing platform. The hardware was assembled with through-hole packages previously. We have designed and assembled surface-...

While end users can acquire full 3D gestures with many input devices, they often capture only 3D trajectories, which are 3D uni-path, uni-stroke single-point gestures performed in thin air. Such trajectories with their $(x,y,z)$ coordinates could be ...

Since its introduction in 2005, the TUIO protocol has been widely employed within a multitude of usage contexts in tangible and multi-touch interaction. While its simple and versatile design still covers the core functionality of interactive tabletop ...

Reminiscence Therapy can act as an effective and conducive method for increasing the Quality of Life (QoL) of people with dementia (PwD) when implemented properly. In addition to non-digital approaches, digitally enhanced systems can be built to elicit ...

Surface computing allows flexible search interaction where users can manipulate the representation of entities recommended for them to create new queries or augment existing queries by taking advantage of increased screen estate and almost physical ...

While most mobile platforms offer motion sensing as input for creating tactile feedback, it is still hard to design such feedback patterns while the screen becomes larger, e.g. tabletop surfaces. This demonstration presents Ubitile, a finger-worn ...

Inspired by the promise of tabletops for collaborative learning, and building on the many tabletop lab studies, and a few in-the-wild tabletop classrooms, we designed the first semester-long use of a multi-tabletop classroom for two university subjects, ...

This paper presents ACH Walkthrough, a prototype software client server application to demonstrate the potential benefits of surface technologies in collaborative security intelligence analysis. The basis is the ACH (Analysis of Competing Hypotheses) ...

The average person can skillfully manipulate a plethora of tools, from hammers to tweezers. However, despite this remarkable dexterity, gestures on today's touch devices are simplistic, relying primarily on the chording of fingers: one-finger pan, two-...

Instant access to computing, when and where we need it, has long been one of the aims of research areas such as ubiquitous computing. In this paper, we describe the WorldKit system, which makes use of a paired depth camera and projector to make ordinary ...

Many new technologies are emerging that make it possible to extend interaction into the three-dimensional space directly above or in front of a multitouch surface. Such techniques allow people to control these devices by performing hand gestures in the ...

Interactive surfaces have great potential for co-located collaboration because of their ability to track multiple inputs simultaneously. However, the multi-user experience on these devices could be enriched significantly if touch points could be ...

Multitouch-Multiuser Table Computing is the new paradigm for accessing rich information in public spaces. As revolutionary natural user interfaces provide new ways of interacting with virtual information spaces, visual information developers must ...

Natural forms of interaction have evolved for personal devices that we carry with us (mobiles) as well as for shared interactive displays around us (surfaces) but interaction across the two remains cumbersome in practice. We propose a novel cross-device ...

People often use mobile devices to access information during conversations in casual settings, but mobile devices are not well suited for interaction in groups. Large situated displays promise to better support access to and sharing of information in ...

Multi-touch tables are becoming increasingly popular and much research is dedicated to developing suitable interaction paradigms. There also exist multiple techniques aimed at extending interactions into the hoverspace---the space directly above a multi-...

The tabletop computer interface has the potential to support idea generation by a group using the brainstorming technique. This paper describes the design and implementation of a table-top brainstorming system. To gain insights into its effectiveness, ...

Mobile Multitouch is a system that consists of a modern smartphone and a large stationary multi-touch table. The user can record audio, video or pictures with the smartphone. GPS location of the recording is saved along with the media files. User can ...

New forms of natural user interfaces, particularly tabletops, are now a possibility due to the staggering advances in sensing and display technology. There is an immediate need for corresponding progress on the foundational software for exploiting the ...

The usability of surface computing applications largely depends on a thorough consideration of the specific characteristics and constraints of surface computers during development. Nevertheless, established user interface design processes do not ...
