In the good old days, the human was here, the computer there, and a good living was to be made by designing ways to interface between the two. Now we find ourselves unthinkingly pinching to zoom in on a picture in a paper magazine. User interfaces are ...

We present the development of the interactive system integrating multi-touch tabletop and projection-based Augmented Reality (AR). The integrated system supports the flexible presentation of multiple UI components, which is suitable for multi-touch ...

Large format displays are commonplace for viewing large scientific datasets. These displays often find their way into collaborative spaces, allowing for multiple individuals to be collocated with the display, though multi-modal interaction with the ...

We present a novel approach to integrating a touch screen device into the experience of a user wearing a Head Mounted Display (HMD) in an immersive virtual reality (VR) environment with tracked head and hands.

Depth-based gesture cameras provide a promising and novel way to interface with computers. Nevertheless, this type of interaction remains challenging due to the complexity of finger interactions and the under large viewpoint variations. Existing ...

We present HoloLeap, which uses a Leap Motion controller for 3D model manipulation on a light field display (LFD). Like autostereo displays, LFDs support glasses-free 3D viewing. Unlike autostereo displays, LFDs automatically accommodate multiple ...

We present a user study that takes an in-depth look at the effect of immersion cues on 3D spatial problem solving by combining traditional performance and experience measures with brain data.

We investigated mouse-based 3D selection using one-eyed cursors, evaluating stereo and head-tracking. Stereo cursors significantly reduced performance for targets at different depths, but the one-eyed cursor yielded some discomfort.

Walking is usually considered the most natural form for self-motion in a virtual environment (VE). However, the confined physical workspace of typical virtual reality (VR) labs often prevents natural exploration of larger VEs. Redirected walking has ...

Contactless motion sensing devices enable a new form of input that does not encumber the user with wearable tracking equipment. We present a novel travel technique using the Leap Motion finger tracker which adopts a 2DOF steering metaphor used in ...

In this work, we present an initial user study that explores the use of a dedicated inertial measurement unit (IMU) to achieve spatial awareness in Multi-surface Environments (MSE's). Our initial results suggest that measurements provided by an IMU may ...

In this research, we propose a linear SVM classification model for perceptual distal target selection on large displays. The model is based on two simple features of users' finger movements reflecting users' visual perception of targets. The model shows ...

Medical imaging is essential to support most diagnosis. It often requires visualizing individual 2D slices from 3D volumetric datasets and switching between both representations. Combining an overview with a detailed view of the data [1] enables to keep ...

We propose a novel spatial-temporal feature set for sign language recognition, wherein we construct explicit spatial and temporal features that capture both hand movement and hand shape. Experimental results show that the proposed solution outperforms ...

In this poster, we present an experiment to capture user's natural pointing posture in distal pointing tasks at large displays and to examine the effect of pointing posture on the performance of distal pointing tasks. There were two types of pointing ...

In this poster we present the design and evaluation of a Handheld Augmented Reality (HAR) prototype system for guidance.

3D printing has shown great potential in creating tactile picture books for blind children to develop emergent literacy. Sighted children can be motivated to contribute to the modeling of more tactile picture books. But current 3D design tools are too ...

Physical visualizations are an emergent area of research and appear in increasingly diverse forms. While they provide an engaging way of data exploration, they are often limited by a fixed representation and lack interactivity. In this work we discuss ...

We propose a gesture-based 3D modeling system, which allows the user to create and sculpt a 3D model with hand-gestures. The goal of our system is to provide a more intuitive 3D user interface than the traditional 2D ones such as mouse or touch pad. ...

We build upon recent research designing a constructive, multi-touch emotional assessment tool and present preliminary qualitative results from a Wizard of Oz study simulating the tool with clay. Our results showed the importance of emotionally ...
