ReflectU: A Mirror-Based Intelligent Interactive System for Intuitive Remote Control

Large interactive displays (LID) are widely used in industrial scenarios to enhance ubiquitous and seamless human-machine interactions. However, few studies have pay attention to design implicit interaction that users can directly manipulate physical circumstance without touch or specific gesture. This paper proposes \emph{ReflectU}, a novel reflection-based approach that leverages mirror reflection for a natural and implicit interactive method for remote control, i.e., user will be able to directly interact with physical circumstance just via the reflection of their bare hands. We compare its performance with that of other two generally known devices: Wii Remoter and Microsoft Kinect. Moreover, performance metrics of ReflectU are evaluated in real-life scenario and provide evidence in convincing performance in both tasks requiring instant targeting and trajectory control. Furthermore, ReflectU is reported by users to be the most intuitive and satisfactory approach among all three candidates in user studies.

The Role of the Self-Presence for Interactive Large Digital Displays: Gesture Interactivity and Mirrored-Self Image for Advertising Content

ABSTRACT The gesture interactivity and self-mirroring effects of large digital displays, also known as digital signage, was investigated using the self-presence theory and engagement. By extending the interactive effects of gesture and self-mirroring from the immersive environment to a large interactive display (LID), this study found the implicit mediating roles of social presence and engagement for advertising effectiveness through a 2 (gesture; non-gesture vs. gesture interactivity) x 2 (self-representation; non-self-mirroring vs. self-mirroring interactivity) between-subject design (N = 81) experiment. The results indicated that gesture interactivity enhances a feeling of self-presence, not self-mirroring, and it positively fosters psychological engagement with advertising content. In turn, the heightened engagement results in better advertising effectiveness, such as brand attitude, purchase intention, and recall.

On the Use of Large Interactive Displays to Support Collaborative Engagement and Visual Exploratory Tasks.

Large interactive displays can provide suitable workspaces for learners to conduct collaborative learning tasks with visual information in co-located settings. In this research, we explored the use of these displays to support collaborative engagement and exploratory tasks with visual representations. Our investigation looked at the effect of four factors (number of virtual workspaces within the display, number of displays, position arrangement of the collaborators, and collaborative modes of interaction) on learners’ knowledge acquisition, engagement level, and task performance. To this end, a user study was conducted with 72 participants divided into 6 groups using an interactive tool developed to support the collaborative exploration of 3D visual structures. The results of this study showed that learners with one shared workspace and one single display can achieve better user performance and engagement levels. In addition, the back-to-back position with learners sharing their view and control of the workspaces was the most favorable. It also led to improved learning outcomes and engagement levels during the collaboration process.

P‐14: Student Poster: Optical Sensor with New Driving Method Using Amorphous Silicon Thin‐Film Transistors to Increase Three Types of Sensed Light for Large Interactive Displays

This paper presents optical sensors with a new driving method based on hydrogenated amorphous silicon thin‐film transistors (a‐Si:H TFTs) covered with the color filters to increase three types of sensed light. The measurement results indicate that the differences of output voltage are all above 16.5 V, proving that the proposed sensors are suitable for integrating large interactive display.

Collaboration on large interactive displays: a systematic review

Large Interactive Displays (LIDs), such as tabletops or interactive walls, are promising innovations, which are increasingly used to support co-located collaboration. Yet the current evidence base on the impact of LID use on collaborative processes and outcomes, and associated influencing factors, is fragmented, particularly in comparison with other media. To address this gap, a systematic review was carried out in the databases Web of Science, Psych.Info, ACM, Elsevier, JSTOR and Springer and in the ACM CHI conference database. A corpus of 38 articles with experimental study designs met the eligibility criteria and was analyzed in-depth. With regard to collaboration processes, the findings suggest a relatively clear advantage of the use of LIDs over classic forms of collaboration, in particular over single-user environments (e.g. laptops). With attention to collaborative outcomes, positive effects of LIDs were identified for knowledge gains and social encounters, and mixed effects for task-related outcomes. The analysis further shows relevant influencing factors of LID, such as the separation of personal and joint work spaces and the deployment of horizontal instead of vertical displays. Conceptual and practice implications are discussed.

ThunderPunch: A bare-hand, gesture-based, large interactive display interface with upper-body-part detection in a top view.

We present a new bare-hand gesture interface for large-screen interaction in which multiple users can participate simultaneously and interact with virtual content directly. To better reflect the intent of our new interface, we have created a new type of hardware system with a large hybrid display, named ThunderPunch. Unlike the conventional method, which involves positioning the camera in front, the cameras are mounted on the ceiling so that they avoid covering the large screen. To achieve bare-hand interaction in this hardware structure, we propose real-time algorithms that detect multiple body poses and recognize punching and touching gestures from top-view depth images. A pointing and touching test shows that the proposed algorithm is usable and that it outperforms other algorithms. In addition, we created a game to make the best use of the proposed system.

Nano-crystalline oxide semiconductor devices offer an attractive alternative to the traditional display technology, enabling to realize high resolution, high motion speed and large area interactive display products with remote touch functionality and transparent electronics. Also it provides the novel device approaches over traditional down-scaling methods employed in ultra large scale integration. Here, we present various semiconductor and display device applications by using nano-crystalline oxide semiconductor materials.
