The wealth of resources online has empowered individuals and businesses with an unprecedented volume of information to aid in decision making processes. However, finding the many details needed for a non-trivial decision can be very labor-intensive. We present AskSheet, a general system that leverages human computation to acquire the inputs to an arbitrary decision spreadsheet provided by the user. The key innovation is the ability to prioritize the inputs by analyzing the user's spreadsheet formulas to calculate value of information for each of the blanks. By directing workers to find the details that impact the end result most, it results in a conclusive decision without gathering all of the inputs. Copyright © 2014 ACM.

The case study presented in this paper aimed at discovering opportunities for ambient intelligence and new interaction methods for a future remote crane-operating environment. The theoretical objective was to carry out an experience-driven research project in an industrial work context, and the practical objective was to create and evaluate a future oriented science fiction prototype. The work was carried out in close co-operation with an industrial partner who was a domain expert in the field of crane industry. The aim was to focus on clearly defined user experience goals to which the industrial partner committed. The consequent immediate objective was to focus on two explicit experiences relating to 'Feeling of being motivated' and to 'Sense of community' that were placed at the core of the design investigations. These experiences were deliberated into a science fiction prototype entitled 'Remote operator's day in a future control centre'. The science fiction prototype was further introduced to users by twofold means: as a plain, simple short story and through an interactive experience path. The main contribution of the paper is to demonstrate how an emerging technology research of a new domain may employ science fiction prototyping method as a primary means of experience design investigations.

IEEE Symposium on 3D User Interfaces (3DUI)

作者： Felipe Bacim Mahdi Nabiyouni Doug A. Bowman Department of Computer Science Center for Human-Computer Interaction

Three-dimensional point clouds are generated by devices such as laser scanners and depth cameras, but their output is a set of unstructured, unlabeled points. Many scenarios require users to identify parts of the point cloud through manual annotation. Inspired by the current generation of “natural user interface” technologies, we present Slice-n-Swipe, a technique for 3D point cloud annotation based on free-hand gesture input. The technique is based on a chef's knife metaphor, and uses progressive refinement to allow the user to specify the points of interest. We demonstrate the Slice-n-Swipe concept with a prototype using the Leap Motion Controller for free-hand gesture input and a 3D mouse for virtual camera control.

With the emergence of interest in the humancomputer symbiosis al so rises the need to find input systems adequate to this paradigm The present research aims to compare three different input systems during the interaction with virtual objects in a wide, immersive mixedreality environment The com mon interaction via keyboard and mouse is compared with two types of interaction mediated by gestural inputs Specifically, we compared the performance and the user experience of participants interacting with a virtual 3D model of a human brain either with keyboard/mouse, or with two different motion sensing devices to input commands: the Microsoft Kinect360 and the KinectOne The results seem to suggest that, although participants showed a better efficiency using the keyboard/mouse, in a high immersive environment, a input system that exploits gestures and body movements without requiring the use of any physical artifact, seems to be the preferred one to use © Springer International Publishing Switzerland 2015.

Motion estimation of multiple depth cameras using spheres

Motion estimation of multiple depth cameras using spheres

Automatic motion estimation of multiple depth cameras has remained a challenging topic in computer vision due to its reliance on the image correspondence problem. In this paper, spherical objects are employed to estimate motion parameters between multiple depth cameras. We move a sphere several times in the common view of depth cameras. We fit the spherical point clouds to get the sphere centers in each depth camera system, and then introduce a factorization based approach to estimate motions between the depth cameras. Both simulated and real experiments show the robustness and effectiveness of our method. © 2014 IEEE.

Hybrid Avatar-Agent Technology - A Conceptual Step towards Mediated "Social" Virtual Reality and its Respective Challenges

Driven by large industry investments, developments of Virtual Reality (VR) technologies including unobtrusive sensors, actuators and novel display devices are rapidly progressing. Realism and interactivity have been postulated as crucial aspects of immersive VR since the naissance of the concept. However, today's VR still falls short from creating real life-like experiences in many regards. This holds particularly true when introducing the "social dimension"into the virtual worlds. Apparently, creating convincing virtual selves and virtual others and conveying meaningful and appropriate social behavior still is an open challenge for future VR. This challenge implies both, technical aspects, such as the real-time capacities of the systems, but also psychological aspects, such as the dynamics of human communication. Our knowledge of VR systems is still fragmented with regard to social cognition, although the social dimension is crucial when aiming at autonomous agents with a certain social background intelligence. It can be questioned though whether a perfect copy of real life interactions is a realistic or even meaningful goal of social VR development at this stage. Taking into consideration the specific strengths and weaknesses of humans and machines, we propose a conceptual turn in social VR which focuses on what we call "hybrid avatar-agent systems". Such systems are required to generate i) avatar mediated interactions between real humans, taking advantage of their social intuitions and flexible communicative skills and ii) an artificial social intelligence (AIS) which monitors, and potentially moderates or transforms ongoing virtual interactions based on social signals, such as performing adaptive manipulations of behavior in intercultural conversations. The current article sketches a respective base architecture and discusses necessary research prospects and challenges as a starting point for future research and development. © 2015 Walter de Gruyter GmbH, Berlin

We present the Really Easy Displays framework (RED), a web-based platform to facilitate spontaneous interaction between devices and applications. RED provides a single abstraction for content and interaction between display types, data streams and interaction modalities, and allows developers to create multi-display applications by enabling the sharing of web document object models (DOMs) across displays. We present lessons learned from using RED in our own research, hands-on workshops with developers and interviews with long-term developers over the course of a year. We provide initial evidence that the use of web-technologies in a framework like RED can mitigate some barriers encountered in by multi-display interaction scenarios, and we propose future work to improve RED.

The goal of this paper is unsupervised face clustering in edited video material - where face tracks arising from different people are assigned to separate clusters, with one cluster for each person. In particular we explore the extent to which faces can be clustered automatically without making an error. This is a very challenging problem given the variation in pose, lighting and expressions that can occur, and the similarities between different people. The novelty we bring is three fold: first, we show that a form of weak supervision is available from the editing structure of the material - the shots, threads and scenes that are standard in edited video;second, we show that by first clustering within scenes the number of face tracks can be significantly reduced with almost no errors;third, we propose an extension of the clustering method to entire episodes using exemplar SVMs based on the negative training data automatically harvested from the editing structure. The method is demonstrated on multiple episodes from two very different TV series, Scrubs and Buffy. For both series it is shown that we move towards our goal, and also outperform a number of baselines from previous works. Copyright is held by the authors.

The current study deals with an empirical approach to an improvement of the patient and doctor relationship of patients undergoing an orthognathic surgery. The aim is the development of an information and communication concept for a smooth and positive treatment for medicine and patient. Such an intervention is a decisive experience and needs to be treated very sensitive. Patients with jaw modulation often suffer from medical-functional as well as psychological problems. Also after surgery, the change of appearance might lead to adjustment disorder. Therefore, a well-elaborated treatment is needed and essential. Retrospective already operated patients were interviewed regarding their expectations, fear, hopes and wishes as well as their individual experience with the surgery. The addition of technical support in form of a 3D scan was also assessed. First results portray a big need of an improved medical education concept as well as an overall positive assessment of the 3D scan. © Springer International Publishing Switzerland 2014.
