Summary: This case study describes the findings from our exploration on content user experience for next-generation live TV and VOD (Video-on-Demand) services. First, we introduce our background study on new trends in the TV industry. Based on this study, we list several keywords that characterize the content experience for next-generation TV. We then describe our interviews with six professionals working in content production. These interviews were conducted to verify our derived characteristics, and to collect the thoughts of these experts on the contribution of UX to future content production. Our study led us to a new research topic we call "Augmented Content," which we believe has significant potential to provide content UX for next-generation television services.

Summary: Photo Polling (PP) Wall is an interactive polling system in which community members can express and share their ideas on certain subjects through public displays, mobile devices, and social network services. The PP wall system will be a combination of multimedia services (sound effect), public display, mobile web service and client & server. With these features, we propose the PP wall system as an experimental platform for developing other interactive contents.

Summary: The NextGen Cockpit Situation Display (CSD), developed by NASA Ames's Flight Deck Display Laboratory, provides advanced flight control functionalities and traffic/weather displays to pilots [1]. Traditionally, the user operates with the CSD using a computer mouse and receives only visual feedback about the controlling actions. In this work, we integrate force feedback in the Route Assessment Tools of the CSD, where the user can manage the flight plan to resolve conflicts in real-time. A spring force, with a variable stiffness coefficient, was used to model the force feedback with its strength varying proportionally to the overall path length. Force display was provided as an indicator of the effort required to deviate from the optimal path to assist the user in decision making. The force feedback models were evaluated on a software testbed created on Microsoft Foundation Class with the Novint Falcon haptic-feedback input device.

Summary: This study investigates whether assigning a caregiving role to a robot or to its human interactant has psychological effects on the quality of human-robot interaction (HRI). College students interacted with a social robot in a between-subjects experiment (N = 60) with two manipulated conditions: one where the robot played the role of an ophthalmologist (with participants serving as patients) and one where participants played the role of the ophthalmologist (with the robot serving as the patient). Results suggest that being a recipient of caregiving acts leads users to form more positive perceptions of the robot than being an ostensible caregiver to the robot. Results also indicate that perceived benefit of being in a relationship with the robot mediates the effects of the caregiving role on relationship satisfaction with -- and trust towards -- the robot while feelings of social presence mediate the effects on humanlike-ness and intelligence of the robot. These findings demonstrate the applicability of the Computers Are Social Actors (CASA) paradigm to the context of HRI.

[5] Modeling semantic relations between visual attributes and object categories via dirichlet forest prior KM track: classification and semantic methods / Chen, Xin / Hu, Xiaohua / Zhou, Zhongna / An, Yuan / He, Tingting / Park, E. K. Proceedings of the 2012 ACM Conference on Information and Knowledge Management 2012-10-29 p.1263-1272

ACM Digital Library Link

Summary: In this paper, we deal with two research issues: the automation of visual attribute identification and semantic relation learning between visual attributes and object categories. The contribution is two-fold, firstly, we provide uniform framework to reliably extract both categorical attributes and depictive attributes. Secondly, we incorporate the obtained semantic associations between visual attributes and object categories into a text-based topic model and extract descriptive latent topics from external textual knowledge sources. Specifically, we show that in mining natural language descriptions from external knowledge sources, the relation between semantic visual attributes and object categories can be encoded as Must-Links and Cannot-Links, which can be represented by Dirichlet-Forest prior. To alleviate the workload of manual supervision and labeling in image categorization process, we introduce a semi-supervised training framework using soft-margin semi-supervised SVM classifier. We also show that the large-scale image categorization results can be significantly improved by combining automatically acquired visual attributes. Experimental results show that the proposed model achieves better ability in describing object-related attributes and makes the inferred latent topics more descriptive.

Summary: The present research aims to provide insight into social compensatory friending on social network sites by investigating the effects of self-esteem and self-consciousness on number of friends in the context of Facebook use. It was hypothesized that Facebook users low in self-esteem, when compared with high-self-esteem individuals, would engage in friending more actively and thereby accumulate a large number of friends as a way to compensate for the deficiency in self-esteem. We also hypothesized that the relationship between self-esteem and number of Facebook friends would vary depending on the levels of public self-consciousness. Data were collected from a college student sample in the United States (N = 234) based on an online cross-sectional survey. The results supported the hypothesis on social compensatory friending, demonstrating a negative association between self-esteem and number of Facebook friends. Furthermore, the data yielded support for the hypothesized moderating role of public self-consciousness in social compensatory friending: the negative association between self-esteem and number of Facebook friends was significant only for Facebook users who are high in public self-consciousness but not for those who are low in public self-consciousness. Implications for understanding social network site users' friending behavior in light of social compensation motives are discussed.

ACM Digital Library Link

Summary: A 2 x 2 between-subjects experiment was conducted to examine the effects of the type of artificial agent (robot vs. computer) and the role of the agent (ally vs. enemy) on people's perceptions and evaluations of the agent when playing a video game. Participants perceived that playing the game with a robot was more enjoyable and easier than playing with a computer. Regardless of the agent type, participants reported that playing the game was more enjoyable when the agent played as an ally rather than as their opponent. Implications of notable findings are discussed.

[8] The effects of immersive tendency and need to belong on human-robot interaction LBR highlights / Kim, Ki Joon / Park, Eunil / Sundar, S. Shyam / del Pobil, Angel P. Proceedings of the 7th International Conference on Human-Robot Interaction 2012-03-05 p.207-208

ACM Digital Library Link

Summary: Do individual differences in dispositional behavioral tendencies, such as immersive tendency and need to belong, play a significant role in human-robot interaction? To answer this question, the present study conducted a 2 x 2 between-subjects experiment to examine the effects of immersive tendency (high vs. low) and need to belong (high vs. low) on individuals' perceptions of a social robot. Preliminary data analyses revealed that participants with a higher level of immersive tendency and need to belong showed greater attachment and trust towards the robot, and were more satisfied with their relationship with the robot than participants with a lower level of immersive tendency and need to belong. In addition, participants with a higher level of immersive tendency experienced greater feelings of social presence. Implications of notable findings are discussed.

[9] Perspective hierarchical dirichlet process for user-tagged image modeling Queries, questions and tags mining / Chen, Xin / Hu, Xiaohua / An, Yuan / Xiong, Zunyan / He, Tingting / Park, E. K. Proceedings of the 2011 ACM Conference on Information and Knowledge Management 2011-10-24 p.1341-1346

ACM Digital Library Link

Summary: In this paper, we proposed a perspective Hierarchical Dirichlet Process (pHDP) model to deal with user-tagged image modeling. The contribution is two-fold. Firstly, we associate image features with image tags. Secondly, we incorporate the user's perspectives into the image tag generation process and introduce new latent variables to determine if an image tag is generated from user's perspectives or from the image content. Therefore, the model is able to extract both embedded semantic components and user's perspectives from user-tagged images. Based on the proposed pHDP model, we achieve automatic image tagging with users' perspective. Experimental results show that the pHDP model achieves better image tagging performance compared to state-of-the-art topic models.

[10] The effects of screen-size and communication modality on psychology of mobile device users Works-in-progress / Kim, Ki Joon / Sundar, S. Shyam / Park, Eunil Proceedings of ACM CHI 2011 Conference on Human Factors in Computing Systems 2011-05-07 v.2 p.1207-1212

ACM Digital Library Link

Summary: Does screen-size matter in mobile devices? There appears to be a move toward larger screens, with recent launches of Apple's iPad and Samsung's Galaxy Tab, but do these devices undercut the perceived mobility and affect user attitudes toward the technology? To answer these and related questions, the present study examines the effects of screen-size and communication modality (text vs. video) on mobile device users' perception of mobility and content as well as attitudes toward technology acceptance. Preliminary data from a between-subjects experiment show that smaller screen-size elicited greater perceived mobility while larger screen-size was key to greater enjoyment. News story in video format played a crucial role in providing greater enjoyment and newsworthiness of the news story while news in text format was perceived to be easier to use on a mobile device. Design implications and limitations are discussed, as we prepare for a constructive replication.

[11] The effect of robot's behavior vs. appearance on communication with humans Late-breaking reports/poster session / Park, Eunil / Kong, Hwayeon / Lim, Hyeong-taek / Lee, Jongsik / You, Sangseok / del Pobil, Angel Pasqual Proceedings of the 6th International Conference on Human-Robot Interaction 2011-03-06 p.219-220

ACM Digital Library Link

Summary: This study explores the effect of the robot's appearance vs. behavior (voice and gestures) on the way it is perceived as a machine-like instead of a human-like robot. A between-subjects experiment with four conditions was conducted. Results suggest that both the robot's behavior and appearance are important but, if they are contradictory, the robot's behavior is more powerful than the robot's appearance in the perception of the robot as more machine-like or human-like.

[12] A probabilistic topic-connection model for automatic image annotation KM track: data pre- and post-processing / Chen, Xin / Hu, Xiaohua / Zhou, Zhongna / Lu, Caimei / Rosen, Gail / He, Tingting / Park, E. K. Proceedings of the 2010 ACM Conference on Information and Knowledge Management 2010-10-26 p.899-908

Summary: The explosive increase of image data on Internet has made it an important, yet very challenging task to index and automatically annotate image data. To achieve that end, sophisticated algorithms and models have been proposed to study the correlation between image content and corresponding text description. Despite the success of previous works, however, researchers are still facing two major difficulties that may undermine their effort of providing reliable and accurate annotations for images. The first difficulty is lacking of comprehensive benchmark image dataset with high quality text descriptions. The second difficulty is lacking of effective way to represent the image content and make it associate with the text descriptions. In our paper, we aim to deal with both problems. To deal with the first problem, we utilize Wikipedia as external knowledge source and enrich the ontology structure of ImageNet database with comprehensive and highly-reliable text descriptions from Wikipedia articles. To address the second problem, we develop a Probabilistic Topic-Connection (PTC) model to represent the connection between latent semantic topic in text description and latent patterns from image feature space. We compare the performance of our model with the currently popular Correspondence LDA (Corr-LDA) model under the same automatic image annotation scenario using cross-validation. Experimental results demonstrate that our model is able to well represent the connection between latent semantic topics and latent patterns in image feature space, thus facilitates knowledge organization and understanding of both image and text descriptions.

Summary: The study presents the AVALANCHE visualization test-bed for sensemaking in ill-structured problem domains. AVALANCHE allows the users to develop and frame hypotheses, analyze the hypotheses in the experimental domain, and provide cases for simulation experiments. The visualization and sensemaking support module in AVALANCHE provides human-computer interface and visualization supports. Validation experiments using groups aided with visualization and support tools and groups with no aiding was performed on two open-ended sensemaking cases provided by a military subject matter expert. Statistical analyses revealed mean performance differences in plan accuracy, plan time, and number of cue prompts between aided and unaided groups across task scenarios. In general, the aided group had the highest mean plan outcome accuracy, low planning time, and the least number of prompts. The intention is to extend the study to collaborative sensemaking tasks to address the effects of negotiation on team planning time, cue prompting frequencies, and different types of cue prompting modalities.

[14] Exploit the tripartite network of social tagging for web clustering Poster session 2: DB track / Lu, Caimei / Chen, Xin / Park, E. K. Proceedings of the 2009 ACM Conference on Information and Knowledge Management 2009-11-02 p.1545-1548

ACM Digital Library Link

Summary: In this poster, we investigate how to enhance web clustering by leveraging the tripartite network of social tagging systems. We propose a clustering method, called "Tripartite Clustering", which cluster the three types of nodes (resources, users and tags) simultaneously based on the links in the social tagging network. The proposed method is experimented on a real-world social tagging dataset sampled from del.icio.us. We also compare the proposed clustering approach with K-means. All the clustering results are evaluated against a human-maintained web directory. The experimental results show that Tripartite Clustering significantly outperforms the content-based K-means approach and achieves performance close to that of social annotation-based K-means whereas generating much more useful information.

Summary: We investigated the adhesion between gold thin film and poly (methyl methacrylate) (PMMA) and poly (vinylidene fluoride-co-hexafluoropropylene) (P(VDF-co-HFP)) substrates with the aim of imparting electrical conductivity to plastic optical fibers (POFs). The two polymers were used as the core and the cladding of POF, respectively. Gold thin film of 50nm thickness was deposited by ion sputtering onto the polymers and also POF. Several approaches, which were well known to be effective in enhancing adhesive strength between gold and polymers, were applied in this study: introduction of polar functionality on the substrate surface by plasma treatment, buffer layer insertion, and physical surface roughening. The variation of wettability and adhesion with plasma conditions was investigated through water contact angle measurement and cross hatch cut test. Even though the contact angles of substrates were decreased after Ar or O₂ plasma treatment, irrespective of the polymer type, the adhesion of polymers with gold layer was very poor. The Ti buffer layer of 5nm thickness, which was deposited between PMMA substrate and gold layer, did not contribute to improve the adhesion. However, P(VDF-co-HFP) substrates with rough surface of 13.44nm RMS shows 3B class adhesion to gold from the cross hatch tape test. The gold-coated POF showed the electrical conductivity of 1.35×10³Scm^-1 without significant optical loss. The result may be used for developing a medical device capable of simultaneously applying electrical and optical stimulus.

Summary: Transportation agencies have been considering the use of a purple sign background color to denote that the roadway is tolled. Prior studies have shown a driver preference for a unique color for the toll road category. Concerns about the legibility of purple signs have been raised due to their brightness and contrast ratio with a white legend. The current study performed an evaluation of the legibility and recognition of purple and green freeway guide signs during daytime and nighttime driving in the Houston, TX area. Forty-eight participants drove an instrumented vehicle in open traffic and read traffic signs along a toll road with purple signs on one segment and green signs on another. Results showed no significant difference in legibility distance between signs with purple and green backgrounds. An analysis of recognition distances for advance guide signs marking ramps to the toll road also showed no difference between purple and green signs. These results support the implementation of this new color without any loss in legibility.

Summary: In this study, we investigated the effect of solvent etching and physical treatment on the sidelighting of POF, even qualitatively. Even though the two were effective in making sidelight POF, the tensile properties of POF were decreased as a result of surface damaged during the treatment. We also investigated how to overcoat side-illuminating POF in order not to be broken during weaving process to make side-illuminating POF fabric. In the view of clarity and interfacial adhesion with POF, AC-100 based on acrylic polymer was chosen for overcoating material. However, tensile strength of notched POF was rather decreased even after overcoating, maybe due to toluene used as diluent, which is also solvent for the core of POF, i.e., PMMA.

Summary: Throughout history, paintings have had a static perspective, as determined by the artist. Nowadays, viewers are not passive anymore. This proposal focuses on dynamic painting, and active audiences. Magic Asian Art allows viewers to enjoy dynamic Asian painting, and furthermore, each audience recreates the same painting according to their personal preference or the impression of a painting. It is quite similar that conductor conducts an orchestra for the same music differently. We extract viewer's intension based on the emotional status or impression of the painting by using gaze tracker and the painting will be more dynamic and fun. Magic Asian Art is neither movies by cinematographer, nor video games by an algorithm, but novel interactive painting media by each user.

Summary: As individuals and enterprises interconnect via wide area networks, workflows that span them seamlessly will become increasingly valuable. It is likely that heterogeneous participants -- humans, applications, organizations -- that are physically dispersed over such networks will share workflows that cut across organizational and geographic boundaries. We address the problem of designing a distributed workflow infrastructure that supports such scenarios in the presence of heterogeneous workflow systems and components. We present RainMaker, a workflow framework based on a service requestor/service provider execution model. RainMaker defines a core set of abstract interfaces that can be implemented by distributed workflow components. Together, the RainMaker execution model and interfaces provide a foundation for the interoperability of workflow systems and components.

Summary: A mining environment is one of the most complex and unstructured in the manufacturing industry. In order to minimize the problems associated with these characteristics, recent strategies in mining operation are to automate the task performance and to design mining machines that are "intelligent." These strategies, among other things, will require that the human operators and the machine interact and collaborate to perform tasks in a symbiotic manner. To achieve this, a prototype dialogue-based interaction platform has been developed. The platform known as OASIP is a knowledge-based system driven by the operator-planned actions and behaviors known as intentions. OASIP is an adaptive system which exploits several sources of environmental knowledge from built-in blackboard cells.

Summary: This paper describes a blackboard (BB) system developed for human interaction with a remotely operated mining machine. The BB architecture was chosen because of its ability to alter and/share information stored on any blackboard cell with other cells in a dynamic and cooperative mode. The BB discussed here is based on hierarchical organization of basic patterns of information sharing by multiagents that cooperate to solve a given problem.
