Such systems are employed by companies in order to satisfy their existing customers and attract new ones. However, many small or medium companies do not possess adequate customer data to generate satisfactory recommendations. To solve this problem, we propose that the companies should generate recommendations based on a joint set of customer data. For this purpose, we present a privacy-preserving collaborative filtering algorithm, which allows one company to generate recommendations based on its own customer data and the customer data from other companies. The security property is based on rigorous cryptographic techniques, and guarantees that no company will leak its customer data to others. In practice, such a guarantee not only protects companies' business incentives but also makes the operation compliant with privacy regulations. To obtain precise performance figures, we implement a prototype of the proposed solution in C++. The experimental results show that the proposed solution achieves significant accuracy difference in the generated recommendations.","PeriodicalId":200122,"journal":{"name":"2012 International Conference on Collaboration Technologies and Systems (CTS)","volume":"133 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117271247","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The rapid evolution of cloud infrastructures, portable devices and multimedia services has enabled cooperation among strangers in online environments that lack quality of service guarantees. Group members experience delays and inconsistencies in the shared state. Previous research on delays focuses on tightly-coupled tasks and assumes that individual and group interests are aligned. In reality, individual participation in a group depends on how a participant weighs the value and the cost of cooperation. That tension is well captured in mixed-motive tasks (e.g., a social trap). A study was conducted, where 15 groups performed a loosely-coupled task that simulates social traps. Group members experienced a gradual degradation of system performance in the form of complex delays. Groups exhibited different adaptation patterns to the changes in the system behavior. There is no guarantee that group adaptation will always keep the status quo. System interventions are needed to maintain group dynamics.","PeriodicalId":200122,"journal":{"name":"2012 International Conference on Collaboration Technologies and Systems (CTS)","volume":"03 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127452450","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most existing operator control units (OCUs) are designed for tele-operation of a single robot and require the constant attention of the operator. As the role of robots increase in important fields such as bomb disposal; intelligence, surveillance, and reconnaissance (ISR); and search and rescue it becomes critical to improve this ratio by enabling multiple robots to be monitored and controlled by a single operator. Toward this goal we have developed the Situations, Actions, Goals, and Environment (SAGE) interface, which utilizes numerous techniques for maintaining operator situation awareness by aiding the operator's perception, comprehension, and projection when controlling a team of ground robots. Techniques that we developed include dynamic view control, event detection and prioritization, uncertainty display, view-invariant markers to make state information globally visible, and animations to avoid jarring distractions. SAGE's interface was automated making it completely hands off, thus the operator could save interaction time for critical tasks such robot tasking. SAGE was deployed by Team Michigan as part of its OCU suite in the 2010 Multi-Autonomous Ground-robotic International Challenge (MAGIC). Team Michigan won this competition in part because of its innovative OCU designs, including SAGE, that enabled two operators to control 14 robots simultaneously - a 1-to-7 operator to robot ratio, higher than any other team.","PeriodicalId":200122,"journal":{"name":"2012 International Conference on Collaboration Technologies and Systems (CTS)","volume":"16 9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128184918","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Murphy","doi":"10.1109/CTS.2012.6261117","DOIUrl":"https://doi.org/10.1109/CTS.2012.6261117","url":null,"abstract":"This paper presents a model of “comfortable distance” that captures the factors and conditions known to affect personal space in human-human and human-robot interactions, as well as any identified relationships between them. In the first known human-robot interaction (HRI) survey on approach distance, 19 papers were reviewed and the “comfortable distance” model was synthesized with three distinct types of inputs: environmental conditions, personal factors, and agent factors. Five environmental conditions (lighting, ceiling height, indoor/outdoor, room size, and barrier height) and seven personal factors (gender, age, mood, personality, pet ownership, robot experience, and sitting/standing) structure the model, with four agent factors (angle of approach, height of agent, speed of approach, and gaze) used as tuning parameters to produce behaviors with appropriate distances. Currently, HRI researchers generally focus on one factor at a time (e.g., approach angle or approach speed), without considering the previous work in adjacent fields, such as psychology and other social sciences. This has resulted in environmental factors being ignored by the HRI community. The “comfortable distance” model is a new tool for HRI researchers and is expandable so that it can incorporate new factors as they are identified. This survey will inform researchers about factors which had been previously overlooked in the field of HRI and will allow future researchers to consider the impact of identified variables to create more complete experiments.","PeriodicalId":200122,"journal":{"name":"2012 International Conference on Collaboration Technologies and Systems (CTS)","volume":"117 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124326220","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
