One major challenge of networked control systems (NCSs) is how to guarantee the stability of all control loops in the presence of communication delay. Addressing this problem, the control community generally focuses on designing new controllers or adjusting the sensor's sampling period to adapt to the network. Alternatively, we address the problem from the communication perspective in this paper. To this end, we consider all control loops as network applications (i.e. keeping controllers, sensors and actuators unchanged), and develop a control-aware network scheduler to handle the control performance degradation caused by communication delay. We further investigate how to interpret the Quality-of-Control as a Quality-of-Service (QoS) measure to guide the scheduler design. The proposed QoS metric represents the instantaneous Linear Quadratic Gaussian (LQG) cost of a control system, which quantifies the energy deviation of the system to its optimal condition. By leveraging the proposed QoS metric, we develop a novel QoS-driven uplink scheduler. Simulation results confirm the efficiency of the proposed scheduler for networked control services.","PeriodicalId":147917,"journal":{"name":"2017 IEEE International Symposium on Haptic, Audio and Visual Environments and Games (HAVE)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131912127","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}

Haptics technologies allow the operator to interact with the simulation environment using the sense of touch. In this paper we investigate three facets for realistic simulation with periodontists: (1) a custom grip is designed to attach dental instruments to the haptic interface in order to enhance the grip, (2) two haptic interfaces are utilized to simulate haptic feedback with both the dental instrument and the mirror instrument, and (3) a finger rest mechanism based on parallel manipulation is used for the intraoral fulcrum during probing. A haptic-based simulation system, named the Haptodont, is developed to evaluate the three facets of realism. A subjective evaluation is conducted with five dental experts to collect more information about perceptions, insights, and experiences to shape the second generation requirements and design for the Haptodont system. Future work will focus on further development and quantitative usability testing (with both dental experts and students) with the goal to improve the educational experience, outcomes and skills of clinicians/students.","PeriodicalId":147917,"journal":{"name":"2017 IEEE International Symposium on Haptic, Audio and Visual Environments and Games (HAVE)","volume":"263 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132388019","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}

One major challenge in this context is how to maximize the user's quality-of-experience (QoE) while ensuring at the same time the stability of the global control loop in the presence of communication delay. In this paper, we propose a dynamic control scheme switching strategy for teleoperation systems, which maximizes the QoE for time-varying communication delay. In order to validate the feasibility of the proposed approach, we perform a dedicated case study for a virtual teleoperation environment consisting of a one-dimensional spring-damper system, and conduct extensive subjective tests under various delay conditions for two control schemes : (1) teleoperation with the time-domain passivity approach (TDPA), which is highly delay-sensitive but supports highly dynamic interaction between the operator and a potentially quickly changing remote environment; (2) model-mediated teleoperation (MMT), which is tolerable to relatively larger communication delays, but unsuitable for quickly changing, highly dynamic remote environments. For both schemes, we use recently proposed extensions, which incorporate perceptual data reduction to reduce the required packet rate between the operator and the teleoperator. One key contribution of this paper lies in the exploration of the intrinsic relationship among QoE, communication delay and the control schemes which provides a fundamental guidance, not only to this research, but also to the future joint optimization of communication and control for time-delayed teleoperation systems.","PeriodicalId":147917,"journal":{"name":"2017 IEEE International Symposium on Haptic, Audio and Visual Environments and Games (HAVE)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125420938","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}
