ISGT - Optimal privacy-by-Design Strategy for user demand shaping in smart grids
2020 IEEE Power & Energy Society Innovative Smart Grid Technologies Conference (ISGT), 2020Co-Authors: Ramana R. Avula, Tobias J. OechteringAbstract:In this work, we propose an optimal privacy-by-Design Strategy using an energy storage system (ESS) that is capable of shaping the user demand to follow a time-varying target profile. In addition, we consider the ESS usage cost due to its energy losses and capacity degradation. We measure the privacy leakage in terms of the Bayesian risk. The proposed Strategy is computed by solving a multi-objective optimization problem using the Markov decision process framework. With numerical simulations using real household consumption data and a lithium-ion battery model, we study the trade-off between the achievable Bayesian risk, the variations in the user demand from the target profile and the energy storage cost. The results show that by trading-off some privacy, the variations in the user demand can be reduced while improving the battery lifetime.

Design Strategy of optimal user interface for each user and system using analytic hierarchy process
Systems Man and Cybernetics, 2008Co-Authors: Takako Nonaka, Yuta Uesugi, Tomohiro HaseAbstract:This paper proposes a method of selecting Design strategies for user interfaces for audio-visual (AV) remote controllers based on the analytic hierarchy process. In this method, the Design policy for the optimum user interface (UI) is selected on the basis of the function and scale of the AV system and the user's knowledge. This paper proposes a new model with six evaluation criteria-functional choice, operating procedure, knowledge of the AV equipment, system structure, user behavior and psychology. As a final option, we have decided our Design Strategy for the user interface-visual, functional, sensor and input and output, and interactive oriented. In order to verify the proposed model, a prototype of the AV remote controller operated by a 32-bit RISC microcomputer was built. Then the experiment was carried out using two cases: one where a beginner operates a small-scale system and the other where an experienced AV user operates a large-scale system. The result showed that the optimum UI Design Strategy was the UI with importance given to interactive and visual aspects in the case of the beginner with the UI emphasizing the functional aspect in the case of the professional. This indicates that, like the results obtained from the previously proposed model, the newly proposed model is expected to enable UI Design befitting more directly the actual situation of AV systems that tend to become larger in scale and multifunctional.

IV - Surfacing Repetitive Design Strategy with Visualization Tool
2017 21st International Conference Information Visualisation (IV), 2017Co-Authors: Hsin-yi Huang, Teng-wen ChangAbstract:Designers tend to have repetitive Design Strategy in the process without notices. The elements setting the interactive function is to conform the user requirement and it can improve the user experiences. Although it has many information recorded on the paper, but via the think-aloud we can find out many implicit information. Then, we can go through the sketch to understand how we define the visualize graphic nodes and find out their implicit mode. By surfacing such behaviors, Designers can focus on effective Design strategies rather than repetitive Design.
