Anastasia, Nadya, Harlili, Yulianti, Lenny Putri.  2021.  Designing Embodied Virtual Agent in E-commerce System Recommendations using Conversational Design Interaction. 2021 8th International Conference on Advanced Informatics: Concepts, Theory and Applications (ICAICTA). :1–6.
System recommendation is currently on the rise: more and more e-commerce rely on this feature to give more privilege to their users. However, system recommendation still faces a lot of problems that can lead to its downfall. For instance, the cold start problem and lack of privacy for user’s data in system recommendation will make the quality of this system lesser than ever. Moreover, e-commerce also faces another significant issue which is the lack of social presence. Compared to offline shopping, online shopping in e-commerce may be seen as lacking human presence and sociability as it is more impersonal, cold, automated, and generally devoid of face-to-face interactions. Hence, all of those issues mentioned above may lead to the regression of user’s trust toward e-commerce itself. This study will focus on solving those problems using conversational design interaction in the form of a Virtual Agent. This Virtual Agent can help e-commerce gather user preferences and give clear and direct information regarding the use of user’s data as well as help the user find products, promo, or similar products that they seek in e-commerce. The final result of this solution is a high fidelity prototype designed using User-Centered Design Methodology and Natural Conversational Framework. The implementation of this solution is carried out in Shopee e-commerce by modifying their product recommendation system. This prototype was measured using the usability testing method for usability goals efficient to use and user experience goals helpful.

Marru, Suresh, Kuruvilla, Tanya, Abeysinghe, Eroma, McMullen, Donald, Pierce, Marlon, Morgan, David Gene, Tait, Steven L., Innes, Roger W..  2021.  User-Centric Design and Evolvable Architecture for Science Gateways: A Case Study. 2021 IEEE/ACM 21st International Symposium on Cluster, Cloud and Internet Computing (CCGrid). :267–276.
Scientific applications built on wide-area distributed systems such as emerging cloud based architectures and the legacy grid computing infrastructure often struggle with user adoption even though they succeed from a systems research perspective. This paper examines the coupling of user-centered design processes with modern distributed systems. Further in this paper, we describe approaches for conceptualizing a product that solves a recognized need: to develop a data gateway to serve the data management and research needs of experimentalists of electron microscopes and similar shared scientific instruments in the context of a research service laboratory. The purpose of the data gateway is to provide secure, controlled access to data generated from a wide range of scientific instruments. From the functional perspective, we focus on the basic processing of raw data that underlies the lab's "business" processes, the movement of data from the laboratory to central access and archival storage points, and the distribution of data to respective authorized users. Through the gateway interface, users will be able to share the instrument data with collaborators or copy it to remote storage servers. Basic pipelines for extracting additional metadata (through a pluggable parser framework) will be enabled. The core contribution described in this paper, building on the aforementioned distributed data management capabilities, is the adoption of user-centered design processes for developing the scientific user interface. We describe the user-centered design methodology for exploring user needs, iteratively testing the design, learning from user experiences, and adapting what we learn to improve design and capabilities. We further conclude that user-centered design is, in turn, best enabled by an adaptable distributed systems framework. A key challenge to implementing a user-centered design is to have design tools closely linked with a software system architecture that can evolve over time while providing a highly available data gateway. A key contribution of this paper is to share the insights from crafting such an evolvable design-build-evaluate-deploy architecture and plans for iterative development and deployment.

Sharevski, F., Trowbridge, A., Westbrook, J..  2018.  Novel approach for cybersecurity workforce development: A course in secure design. 2018 IEEE Integrated STEM Education Conference (ISEC). :175—180.

Training the future cybersecurity workforce to respond to emerging threats requires introduction of novel educational interventions into the cybersecurity curriculum. To be effective, these interventions have to incorporate trending knowledge from cybersecurity and other related domains while allowing for experiential learning through hands-on experimentation. To date, the traditional interdisciplinary approach for cybersecurity training has infused political science, law, economics or linguistics knowledge into the cybersecurity curriculum, allowing for limited experimentation. Cybersecurity students were left with little opportunity to acquire knowledge, skills, and abilities in domains outside of these. Also, students in outside majors had no options to get into cybersecurity. With this in mind, we developed an interdisciplinary course for experiential learning in the fields of cybersecurity and interaction design. The inaugural course teaches students from cybersecurity, user interaction design, and visual design the principles of designing for secure use - or secure design - and allows them to apply them for prototyping of Internet-of-Things (IoT) products for smart homes. This paper elaborates on the concepts of secure design and how our approach enhances the training of the future cybersecurity workforce.
