- Chatterbox Opener: A Game to Support Healthy Communication and RelationshipsWang, Wei-Lu; Haqq, Derek; Saaty, Morva; Cao, Yusheng; Fan, Jixiang; Patel, Jaitun V.; McCrickard, D. Scott (ACM, 2023-10-06)Computer Mediation Communication (CMC) applications are utilized to foster closer relationships between individuals. Various shared experience strategy designs were widely applied to technologies in order to enhance communications and interactions in family relationships. However, there needs to be more research on how shared experience approaches work in different family communication patterns. This paper presents insights into the effectiveness of three types of shared experience approaches for different family communication patterns and design considerations for game design from a diary study of Chatterbox Opener, the game we developed for families and couples to enhance communication orientation.
- CS5604 (Information Retrieval) Fall 2020 Front-end (FE) Team ProjectCao, Yusheng; Mazloom, Reza; Ogunleye, Makanjuola (Virginia Tech, 2020-12-16)With the demand and abundance of information increasing over the last two decades, generations of computer scientists are trying to improve the whole process of information searching, retrieval, and storage. With the diversification of the information sources, users' demand for various requirements of the data has also changed drastically both in terms of usability and performance. Due to the growth of the source material and requirements, correctly sorting, filtering, and storing has given rise to many new challenges in the field. With the help of all four other teams on this project, we are developing an information retrieval, analysis, and storage system to retrieve data from Virginia Tech's Electronic Thesis and Dissertation (ETD), Twitter, and Web Page archives. We seek to provide an appropriate data research and management tool to the users to access specific data. The system will also give certain users the authority to manage and add more data to the system. This project's deliverable will be combined with four others to produce a system usable by Virginia Tech's library system to manage, maintain, and analyze these archives. This report attempts to introduce the system components and design decisions regarding how it has been planned and implemented. Our team has developed a front end web interface that is able to search, retrieve, and manage three important content collection types: ETDs, tweets, and web pages. The interface incorporates a simple hierarchical user permission system, providing different levels of access to its users. In order to facilitate the workflow with other teams, we have containerized this system and made it available on the Virginia Tech cloud server. The system also makes use of a dynamic workflow system using a KnowledgeGraph and Apache Airflow, providing high levels of functional extensibility to the system. This allows curators and researchers to use containerised services for crawling, pre-processing, parsing, and indexing their custom corpora and collections that are available to them in the system.
- Increase Driving Situation Awareness and In-vehicle Gesture-based Menu Navigation Accuracy with Heads-Up DisplayCao, Yusheng (Virginia Tech, 2023-04)More and more novel functions are being integrated into the vehicle infotainment system to allow individuals to perform secondary tasks with high accuracy and low accident risks. Mid-air gesture interactions are one of them. This thesis designed and tested a novel interface to solve a specific issue caused by this method of interaction: visual distraction within the car. In this study, a Heads-Up Display (HUD) was integrated with a gesture-based menu navigation system to allow drivers to see menu selections without looking away from the road. An experiment was conducted to investigate the potential of this system in improving drivers’ driving performance, situation awareness, and gesture interactions. The thesis recruited 24 participants to test the system. Participants provided subjective feedback about using the system and objective performance data. This thesis found that HUD significantly outperformed the Heads-Down Display (HDD) in participants’ preference, perceived workload, level 1 situation awareness, and secondary-task performance. However, to achieve this, the participants compensated by having poor driving performance and relatively longer visual distraction. This thesis will provide directions for future research and improve the overall user experience while the driver interacts with the in-vehicle gesture interaction system.
- Novel In-Vehicle Gesture Interactions: Design and Evaluation of Auditory Displays and Menu Generation InterfacesTabbarah, Moustafa; Cao, Yusheng; Abu Shamat, Ahmad; Fang, Ziming; Li, Lingyu; Jeon, Myounghoon (ACM, 2023-09-18)Using in-vehicle infotainment systems degrades driving performance and increases crash risk. To address this, we developed air gesture interfaces using various auditory displays. Thirty-two participants drove a simulator with air-gesture menu navigation tasks. A 4x2 mixed-model design was used to explore the effects of auditory displays as a within-subjects variable (earcons, auditory icons, spearcons, and no-sound) and menu-generation interfaces as a between-subjects variable (fixed and adaptive) on driving performance, secondary task performance, eye glance, and user experience. The adaptive condition centered the menu around the user’s hand position at the moment of activation, whereas the fixed condition located the menu always at the same position. Results demonstrated that spearcons provided the least visual distraction, least workload, best system usability and was favored by participants; and that fixed menu generation outperformed adaptive menu generation in driving safety and secondary task performance. Findings will inform design guidelines for in-vehicle air-gesture interaction systems.
