User experience over time with conversational agents: case study of woebot on supporting subjective well-being

Demirci, Hatice Merve
Technological advancements re-shaped user-product interactions by enabling people to make conversation with interactive systems. This new form of interaction led designers to create a new type of user interface: Conversational User Interface (CUI). Expensive psychological therapy fees and people’s increased awareness related to importance of well-being attracted the interactive system developers to create a domain specific Conversational Agent, which is particularly focusing on psychological terapy and has CUI. In order to maintain user engagement and sustain usage, design of such systems is important. However, existing design guidelines for Conversational Agents are limited and focus on business functions of these agents; however, conversational experience should be the main focus for designers to sustain user engagement and support people’s well-being. The aim of this research is to explore design qualities of Conversational Agent’s that focuses on enhancing people’s subjective well-being, to accomplish sustained usage and engagement with the conversational agent and propose guidance for designing such agents. For this purpose, interviews were conducted with users. Woebot, a Conversational Agent, which is designed for promoting people’s subjective well-being was selected as a case for the study and evaluated by 16 participants. The interpretations of the participants were obtained by semi- structured and in-depth interviews. Through analysing the results of the interviews, improvement suggestions are presented regarding system operations and functionality in terms of its attractiveness, perspicuity, effectiveness, stimulation, dependability, efficiency and novelty. Lastly, the study provides insights that would affect users’ engagement and overall experience


Intelligent student assessment and coaching interface to web-based education-oriented intelligent experimentation on robot supported laboratory set-ups
Motuk, Halil Erdem; Erkmen, Aydan Müşerref; Erkmen, İsmet; Department of Electrical and Electronics Engineering (2003)
This thesis presents a framework for an intelligent interface for the access of robotsupported remote laboratories through the Internet. The framework is composed of the student assessment and coaching system, the experimentation scenario, and the associated graphical user interface. Student assessment and coaching system is the main feature of a successful intelligent interface for use during remote experimentation with a robot-supported laboratory setup. The system has a modular structure employing artifi...
A usability evaluation framework and a case study on a supplier portal system
Babayiğit, Elif Fatma; Şen, Tayyar; Department of Industrial Engineering (2003)
The goal of this thesis is to provide a usability evaluation framework in the area of e-procurement technologies and a case study on this base. A survey of the concepts of human computer interaction, usability and usability evaluation techniques is carried out. Additionally current e-procurement technologies are explored and specifically a Company̕s Supplier Portal System which was employed in year 2003, as an e-procurement technology for the procurement of direct goods, is taken into consideration. Pointin...
Demonstratives in the context of a collaborative problem solving task
Büyüktekin, Faruk; Çakır, Murat Perit; Temürcü, Ceyhan; Department of Cognitive Sciences (2018)
Multimodal user interfaces have become increasingly important. They are being used in various applications such as computer games, online education, simulations, and assistive technology. Such interfaces now can make use of inputs coming from different modalities such as speech and eye gaze. This multimodality enables situated dialogue between users and artificial agents, encouraging collaborative language use. Naturally, people need to refer to entities in the surrounding environment using demonstratives d...
Exploring The Potentials of Voice-Based Conversational Agents for The Elderly: Beyond a Pragmatic Perspective
Şahin, Hilal; Töre Yargın, Gülşen; Günay, Aslı; Department of Industrial Design (2023-1-27)
Speech, the fundamental basis of human communication, is now enabling interaction between humans and machines. Correspondingly, the acceptance of Voice-based Conversational Agents (VCAs) by different age groups is remarkably rising. The aging population and events like COVID-19 have led to increased attention on elderly users in academic research, which focuses mostly on their declining mental and physical abilities. The aim of this thesis is to examine the impact of values, hedonic aspects, and routines of...
Interoperability among event-driven microservice-based systems
Bayramçavuş, Ali; Doğru, Ali Hikmet; Kaya, Muhammed Çağrı; Department of Computer Engineering (2022-2)
This work presents our proposed solution to provide interoperability among systems that have event-driven microservice architecture using different middleware technologies. Publish/subscribe technology is an essential part of event-driven architectures, and these technologies, specifically through Kafka and RabbitMQ, are targeted in this work. Our interoperability tool proposes a way to solve interoperability problems, as a microservice platform allowing more than two systems to work together. Experiments, ...
