Personal tracking devices such as step counters, heart rate sensors, scales, sleep mats, etc. offer a variety of data points. How can these data points be aggregated, interpreted and visualized into meaningful reports? What are key health indicators or factors?
In this thesis you will design personalized, meaningful health reports based on (1) available sensor data, (2) scientific research on health factors and health indicators, (3) information visualization concepts for medical data and (4) expert interviews.

Serious Games are a novel and promising way for motivating people to participate in HCI research. However, the design and development of high-quality games can be a challenging and costly endeavor. At the same time, a large number of video games already exist, which can be customized or extended (e.g. open source games, modding). For this reason, the goal of this topic is to evaluate the suitability of existing video games (commercial, open source, …) for HCI research purposes.
This topic is suitable for applied project-based courses (PR) or for a bachelor thesis. Candidates should have prior experience with video games. Prior experience in game design, game development or game modding is recommended. Prior experience in HCI research methodology is also advantageous.
Trust is an essential pre-requisite and quality of human-computer interaction (HCI), involved in a variety of domains including banking, commerce, communication, identification and authentication, and many more. Despite the importance of trust in HCI, we found existing trust scales to be difficult to use in practical HCI research: they consist of lengthy questionnaires that take a long time to fill and place a significant burden on respondents. Shorter scales or alternative measuring methods are needed.
For this research topic, we suggest that students can investigate the state-of-the-art in the measurement of trust, including the pros and cons of existing trust scales, with regard to practical application in HCI research. Methodologically, this can be achieved by conducting a systematic literature review. The review should follow guidelines such as the PRISMA workflow . For this topic, a primarily qualitative review is likely most suited, but quantitative analysis may also be included to some extent.
As a benefit for students interested in this topic, the suggested research provides an opportunity for learning and practicing systematic review methods – an essential skill for describing the state-of-the-art in any scientific undertaking.

Long, unexpected waiting times can damage the trust a user has placed in a system. This is particularly important in the context of online banking and electronic payment systems, where long waiting times leave users uncertain about the success of a transaction.
One specific research idea is to evaluate and quantify the influence of a payment system’s response time on the users’ perceived trustworthiness of the system. Multiple studies can be conducted based on this research idea by varying the design elements (i.e., UI elements that set expectations regarding waiting time), the risk involved (e.g., the sum involved in a transaction), and the domain (e-banking, p2p payment, e-commerce).

User interface design and branding is known to have a strong influence on how trustworthy a system is perceived by users. This is particularly important in the domain of online banking and electronic payment systems because of the high risk of financial fraud.
One specific, suggested research goal is to evaluate and quantify the influence of design factors (e.g., user interface styling and consistency, branding, shopping seals etc.) on the perceived trustworthiness of an online banking or e-payment system. This topic is not available anymore.
