Research

At this moment, there are two main research threads in our lab: educational human-data interaction (EDU-HDI) and socio-spatial human-data interaction (SS-HDI).

Here are 5 examples of our current research:


1. Analysis of Learning Behaviors (EDU-HDI)

Improving teaching and learning practices can be extremely difficult without proper understanding of relevant learning behaviors.

We design, develop, and evaluate HDI methods, systems and tools that support teachers and students gain proper understanding of learning-relevant behaviors by employing data mining and information visualization techniques. This work is based on our collaboration with Learning Analytics Center.

2. Learning Analytics for All (EDU-HDI)

An increasing number of communities are super-aged. However, most of the existing digital learning-support environments cannot easily support older adults in recurrent and lifelong learning contexts.

We design, develop, and evaluate HDI methods, systems and tools that support older adults by employing user-centered approaches and sensor-based analytics to make learning tools and materials easier to use and more effective for people over the age of 65.

3. Recommender Systems in University Environments (EDU-HDI)

Existing course recommendation systems for online learning environments could not fully support students in university environments due to the inherent differences of the online and physically-based learning environments.

We design, develop, and evaluate HDI methods, systems and tools that recommend elective courses to university students by employing recommender algorithms and systems that are aware of relevant constraints and resources in university environments, thereby supporting students find the right courses to take.

4. Mobile and Situated Crowdsourcing (SS-HDI)

Data Science requires a surprisingly large amount of human labor collecting, labeling, preparing, and using data, which is a particularly critical issue when we are to deal with real-world data and services in specific spaces and situations. This necessiates development of efficient approaches to crowdsource data-related labor in different spaces and situations.

We design, develop, and evaluate HDI methods, systems and tools that support efficient mobile and situated crowdsourcing in public spaces and local communities to collect useful data without requiring too much human labor. We do this by employing crowdsourcing methods, algorithms, and tools that are aware of relevant contexts and models.

5. Contextual Reminders (SS-HDI)

Providing useful feedback to the users at the right time, at the right place, and in the right way may require knowledge and wisdom that machines are not good at acquiring. Although existing Data Science approaches tend to treat humans merely as data sources, realizing effective data-driven feedback mechanisms may necessiates an alternative perspective on humans as the participants and/or social partners rather than the monitored.

We design, develop, and evaluate HDI methods, systems and tools that can deliver useful safety-related contextual reminders to the members of a local community. We do this by involving locals at diffent levels of the system to elicit and integrate their local knowledge and wisdom into the system’s information space. This is based on participatory design, and employs an active crowdsourcing technique as well as IoT-based ‘invisible’ user interface design. We thus facilitate participation by non tech-savvy local residents in the design as well as the data collection process of contextual reminders.
