MuC 2024 Workshop - AI and Health: Using Digital Twins to Foster Healthy Behavior

Workshop on AI and Health @ MuC 2024, Karlsruhe, Germany

This workshop brings researchers together to discuss and explore how artificial intelligence (AI) can be used to improve general health. During our workshop at the MuC conference, we will focus on three main areas: developing ethical AI health recommendations, exploring how smart technologies in our homes can influence our health habits, and understanding how different types of feedback can change our health behaviors. The workshop aims to be a space where various research areas meet, encouraging a shared understanding and creating new ways to use AI to encourage healthy living. By focusing on real-world applications of AI and digital twins, we seek to guide our discussions toward strategies that have a direct and positive impact on individual and societal health.

Topics of Interest

In this workshop we will solicit submissions that cover a broad range of topics related to the overall theme. In particular, we are interested in work that addresses any of the following topics:

  • AI-Based Health Recommendations:  Exploring the efficacy and ethical considerations of utilizing artificial intelligence to provide real-time, personalized health recommendations in everyday contexts. This means looking closely at how we can use AI to give people personalized health advice in an ethical and helpful way. It involves issues such as data privacy, user consent, and the seamless integration of these systems into daily life to encourage positive health behavior while mitigating potential harm. Moreover, it is crucial to examine the social, psychological, and ethical implications of deploying such technologies.

  • Smart Home Devices for Health:  Investigating the role of smart home devices and digital artifacts in communicating both healthy and unhealthy behaviors to users. We want to dive into smart health technologies at home and in our daily lives to look at how everyday devices can tell us about the healthiness of our behavior and help us make better choices on a daily basis. Digital artifacts may communicate progress toward daily physical activity goals or predict shifts in users' body composition or weight, based on dietary choices and physical activity levels over recent weeks or months.

  • Feedback Mechanisms:  Assessing both explicit and implicit techniques for delivering health-related feedback and evaluating their respective impacts on user behavior and well-being. We will examine how different ways of giving health feedback can influence people's individual behavior and overall health. Explicit feedback mechanisms may involve notifications that offer healthy activity recommendations for daily life (e.g., disembarking the train one stop early to complete the journey on foot) or dietary choices (e.g., presenting the consequences of food selections at cafeterias or grocery stores during the decision-making process). Such explicit methods may also offer detailed explanations via explainable AI and forecast the potential long-term outcomes of these choices, both positive and negative. Conversely, implicit feedback incorporates nudges seamlessly into daily routines, without overtly presenting the user with recommendations; for example, by choosing a route that avoids fast-food restaurants known to tempt the user.

  • Human-in-the-Loop Systems:  Examining the integration of practitioners and health experts within human-in-the-loop systems to guide users toward healthier behavioral choices. This exploration can involve the display of user data, such as dietary intake and physical activity levels, to health consultants or personal trainers. Utilizing tools such as dashboards, experts could work collaboratively to create personalized plans for the user or patient, identifying opportunities for increased activity in daily routines, or avoiding situations that trigger unhealthy habits. Feedback can subsequently be provided to the AI system to enhance its learning capabilities and situational recognition. Improvements to the system should be based on user data and expert input while ensuring that privacy and user autonomy are maintained.

  • MR/VR in Health Interventions:  Assessing the potential of Mixed Reality (MR) and Virtual Reality (VR) applications in delivering effective health interventions and recommendations. Looking toward the distant future, we envision employing MR and VR in daily life to illustrate the consequences of various habits. MR could, for example, be applied to communicate certain details about potential decisions in-situ. VR on the other hand could be used to simulate a certain result of a long-term intervention.

  • Motivation for Sports and Exertion:  Investigating how exergames and AI algorithms that adjust exercise difficulty can effectively motivate individuals for sports and physical exertion. This includes the integration of gamification and AI components to address different player types. A possible application is the dynamic adjustment of exergame difficulty based on user performance to maintain a targeted heart rate for effective training. Further, an AI health assistant can aim to identify opportune moments in everyday life to prompt users to engage in physical activities in the first place.

  • Dietary Behavior and Digital Twins:  Evaluating methodologies for tracking nutritional intake as a basis for digital twins and examining how AI tools can foster and communicate healthier food choices. By improving tracking possibilities with AI the data about the user will improve allowing the creation of better user models and improved recommendations. Further, novel approaches to model humans including their health-related behavior is a crucial challenge.

  • AI-Driven Time Management and Health Routines:  Investigating the impact of AI-driven suggestions on daily life routines on overall health and well-being. This includes also research tools, methods, and guidelines to evaluate such AI-driven applications. Given the specific context and the goal of long-term improvement, researchers are in need of creating new tools and methods. Additionally, guidelines and lessons learned from evaluations provide a valuable source for future research endeavors.

  • Explainability of AI-driven recommendations:  Providing means to explain recommendations in health-related scenarios is important to create trust in the recommendations. Users should be able to understand and question the reasoning behind AI-driven recommendations so that a certain level of explainability (e.g., why a specific recommendation is provided) is available and the AI system is not a black box.
