Personal informatics applications have been gaining momentum with the introduction of implicit data collection and alert mechanisms on smart phones. A need for customized design of these applications is emerging and studies on tailoring UI design based on the personality traits of users are well established. This poster investigates how various affordances(More)
While motivational affordances are widely used to enhance user engagement in "gamified" apps, they are often employed en masse. Prior research offers little guidance about how individuals with different dispositions may react-positively and negatively-to specific affordances. In this paper, we present a survey study investigating the relationships among(More)
The Intensive Care Unit (ICU) has the highest annual mortality rate (4.4M) of any hospital unit or 25% of all clinical admissions. Studies show a relationship between clinician cognitive load and workflow, and their impact on patient safety and the subsequent occurrence of medical mishaps due to diagnostic error - in spite of advances in health information(More)
In our research group, we are currently carrying out several empirical research studies to inform the design of future personal informatics (PI) systems. These studies include projects investigating the use of gamification elements to encourage engagement based on a user's personality type, varying levels of feedback during day-to-day PI use, and(More)
Recovery from brain injury is a complex and longitudinal process consisting of clinical recovery, illness management, and personal recovery. Lack of initiatives to create awareness about expected recovery and tools for helping patients understand their progress make the personal recovery journey challenging and frustrating. In this paper, we discuss results(More)
Indiana University School of Informatics and Computing / Department of Human-Centered Computing Associate Professor / Ph.D. Students / MS Student Background and Aim: The ICU holds the critically ill who require continuous and coordinated monitoring and frequent intervention. ICUs have the highest annual mortality rate of any hospital unit (12-22%),(More)
BACKGROUND In the United States, over 15 million informal caregivers provide unpaid care to people with Alzheimer disease (AD). Compared with others in their age group, AD caregivers have higher rates of stress, and medical and psychiatric illnesses. Psychosocial interventions improve the health of caregivers. However, constraints of time, distance, and(More)
