Close2U, an electronic device application, has been developed by researchers at the Complutense University (UCM) and the University of Zaragoza (UZA) to monitor cancer patients’ physical and mental health using gamification.

Users answer a series of daily questions about their mood and where they are experiencing pain. In return, the app rewards them in the form of advice or songs, resources intended to increase their motivation.

“The use of gamification enables more continuous monitoring of cancer patients by obtaining frequent information about their mood. Among other things, this lets us know if they are depressed, stressed or in pain,” explained Iván García-Magariño, a researcher in the Department of Software Engineering and Artificial Intelligence at the UCM.

The study was conducted in collaboration with the Spanish Cancer Association (Spanish initials: AECC), primarily at its branch in Teruel, where patients tested the app.

Researchers from both universities have reported development of the app and the results obtained in the Journal of Biomedical Informatics and Journal of Healthcare Engineering.

Exchange of resources among patients

For example, for the question “How did you sleep?”, users mark a point on a horizontal line between the two extremes “very badly” and “very well,” while for the question “Where in your body are you experiencing pain?”, the screen displays an image of a body on which patients mark areas affected by pain.

The information obtained from their answers is sent to a hospital or association physician.

In return, patients are rewarded with advice or songs which “are intended to amuse and entertain them, and which they can also share with other cancer patients to provide mutual support,” observed García Magariño.

He also noted that the researchers were working on incorporating the app on other devices such as smart furniture or watches. “We

Millions of people turn to their mobile devices when seeking medical advice. They’re able to share their symptoms and receive potential diagnoses through chatbot-based symptom-checker (CSC) apps.

But how do these apps compare to a trip to the doctor’s office?

Not well, according to a new study. Researchers from Penn State’s College of Information Sciences and Technology have found that existing CSC apps lack the functions to support the full diagnostic process of a traditional visit to a medical facility. Rather, they said, the apps can only support five processes of an actual exam: establishing a patient history, evaluating symptoms, giving an initial diagnosis, ordering further diagnostic tests, and providing referrals or other follow-up treatments.

“These apps do not support conducting physical exams, providing a final diagnosis, and performing and analyzing test results, because these three processes are difficult to realize using mobile apps,” said Yue You, a graduate student in the College of Information Sciences and Technology and lead author on the study.

In the study, the researchers investigated the functionalities of popular CSC apps through a feature review, then examined user experiences by analyzing user reviews and conducting user interviews. Through their user experience analysis, You and her team also found that users perceive CSC apps to lack support for a comprehensive medical history, flexible symptom input, comprehensible questions, and diverse diseases and user groups.

The findings could inform functional and conversational design updates for health care chatbots, such as improving the functions that enable users to input their symptoms or using comprehensible language and providing explanations during conversations.

“Especially in health and medicine, [another question is] is there something else we should consider in the chatbot design, such as how should we let users describe their symptoms when interacting with the chatbot?”
