Computer Vision App Assists Mental Health Clinicians

Researchers from Carnegie Mellon University have been developing MultiSense technologies to automatically sense human non-verbal behaviors such as facial expressions, eye gaze, head gestures, and vocal non-verbal behaviors like the voice and its tenseness. The goal is to assist clinicians working with mental health patients with their diagnosis and treatments of mental disorders such as depression, anxiety, PTSD, schizophrenia, and autism. Louis-Philippe Morency, PhD and colleagues describe that one of the primary algorithms, from a computer-vision perspective, is facial landmark detection. It automatically identifies the position of 68 “landmarks” or key points on the face. These were defined over the years as being reliable to track over time. Examples are the eyebrow positions, contour of the mouth, the eye corners, and jaw contours. These are cornerstones for a later stage of analysis because knowing their current shapes really helps understand and recognize the facial expression. This is coupled with things like head-tilt and eye-gaze estimations. The goal of the software is not to diagnose depression, that’s always the job of the doctor. We’re building these algorithms as decision support tools for the clinicians so that they can do their assessments. But from an academic perspective, we do want to know how well these behavioral markers are correlating with the assessment of clinicians. We’ve done this work and seen around a 78% correlation. So it’s not 100%, but our data is significant. We’re definitely heading in the right direction!                Source: MedGadget...

MIT Develops Temporary Skin Tattoo Interfaces

MIT Media Lab partnering with Microsoft Research, has unveiled DuoSkin, a project that uses temporary tattoos as connected interfaces that can be used in a variety of ways. DuoSkin, as described by MIT researchers, is a fabrication process that allows for the creation of customized functional devices that can be attached onto the skin of users. The project originated from the growing trend of metallic temporary tattoos, making DuoSkin a combination of existing fashion with useful functions in the connected world. Duoskin...

World Health Organization Publishes mHealth Guidelines

The mHealth Technical Evidence Review Group of the World Health Organization (WHO) has released a new mHealth research checklist for the reporting of studies involving mobile health interventions. The mHealth evidence reporting and assessment (mERA) checklist offers a standardized approach to reporting of mHealth studies that clearly defines the intervention (content), as well as the context in which the intervention was tested, and how it was done (technical features). The goal is to improve the quality of reporting & facilitate replication. BMJ. 2016 Mar 17;352:i1174....

Adaptive Text Messaging as an Adjunct to Clinical Care

A study in the Journal of Medical Internet Research described a study that was conducted in families with a preschool-aged child recently diagnosed as overweight or obese by their primary care provider. Parents were coached on skills to promote healthy lifestyle behaviors using cognitive behavior therapy. All of the skills were supported using tailored, adaptive text messaging. The novel feature of this program is that the parents helped to create messages that “spoke to them.” Using an automated software application messages were delivered based on desired content, timing, and frequency to support behavior change or skills practice at home. Results a significant increase in parental beliefs in their ability to engage in healthy lifestyles and self-reported healthy lifestyle behaviors. Furthermore, all parents reported the program as being useful, and indicated a desire to have their pediatric primary care incorporate the text messaging as an additional form of communication. JMIR Vol 4, No 1 (2016): Jan-Mar...
