About
Cardio-metabolic risk factors include obesity, physical inactivity, smoke, alcohol abuse, high blood lipids or sugar and arterial hypertension. Systems for self-learning and self-monitoring may help people improve and maintain a healthy lifestyle through tailored suggestions about diet, weight control, physical activity, fatigue,stress.
SEMEOTICONS exploits the human face as an indicator of individual's health status and translates signs obtained from the face using contactless sensors into measures and descriptors to be automatically evaluated by a an interactive smart mirror. This "Wize Mirror" extracts descriptors from videos, images and gas concentration signals and integrates them in a virtual model used to compute and trace the evolution of an individual's wellness index. A health diary enables each individual to evaluate and personally relate his/her lifestyle to his/her well-being. Coaching messages are provided, in relation to the evolution of the wellness index and of each descriptor, to provide useful suggestions on correct lifestyle self-monitoring.
The purpose of this study is assess the accuracy of the information derived from the Wize Mirror in expressing the health status of the individual.
The reproducibility and repeatability study will evaluate whether measurements are stable over short time spans and whether they are influenced by meals light and temperature conditions.
To verify whether the Wize Mirror is able to detect variations in physical and emotional health status with appropriate lifestyle changes, the validation study will cross-check measurements from the Wize Mirror against reference clinical tests at enrolment and after 3 months of personalized suggestions for healthy behavior.

Full description
Cardio--metabolic (CM) risk is a cluster of risk factors indicative of a patient's overall risk for cardiovascular diseases (CVD), the leading cause of morbidity and mortality worldwide and type-2 diabetes. CM risk factors include obesity, physical inactivity, smoke, alcohol abuse, abnormal lipid metabolism, hyper-glycaemia and arterial hypertension.
Educational programs and lifestyle interventions represent effective tools to improve the risk profile but they need time consuming and expensive counselling and supervision of various health professionals . A rational alternative to intensive individual coaching is the use of systems for self-learning and self-monitoring, to help people change and maintain a healthy lifestyle through tailored suggestions about nutrition, weight control, physical activity, fatigue, and stress.
SEMEOTICONS exploits the human face as an indicator of individual's health status and translates signs obtained from the face into measures and descriptors to be automatically evaluated by a computerized application, an interactive smart mirror, which seamlessly integrates contactless sensors, such as 3D optical sensors, a multispectral camera, gas detection sensors, and microphones and a touch-screen interface for user's interactions and output visualization.
This "Wize Mirror" collects data in the form of videos, images and gas concentration signals, and extracts a number of biometric, morphometric, colorimetric, and compositional descriptors that represent individual's facial signs. The integration of such descriptors constitute a virtual model used to compute and trace the evolution of an individual's wellness index. A health diary about this index enables each individual to evaluate and personally relate his/her lifestyle to his/her well-being. Coaching messages are provided, in relation to the evolution of the wellness index and of each descriptor to provide useful suggestions on correct lifestyle self-monitoring.
The purpose of this study is assess the accuracy of the information derived from the Wize Mirror in expressing the health status of an individual.
Arm 1 Reproducibility and repeatability study (to be performed at the French site Lyon only).
The reproducibility and repeatability study will evaluate whether Wize Mirror measurements are influenced by meals, light and temperature conditions in 6 healthy volunteers Data will be acquired during 4 modules corresponding to different use conditions of the mirror
To assess whether measurements are stable over short time spans one of the 6 volunteers will undergo a last visit for the repeatability study in the fasting state. Wize Mirror measurements will be performed at T0 under artificial lights and at environment temperature (18-20°C) for 10 consecutive times with a 30 minutes interval between acquisitions.
During each visit the following Wize Mirror measurements will be performed:
Arm 2 Validation study. The validation study will check data measured from the Wize Mirror against reference clinical tests in 60 healthy volunteers. To verify whether the Wize Mirror is able to detect variations in physical and emotional health status with appropriate lifestyle changes, measurements will be cross-checked at enrolment and after 3 months of personalized suggestions for healthy behavior.
Healthy volunteers will undergo at recruitment the following for user profiling for baseline CM risk
Medical history,
Physical examination: anthropometric measurements (body height, body weight, waist circumference, hip circumference) and vital signs (heart/respiratory rate, blood pressure)
Body composition (lean mass, fatty mass) by air displacement pletysmography
Energy expenditure by indirect calorimetry
Peripheral venous blood sampling: hemoglobin, creatinine,Total, HDL, LDL cholesterol, triglycerides, gamma glutamyl transferase, aspartate aminotransferase (AST), alanine aminotransferase (ALT), bilirubin, glucose, insulin, HbA1c
Skin accumulation of Advanced Glycation End Products (AGEs)
Peripheral arterial tonometry for endothelium-dependent vasodilatation
Pulse oxymetry for oxygen saturation
Exhaled gas sampling
Psychological , knowledge and nutritional tests
Data acquisition to derive computational descriptors for Wize Mirror functioning will include image (still pictures, videos) acquisition in visible light and infrared band before and after thermal stimulation at 42° C and Exhaled gas sampling using the "Wize Sniffer". During each visit the following Wize Mirror measurements will be performed:
Healthy volunteers will then undergo periodically (minimum time interval 2 weeks) face image acquisition, exhaled gas sampling and they will fill through the Wize Mirror screen lifestyle questionnaires till week 12 (end of study). At the end of study visit they will repeat baseline assessments and fill in a questionnaire to evaluate Wize Mirror ease of use and acceptability.
The changes in Wize Mirror measurements obtained at baseline and end of study will be correlated with changes in body weight, waist circumference and Fatty liver index. Relationship with quality of life, or other well-being questionnaire SCORE, standard biochemistry and specific tests will be also assessed.
