The progression of neurodegenerative disorders and the increasing number of elderly people intensifies the need of institutional care, which contrasts with the desire of most elderly and patients to live independently at home. The rapid evolution of assistive technology offers new possibilities in providing medical professionals preventive services in real-time. Therefore, the main focus of this study is on the individual sensors and how they can be combined to one unobtrusive system to assess the human behaviour and daily activities during day and night in an instrumented apartment in healthy participants.
The higher prevalence of age-associated neurodegenerative disorders (e.g. Parkinson, Alzheimer), is in line with a steady increase of the average life expectancy in Switzerland. With the progression of neurodegenerative disorders and the increasing number of elderly people, the need for institutional care intensifies, which contrasts with the desire of most elderly and patients to live independently. The rapid evolution of assistive technology offers new possibilities in providing medical professionals preventive services in real-time. An extended stay in the hospital could influence independent ageing negatively and thus, monitoring has great potential to prevent critical events. In this study, the main focus is on the individual sensors and how they can be combined to one unobtrusive system. In addition, to get an understanding which parameters of the sensors are important and how the data can be extracted and processed (algorithms). Therefore, the aim of this study is to validate the accuracy to assess human behaviour and daily activities during day and night by unobtrusive sensors in an instrumented apartment in healthy participants.

| Monitoring by unobtrusive sensors | Other | During the study the behavior of daily activities will be monitored by unobstructive sensors. Most of the sensors will be mounted on the wall or on furniture with direct sight to the participant and thus will not have any physical contact, except some wearables during the stay in the apartment and at home (e.g. watch, mobile polysomnography). |
| Measure | Description | Time Frame |
|---|---|---|
| Heart rate (Vital parameters) | The heart rate will be continuously measured by pressure sensors, radar sensors, infrared camera, galvanic sensor and polysomnography (gold standard). | 1 Week / Continuously |
| Respiration rate (Vital parameters) | The respiration rate will be continuously measured by pressure sensors, radar sensors, infrared camera, galvanic sensor and polysomnography (gold standard). | 1 Week / Continuously |
| Oxygen saturation (Vital parameters) | The oxygen saturation will be continuously measured by pressure sensors, radar sensors, infrared camera, galvanic sensor and polysomnography (gold standard). | 1 Week / Continuously |
| Systolic / Diastolic blood pressure (Vital parameters) | The blood pressure will be continuously measured by pressure sensors, radar sensors, infrared camera, galvanic sensor and polysomnography (gold standard). | 1 Week / Continuously |
| Skin conductance (Vital parameters) | The skin conductance will be continuously measured by pressure sensors, radar sensors, infrared camera, galvanic sensor and polysomnography (gold standard). | 1 Week / Continuously |
| Measure | Description | Time Frame |
|---|---|---|
| 3D Model (Coordinates of the joints over time) of the participant in the apartment (Movement parameters) | The pose will be assessed continuously by pressure sensors, radar sensors, accelerometer, gyroscope, motion tracking (gold standard), lidar sensors, piir sensors. | 1 Week / Continuously |
| Measure | Description | Time Frame |
|---|---|---|
| Usability | The usability of the sensor system will be assessed by the System usability scale (SUS). The score range is between 0 and 100, whereas the higher score means higher usability. | Each day / 7x |
| Doors open and closed (Activities of daily living) |

| Cognition 1 | Cognition will be assessed by the Montreal Cognitive Assessment (MoCA). Scores of the MoCA range from 0 to 30, with a score of 26 and higher generally considered normal. | Measured on the first day / 1x |
| Cognition 2 | Cognition will be assessed by the Mini-Mental State Examination (MMSE). Scores of the MMSE range from 0 to 30, with a score of 25 and higher generally considered normal. | Measured on the first day / 1x |
