Community based activity monitoring and alert solution for elderly people living at home

Smart Scout

Community based activity monitoring solution for elderly people staying at their own home.




Pascal RENOU - Tina NIKO


with the general aging of population, x% percent of people choose to stay at home alone instead of using supervised facilities such as retirement homes or hospitals. With staying alone at home there is a risk that if something critical happens, this is not communicated immediately and the time is lost in providing help.

The general property of aging population is that oftentimes they do not have Internet at home and they are reluctant to modify their habits. These two factors limit the use of Internet-based and wearable solutions.



Install low power/low cost sensor-based monitoring system in the house. The system will learn the weekly/monthly movement pattern of the resident and raise an alarm if the current behavior substantially differs. The alarm will first warn the actual resident and, if not answered, will be propagated further to the designated neighbors. In case it is not answered by the neighbors, it will raise to the next severity level such as warning the local medical service, social workers, or relatives.

Besides alarm handling, the community-based approach also fosters motivation to remain healthy for individuals by means of ranking. The home device will display resident’s activity ranking compared to his designated community members, encouraging him to stay active.

Components overview

Home device –

Essentially sensor board which will be installed in the residence and measure the activity and report it regularly (every 15 min) to the cloud. The device will be equipped with the following:

-          Four digit screen, which will display the ranking of the resident (1 - 9) among his neighbors, his own activity score (00-99), and, in the case of the alarm, the ID of the affected neighbor.

-          Colored lamp – green meaning the measured activity is normal. Red means there is an active alarm.

-          Button – Can be used to turn on/off the system. It can also be used to report or reset an alarm.

-          Beeper – an alternative way to signal an alarm, to help users with visual impairments.

Cloud –

the engine which:

-          Maintains data about residents, including the list of designated relationships between the resident and his neighbors. Each resident can select a list of neighbors sorted by priority with which he would participate in the ranking computation and alarm management.

-          Processes reading from the device, and composes a model for normal behavior

-          Reports periodically to the device the following 3 values in 4 digits.

o   Dig 1- Resident’s own ranking, values form 0 to 9. Value 0 means the resident is not participating in the ranking system or he has no neighbors. Value 1 means he is at the top of the list, with value 9 meaning he is showing the lowest activity.

o   Dig 2 - In the case of alarm, the ID of the resident who raised an alarm.

o   Dig 3&4 - Resident’s own movement score from 0 (worst) to 99 (best)

o   Example 1- value 2 0 8 5, means that current resident is ranked as number 2 among his neighbors, there is no current alarm, and he is enjoying a high score of 85 for his activity level.

o   Example 2- value 0 0 0 0, means the current user triggered an alarm.

o   Example 3- value 2 3 8 5, means the same as the first example, except that the neighbor with id 3 received an alarm, and did not reset it. That is why the current resident is being informed about his neighbor’s alarm.

-          Raises alarm if the current reading is beyond normal range or matches a predefined alarm activity. This corresponds to message displayed as 0 0 0 0

-          Manages the timer once the alarm is set. If the timer expires before the reset message is received, adapts the new timer to a lower value, and either send the message to the next neighbor or escalates to the next level.

-          Provides data for visualization on the front end.

Web interface/Mobile/App –

front end to provide the following visualizations:

1.       Graph showing excepted activity level (model) with the current activity

2.       Map showing participating residents and their current status visually, for example house icons ranging from green to red background colors.
