Definitions
- the present description concerns the field of sensors, in particular with a view to measuring human activities.
- sensors of different types can be installed jointly to increase the relevance of the information captured in an environment and in particular the precision of possible identification of human activities.
- Such an embodiment thus makes it possible to save the power supply energy of the sensor, as well as the energy of processing data from the sensor if no human presence is detected at least for a certain time.
- the so-called “Wifi Sensing” techniques aim to detect a human presence, or even gestures, by analyzing disturbances induced by the human body on the propagation of Wifi waves typically between a router and a terminal (typically between a gateway of a local network and a connected object in the local network).
- the terminal can be any type of connected object and preferably fixed, for example in a predefined area. In practice, it could be a television or a printer, connected, or even connected bulbs for example, in usually fixed positions.
- this technology is far from being fine enough to be able to be used to identify any specific human activity.
- the simple detection of a presence, or the identification of a posture or movement of a person are not sufficiently informative to identify complex activities of this person, which depend more on a more general context.
- a solution is then proposed here aimed at exploiting the information from Wifi Sensing to optimally activate one or more sensors in the environment, in order to improve the detection of ongoing human activities, and this by controlling energy consumption reasonable use of these sensors, as well as computational consumption of the processes for analyzing human activities in the observed environment.
- the proposed solution implements a method for triggering the analysis of a human activity locally from one or more sensors activated locally, following the detection of a human presence, for example by Wifi Sensing.
- a human activity for example by Wifi Sensing.
- Figure 2 illustrating by way of example the steps of such a process.
- a human presence detection device of the Wifi Sensing device type, which can typically be composed of a router such as a GW gateway (circle in Figure 4) and terminals which can be connected objects (triangles in Figure 4), is configured so that it can cover each zone RO1, RO2, etc. adequately, in terms of detecting human presence.
- the detection coverage between the router and a terminal is generally an ellipse whose foci are the router and the terminal.
- the environmental sensors are “at rest” in step S4 and configured not to measure or transmit any information, if no human presence is detected;
- step S5 The detection of a human presence in step S5 in one of the zones of the environment, via Wifi Sensing, triggers the awakening of the sensors (C11, C12, C13) assigned to this zone (RO1).
- step S6 all of the sensors in the concerned zone RO1 are then “awakened” (in white in Figure 5): a wake-up order is transmitted to each of them via the communication network to which they are connected (for example the local LAN network), this network being used among other things for reporting measurements.
- the sensors associated with the other zones remain at rest (in black in Figure 5);
- the awakened sensors report their measurements to step S7 according to their nominal operating mode and their capacities.
- This information passes through the communication network to which they are connected, for example via the GW gateway and to a SER server for processing the data reported by the sensors and connected to the GW gateway by an extended WAN network.
- an activation device for example in the form of a processing circuit connected to the sensors and which may include for example the GW gateway, transmits the measurements from the sensors to a human activity recognition device, such as the SER server, as soon as a presence has been detected in an area. All sensors associated with this zone are awakened.
- the SER activity recognition device then has access to the data reported by the sensors of the zone and can use them to identify in step S8 a particular human activity in the awakened zone, for example to transmit its inferences to other systems which exploit them;
- the GW gateway includes the detection device as well as the activation device, mentioned above.
- the GW gateway is configured to detect human presence and to activate sensors in the area when human presence is detected.
- An example of recognition of human activities implemented in step S8 can be, without limitation, a machine learning approach (or “machine learning”) of the “Place-based” type, such as as described in the following article:
- the above method works in the same way if several presences are detected in different zones simultaneously: the sensors of each zone concerned are awakened and the information is transmitted, as well as the data measured by the respective sensors, to the human activity recognition system.
- This sensor wake-up process can be instantiated:
- the GW gateway or on other local network equipment such as a connected computer or a user terminal connected to the network for example,
- the recognition of human activities can be executed locally on one or more devices in the network and in another embodiment, the recognition of activities is executed on a remote machine SER in the “cloud”.
- the activation or deactivation of the sensors can be carried out locally (at a unit connected to the local network) or remotely (at a unit connected to to the SER server for example).
- Figure 6 illustrates by way of example the first embodiment in which an activation device, here in the form of a processing circuit (for example integrated into the GW gateway), can include:
- a first interface INT1 for RF radio frequency communication (for example via Wifi connection) with various connected objects in the environment,
- a second interface INT2 for controlling the sensors C11, C12, C13, etc., C21, C22, C23, etc., arranged in the environment, on the one hand to activate or deactivate at least one set of appropriate sensors ( C11, C12, C13) in the event of detection of human presence or absence in an area (R01) to which this set of sensors is assigned, and on the other hand to receive the data from these sensors and transmit them for example to a remote processing server SER via an extended WAN network to which a third communication interface is connected INT3,
- the subject of the present description can find applications for the recognition of human activities in connected environments and having radio frequency detection means (for example Wifi), for example in “smart home” or “smart home” installations.
- radio frequency detection means for example Wifi
- smart home Connected Home, Protected Home, etc.
- intelligent tertiary buildings such as connected professional premises or even nursing homes or hospitals
- augmented reality spaces for example
