Classification: CPC G  H | IPC G

Claim 16:
17. A chip system, wherein the chip system is used in an electronic device comprising a touchscreen, the chip system comprises:
one or more interface circuits; and
one or more processors, wherein an interface circuit and the one or more processors are interconnected through a line, the one or more interface circuits are configured to receive a signal from a memory of the electronic device, and send the signal to the processor, the signal comprises computer instructions stored in the memory, and when the processor executes the computer instructions, the electronic device is configured to
collect a first motion parameter of a user,
obtain a fall confidence of the first motion parameter by comparing the first motion parameter collected by a motion sensor to a first preset fall parameter, wherein the fall confidence of the first motion parameter is used to represent a probability that the first motion parameter is a motion parameter collected when the user falls,
activate a voice assistant and collect a speech command of the user; and, in response to the speech command, perform a speech control event to control the electronic device corresponding to the speech command,
send help-seeking information after the fall confidence of the first motion parameter is greater than a preset confidence threshold
store a model code of a first fall detection model used to determine a fall confidence of a motion parameter, wherein the first fall detection model is an artificial intelligence (AI) model obtained by performing sample training by using a plurality of second motion parameters and a plurality of third motion parameters, and
run the model code of the first fall detection model, to determine the fall confidence of the first motion parameter, wherein the plurality of second motion parameters are motion parameters collected when a plurality of users fall and the plurality of third motion parameters are motion parameters collected when the plurality of users perform a preset interference action.
