specific Embodiment approach

[0034] The present invention will be further described below in conjunction with the accompanying drawings. The specific embodiment of the present invention is as follows:

[0035] A wearable device-based multi-appliance control method adopted by the present invention comprises the following steps:

[0036] Step 1, obtain the three-dimensional space information of the user's room and the location of the home appliance, including:

[0037] (1.1) Taking a room with a rectangular planar shape as an example, obtain the length, width and height of the room. For rooms with other shapes, also obtain enough information to describe its three-dimensional shape;

[0038] (1.2) Taking a room with a rectangular planar shape as an example, a certain spatial point in the room (such as a corner) is taken as the origin, and an X-Y-Z three-dimensional right-handed coordinate system is established.

[0039] (1.3) Create the appliance data table of the room. For each smart home appliance in t...

Abstract

A multi-home appliance control method based on a wearable device comprises the following steps of: step 1, obtaining three-dimensional spatial information of a room of the user and locations of home appliances; step 2, placing an ultrasonic ranging device for positioning in the room; step 3, obtaining information of a sensor on the wearable device; step 4, during the training phase, extracting data feature values of the sensor and establishing a feature database and a classifier; and step 5, during the control phase, acquiring and executing a user instruction according to the information of the sensor returned by the wearable device and an auxiliary positioning device. The multi-home appliance control method is simple and natural, avoids the risk of privacy leakage, can calculate the position and orientation of the wearable device by analyzing the inertial measurement unit and the ultrasonic ranging information, and improves the reliability of the control system by accurately determining devices selected by the user in the multi-home appliance scene by using the previously established data table.

Description

technical field [0001] The invention relates to a multi-appliance control method based on wearable devices, in particular to identify user control instructions by fusing inertial sensor information and ultrasonic positioning information to realize low-cost, simple and convenient multi-appliance control without privacy risks. Background technique [0002] Compared with ordinary homes, smart homes not only have traditional living functions, but also provide rich human-computer interaction functions, enabling users to easily obtain information about the environment and equipment, and control the equipment. This feature helps users save unnecessary time consumption and makes home life safer and more comfortable. Because all smart home appliances have been connected to the control server through wireless communication, the control methods using physical buttons or dedicated remote controls in the past are now too cumbersome and difficult to use, because there are more demands on ...
