Abstract: A method and an apparatus for switching an ECG measurement mode, a wearable device, and a computer-readable storage medium. The method includes: receiving two successive pieces of PPG data transmitted by an optical heart-rate sensor, where the PPG data is generated by a contact between a measurement electrode and a skin; calculating a difference between the two received pieces of the PPG data; and controlling switching among measurement modes based on the difference, where the measurement modes comprise an ECG wristband mode and an ECG chest-lead mode Manual switching of an ECG measurement mode is avoided with simple operations, high efficiency, and more intelligence.

Abstract: Disclosed are a method for positioning and tracking, an apparatus, a terminal device, and a computer-readable storage medium. The method includes: capturing an image containing a plurality of light spots by the image acquisition device; the plurality of light spots are generated by each of multiple light sources on the handle emitting invisible light; determining first identification data of target light sources corresponding to the plurality of light spots in the image in the multiple light sources; determining a positional relationship between a plurality of the target light sources according to the first identification data, and calculating a first distance parameter between the handle and the VR head-mounted device according to the positional relationship; and converting the first distance parameter into a spatial coordinate of the handle to perform positioning and tracking of the handle.
