Abstract: Embodiments of this application provide an animation effect display method and an electronic device, and relate to the field of electronic technologies. According to the animation effect display method provided in an embodiment of this application, before an animation effect is displayed, a UI thread of an application, or a rendering thread of the application, or a rendering process determines controls whose properties change in duration of the animation effect, and determines properties of controls on an interface of each frame, and then the rendering thread of the application or the rendering process generates, based on the properties of the controls on the interface of each frame, a bitmap corresponding to the interface of the frame. Because the properties like sizes and locations of the controls on the interface of each frame are determined before the animation effect is displayed, the UI thread does not need to perform measurement, layout, and drawing and recording (recording) on the interface of each frame, so that display of the animation effect is not affected by UI thread blocking.

Abstract: There is provided a method and apparatus for tracking a device. The tracked device may be a wearable device worn by a user participating in an athletic activity. An anchor device is positioned with respect to a playing area and receives signals from the tracked device. The anchor device estimates the position of the tracked device by measuring a distance and direction of the signal, and decodes the signal to obtain measurements taken by the tracked device. The position and the measurements are combined to produce tracking data for the device.

Abstract: A method to correct a haptic output, the method including sending, at a device, a reference tactile signal to a haptic actuator and recording, using a sensor associated with the haptic actuator, an output signal from the haptic actuator. This output signal could be provided, along with the reference tactile signal to an engine at the device, which could be used to determine regions of perceptual distortion from the output signal and the reference tactile signal. Specifically, a perceptual similarity measure could be determined which could be used to generate an adapted signal to reduce and equalize the perceptual distortion, where the adapted signal could be provided to the haptic actuator to control adaptation or equalization of distortions.
