Abstract: A method and a system for rendering video images in virtual reality (VR) scenes are provided. The method includes providing a video image at a current time point, dividing the video image at the current time point into a plurality of sub-regions, inputting image feature information of the sub-regions and acquired user viewpoint feature information into a trained attention model for processing to obtain attention coefficients of the sub-regions indicating probability values at which user viewpoints at a next time point fall into the sub-regions, rendering the sub-regions based on the attention coefficients of the sub-regions to obtain a rendered video image at the current time point, inputting the attention coefficients of the sub-regions and the image feature information of the sub-regions into a trained user eyes trajectory prediction model for processing, obtaining user eyes trajectory information in a current time period, dividing, for video images at subsequent time points within the current time period, the video images at the subsequent time points into a plurality of sub-regions, calculating attention coefficients of the sub-regions in a video image at each of the subsequent time points within the current time period respectively based on the user eyes trajectory information in the current time period, and rendering the corresponding sub-regions based on the attention coefficients of the sub-regions to obtain a rendered video image at each of the subsequent time points.

Abstract: The disclosure provides a data transmission method and a data transmission device. The data transmission method includes allocating corresponding Orthogonal Frequency Division Multiple Access (OFDMA) sub-channels to respective target neighbor devices in a wireless personal area network (WPAN) based on a determination that a current data transmission scenario of the WPAN is a specific data transmission scenario and transmitting data in the preset data transmission scenario to the respective target neighbor devices through the OFDMA sub-channels. Moreover, according to the data transmission method, an OFDMA transmission mechanism is supported in a SoC system under a wireless local area network and the wireless personal area network, and the OFDMA transmission mechanism is provided in data transmission scenarios with a large amount of data, thereby improving the data transmission rate and saving the data transmission time.

Abstract: An electronic device is provided. The electronic device includes a memory configured to store at least one instruction, and at least one processor where the at least one processor is configured to execute the instruction to obtain voice data from a conversation of at least one user, convert the voice data to text data, determine at least one parameter indicating characteristic of the conversation based on at least one of the voice data or the text data, adjust a condition for triggering intervention in the conversation based on the determined at least one parameter, and output a feedback based on the text data when the adjusted condition is satisfied, wherein the adjustment of the condition includes adjusting a first and a second threshold based on change of the at least one parameter.
