Abstract: A method for controlling placement of a virtual character includes: displaying a virtual character at a first position in a virtual reality (VR) scene; receiving a first instruction in the VR scene, the first instruction indicating moving the virtual character from the first position by a designated movement; displaying, in response to receiving the first instruction, third indication information as a preview of the designated movement in the VR scene; determining, according to the first instruction, a second position by the designated movement from the first position in response to the first instruction; removing the virtual character from the first position; and placing the virtual character at the second position, the virtual character not appearing between the first position and the second position after being removed from the first position.

Abstract: Embodiments of the present application disclose a method and an apparatus for controlling placement of a virtual character and a storage medium. The method includes: receiving a first instruction in a virtual reality (VR) scene, the first instruction indicating moving a virtual character from a first position by a designated movement; determining a second position by the designated movement from the first position in response to the first instruction; removing the virtual character from the first position; and placing the virtual character at the second position, the virtual character not appearing between the first position and the second position after being removed from the first position.

Abstract: The present disclosure provides a method for controlling a drone, a drone, and a system. The method for controlling a drone comprises: determining operating parameters of a moving platform according to field-of-view images containing the moving platform collected at any two different moments and flight parameters of the drone; calculating a time-varying tracking position of the moving platform based on the operating parameters; controlling the drone to track the moving platform according to the time-varying tracking position of the moving platform; and controlling the drone to perform a landing operation according to a relative position of the moving platform and the drone during tracking. The technical solutions according to the present disclosure have high landing accuracy, rely less on device performance and have high versatility.

Abstract: Aspects of the disclosure provide methods and apparatuses for displaying a gesture in a virtual reality (VR) environment. In some examples, an apparatus for displaying the gesture in the virtual reality (VR) environment includes processing circuitry. The processing circuitry displays a first gesture object corresponding to a state of a virtual hand when the virtual hand does not hold a virtual article. The processing circuitry displays a second gesture object when a ray of the first gesture object intersects the virtual article. The second gesture object indicates that the virtual article is in front of the virtual hand. The ray extends from the virtual hand. The processing circuitry displays a third gesture object in response to a selection instruction. The third gesture object corresponds to a state of the virtual hand when the virtual hand holds the virtual article.

Abstract: There is provided an error correction method for a non-volatile memory. The method includes receiving a codeword read from the non-volatile memory, computing a reliability information for each bit of the codeword received, and performing a reduced-complexity soft-decision decoding (SDD) technique to decode the received codeword. In particular, the SDD technique includes forming a set of test patterns based on the reliability data, and determining whether to perform a HDD of a test pattern in the set of test patterns based on a distance between the test pattern and a candidate pattern. There is also provided an error correction module for a non-volatile memory and a memory system incorporating the error correction module.

Abstract: According to embodiments of the present invention, a decoder for a memory device is provided.
