Abstract: Embodiments of the present disclosure are directed to a speech interaction method executed at an electronic device, a speech interaction apparatus, and a computer readable storage medium. The method includes receiving an image sequence of a user from an image capturing apparatus coupled to the electronic device. The method also includes detecting a change in a head feature of the user from the image sequence. After that, the method includes determining whether the change in the head feature matches a predetermined change pattern. The method further includes causing the electronic device to enter an active state in response to determining that the change in the head feature matches the predetermined change pattern, the electronic device in the active state being capable of responding to a speech command of the user.

Abstract: The present application discloses a method and apparatus for operating a field-programmable gate array (FPGA) board in a driverless vehicle. The method according to a specific embodiment includes: collecting driving scenario information on a driving scenario of the driverless vehicle; determining, based on the driving scenario information, a speed at which the driverless vehicle executes a computing operation in the driving scenario; comparing the speed with a speed threshold; switching a working mode of the FPGA board in the driverless vehicle executing the computing operation to reduce power consumption of the FPGA board, in response to the speed being lower than the speed threshold. This embodiment implements the adaptive adjustment of the working mode of the FPGA board, thereby reducing the overall power consumption.
