Abstract: This application discloses a palm-based human-computer interaction method performed by a computer device. The method includes: obtaining, by a palm-based interaction device, sensor data of a palm that is captured by at least two proximity sensors, the at least two proximity sensors being disposed in an array on the palm-based interaction device; recognizing a hovering interaction action of the palm based on the sensor data of the palm that is captured by the at least two proximity sensors; and performing a response operation for the hovering interaction action. This application provides a new interaction manner. A proximity sensor recognizes a hovering interaction operation performed by a palm, so that a user can control a palm-based interaction device without touching or any physical contact. This improves efficiency of interaction.

Abstract: A palm recognition device is provided, and belongs to the field of the electronic device technologies. The palm recognition device includes a housing, a PCB, and a camera. The PCB and the camera are both located inside the housing. The housing has an image capturing window, and a projection of the camera on the image capturing window deviates downward relative to a central point of the image capturing window.

Abstract: A container has a main body and an easily-detached lid. The main body has an opening, and a main body engaging element is disposed around the edge of the opening. The lid has a lid engaging element corresponding to the main body engaging element for allowing the lid to engage with the main body via the main body engaging element and the lid engaging element. A wall is disposed at the outer boundary of the lid, and the wall has at least one tilting portion.

Abstract: The disclosure relates to a container with an easily-detached lid, wherein the container has a main body and a lid. The main body has an opening, and a main body engaging element is disposed around the edge of the opening. The lid has a lid engaging element corresponding to the main body engaging element for allowing the lid to engage with the main body via the main body engaging element and the lid engaging element. The container with an easily-detached lid is characterized in that a wall is disposed at the outer boundary of the lid and the wall has at least one tilting portion.
