A smart wearable device includes a wearable device body, a signal control module, a gas detection module, a signal recording module, and a vibration generating module. The gas detection module can detect a gas concentration of a predetermined gas surrounding the wearable device body so as to obtain a gas concentration signal. The signal recording module can record a plurality of gas concentration values that are provided by the gas concentration signal, and record a plurality of gas-measuring time points that are respectively configured for obtaining the gas concentration values. The vibration generating module can generate a prompt signal according to the gas concentration value provided by the gas concentration signal, and generate a beat signal according to a user setting value. Therefore, the smart wearable device can provide relevant information corresponding to the gas concentration signal, the prompt signal, and the beat signal for a user.

A method and system for simulation of deformation of elastic materials are disclosed herein. A matrix-free geometric multigrid method utilizing a direct coarse grid discretization is presented for the solution of linear systems resulting from an octree discretization of the equations of corotational linear elasticity. The diagonal component of the stiffness matrix needed for the multigrid smoother is calculated without generating the stiffness matrix. The use of an incomplete linear octree data structure supports the efficient simulation of objects with complicated boundaries. Furthermore, the method is robust to large deformations, making it suitable for character skinning applications in computer animation.

In some embodiments, the method comprises: receiving metadata associated with a video; receiving a request to present the video; causing the video to begin buffering; generating, using a hardware processor, an animation based on the metadata; causing the animation to be presented until a predetermined amount of the video has been buffered; and causing the video to be presented upon buffering the predetermined amount of the video.

An electronic device displays a messaging interface. The messaging user interface includes a search affordance and a conversation between a user of the device and another user. While displaying the messaging interface, the device detects activation of the search affordance. In response, the device ceases displaying the messaging interface and displays a search interface. The search user interface includes a search field and categorized content items. The categorized content items include a content item stored on the device and a content item from the Internet. While displaying the search interface, the device detects selection of a first item in the categorized content items; and, afterwards, displays the first item in the conversation. The device transmits the first item to the device that corresponds to the other user in the messaging session. The other user's device displays the item in a conversation that corresponds to the messaging session.
