The article describes how to integrate cursor sharing features with Daily using vanilla JavaScript, CSS, and daily-js. The demo creates a video call on the left and displays content for participants to review together on the right. When participants position their mouse over the content area, other participants can see their cursor position on their own screens. The implementation uses Daily's "app-message" events to communicate cursor coordinates between participants. It also handles performance and space considerations by only broadcasting data when the cursor has paused for 100 milliseconds. The code sets up a handler for the "joined-meeting" event, which starts monitoring local mouse movement and sends data to other participants when the cursor moves. When a participant leaves the call, their cursor is removed from the DOM. The implementation uses CSS transitions to create a smooth repositioning effect for the remote cursors.
