We introduce a natural notion of boundary of a proper metric space that is large and invariant under quasi-isometries. A point in this boundary is an equivalence class of quasi-geodesics that can be quasi-redirected to each other. It turns out the sublinearly-Morse boundary is a topological subspace of the quasi-redirecting boundary. We will also show that the quasi-redirecting boundary is idential to the Bowditch boundary in certain cases. This is a joint work with Yulan Qing.
