This app accompanies the book “Cell-to-Cell Communication: Cell Atlas – Visual Biology in Oral Medicine” and allows the user to experience the process of bone resorption in augmented reality. AR Osteoclasts draws you into the microcosm of osteoclasts right above the bone surface. In the augmented display, you are zoomed in to the level at which an osteoclast precursor cell appears to be the size of a hand. You investigate the bone resorption process from all sides by moving around the augmented display on top of your book page and you interact with cells to learn more about their function.
