Try-on is the only AR use case that touches your face, so the trust bar is the highest in all of ecommerce. Furniture goes in a room. Try-on goes on your body. - The categories that work: beauty (shade matching on a real face), eyewear (face mapping frames where they would sit), increasingly jewelry and watches. - Full-outfit fashion try-on is the hard one: bodies vary more than faces, and the tech knows it. - Check accuracy in bad lighting, because your customers do not live in photo studios. - Check color fidelity: if the rendered shade does not match the product photo, trust dies fast. - One-tap launch on the product page. A try-on that needs an app download loses most shoppers before it starts. - Measure it: try-on's real wins, fewer wrong-shade returns and bigger baskets, only show up in the data. ModelSnap produces the 3D model and AR preview file, $4.99 per HD model.
