"Sight Search" allows users to choose items by staring at them for a few seconds. Staring at the "Add to Basket" button also adds items to the cart, but users have to pay for their purchases manually. Steve Brennen, eBay's senior director of marketing and retail innovation, told Mashable Australia: "Your eyes can move so quickly... Sight Search in a VR world of retail feels very sensible. How much customers use it, do they love it, is where we'll get to next." We're guessing the company plans to improve Sight Search even further, perhaps to allow users to pay with their eyes, as well. Since not all of us can access the app, you can check out a short demo in the video below.
