Abstract: A wearable device can include an inward-facing imaging system configured to acquire images of a user's periocular region. The wearable device can determine a relative position between the wearable device and the user's face based on the images acquired by the inward-facing imaging system. The relative position may be used to determine whether the user is wearing the wearable device, whether the wearable device fits the user, or whether an adjustment to a rendering location of virtual object should be made to compensate for a deviation of the wearable device from its normal resting position.

Abstract: Disclosed herein is an augmented reality (AR) system that provides information about purchasing alternatives to a user who is about to purchase an item or product (e.g., a target product) in a physical retail location. In some variations, offers to purchase the product and/or an alternative product are provided by the merchant and/or competitors via the AR system. An offer negotiation server (ONS) aggregates offer data provided various external parties (EPs) and displays these offers to the user as the user is considering the purchase of a target product. In some variations, an AR system may be configured to facilitate the process of purchasing items at a retail location.
