Abstract
A system provides a recommendation of food items to a user based on nutritional preferences of the user, using a head-mounted display device (HMDD) worn by the user. In a store, a forward-facing camera of the HMDD captures an image of a food item. The food item can be identified by the image, such as based on packaging of the food item. Nutritional parameters of the food item are compared to nutritional preferences of the user to determine whether the food item is recommended. The HMDD displays an augmented reality image to the user indicating whether the food item is recommended. If the food item is not recommended, a substitute food item can be identified. The nutritional preferences can indicate food allergies, preferences for low calorie foods and so forth. In a restaurant, the HMDD can recommend menu selections for a user.
