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.

Abstract: Technology is described for controlling a virtual object displayed by a near-eye, augmented reality display with a real controller device. User input data is received from a real controller device requesting an action to be performed by the virtual object. A user perspective of the virtual object being displayed by the near-eye, augmented reality display is determined. The user input data requesting the action to be performed by the virtual object is applied based on the user perspective, and the action is displayed from the user perspective. The virtual object to be controlled by the real controller device may be identified based on user input data which may be from a natural user interface (NUI). A user selected force feedback object may also be identified, and the identification may also be based on NUI input data.

Abstract: A system for generating and updating a 3D model of a structure as the structure is being constructed or modified is described. The structure may comprise a building or non-building structure such as a bridge, parking garage, or roller coaster. The 3D model may include virtual objects depicting physical components or other construction elements of the structure. Each construction element may be associated with physical location information that may be analyzed over time in order to detect movement of the construction element and to predict when movement of the construction element may cause a code or regulation to be violated. In some cases, a see-through HMD may be utilized by a construction worker while constructing or modifying a structure in order to verify that the placement of a construction element complies with various building codes or regulations in real-time.

Abstract: Methods for generating and displaying people-triggered holographic reminders are described. In some embodiments, a head-mounted display device (HMD) generates and displays an augmented reality environment to an end user of the HMD in which reminders associated with a particular person may be displayed if the particular person is within a field of view of the HMD or if the particular person is within a particular distance of the HMD. The particular person may be identified individually or identified as belonging to a particular group (e.g., a member of a group with a particular job title such as programmer or administrator). In some cases, a completion of a reminder may be automatically detected by applying speech recognition techniques (e.g., to identify key words, phrases, or names) to captured audio of a conversation occurring between the end user and the particular person.

Abstract: Dynamic role selection of players for different roles in multiplayer gaming sessions is provided. Users seeking to participate in different roles in the game may request participation in the role. Selection of players for roles is made dynamically by varying a selection component for different sessions of the game. The selection component may be a user's game score over different time periods, and can be rotated for different sessions of the game, so that various levels of players have an opportunity to fill game roles.
