Overview
Mechanisms are provided for identifying, selecting, presenting travel media to users of a mobile device. User location information and directional information is received and travel media including images, video, and audio relevant to an attraction within visual range of a user is presented. A user turning toward a particular monument may be presented with an audio or video tour of the monument that progresses as the user moves about the monument. A user approaching a particular district may be presented with video commercials about fine dining in the area. Presentations may be adjusted as the user changes location or changes viewing direction and selections may be tailored to user interests and preferences.
Particular Embodiments
Travel related information can be presented in a variety of manners. Travel guides and shows present depictions and information about various destinations. Travel advertisements promote attractions. Hotels provide pamphlets and channels dedicated to providing visitors with information about local destinations and attractions. Concierge personnel advise guests on places and services. In many instances, guides will verbally describe various sites as travelers tour attractions. Museum docents provide detailed information to visitors about pieces in a particular exhibit. Automated audio streams may also be provided as visitors enter particular numbers corresponding to particular pieces in a museum. As a visitor moves from one piece to another, the visitor enters a numeric sequence to hear an audio description of the piece on a headset and audio playback device.
However, mechanisms for presenting travel media are limited. In many instances, conventional mechanisms lack not only location awareness, but directional awareness and do not provide a rich media experience. Furthermore, travel media can not be personalized based on a user's individual preferences, interests, listening style, etc. Conventional travel media also have limited flexibility and content. Consequently, the techniques and mechanisms of the present invention provide travel media in a personalized, locationally aware, and directionally aware manner. A user walking past a particular monument on the left may be presented with information about the monument. As the user turns and faces a different direction, a different video or audio sequence may fade in to describe a different structure that corresponds to the direction that user is now facing. In some instances, the information may be a locationally and directionally triggered video or audio tour of a museum. A mobile device may use cell tower triangulation, a global positioning system (GPS), radio frequency identification (RFID), Wi-Fi tracking, magnetism, motion detectors, gyroscopes, laser sight tracking, etc., to determine location, movement, and direction.
According to various embodiments, a system identifies user preferences and describes attractions and destinations in a manner that corresponds to user preferences. In particular embodiments, the user may be particularly interested in historical aspects of an attraction and a historical presentation may be provided to the user when a user approaches an attraction. In other embodiments, the user may be particularly interested in biographies of artists of works in an exhibit as opposed to the pieces of art themselves. Travel media preferences may be used to select media streams of particular genres for presentation to a user. In other examples, travel media preferences include not only historical, biographical, scientific, etc., but also include attraction types such as seafood restaurants or scenic points.
When a user drives or walks in the area of a seafood restaurant, a presentation or advertisement for the seafood restaurant may be viewed on a mobile device. Mobile device video and audio tours of museums, monuments, natural wonders, structures, districts, attractions, shopping areas, etc., can personalized, location aware, directionally aware, etc. In particular embodiments, a user moving to a particular location or facing a particular direction at a particular location automatically triggers presentation of a video or audio stream relevant to the location and direction. A user may set a personalized guided tour that directs a user to travel along a particular route where the user can stop at attractions of interest while a mobile device presents video or audio data associated with the attractions of interest.
