Social Augmented Reality Mobile Location-based Service “Sekai Camera” (World Camera)

Their client-side software and web service enable camera-equipped mobile devices (such as iPhones, Android “Google Phones”, and other smart-phones) to access informational and entertainment services by creating a “Clickable World” via the use of Augmented Reality (AR) hyper-tags.

These user-clickable tags, which they call “AirTags”, are location-based and mapped in the real world. These AirTags can be seen and accessed through the camera view of mobile devices with Sekai Camera software.

Sekai Camera is realized though a combination of technologies, including client-side software deployed on iPhone, Android and other OS platforms, and also highly scalable web computing systems. In addition, Sekai Camera integrates with services provided by mobile carriers, existing data/service providers, and location technology companies, which combined, enable this dynamic location-based information retrieval service.

Sekai Camera is a Social, Augmented Reality application that enables users to communicate by attaching digital post-its to the real world.

By looking through the camera view on your iPhone, you can access information that are relevant to that place and time, shown as an overlay on the real world.

The following are some of the features:

  1. User Generated Content Features

Air Tag: location-based digital post-its that can be text, photos or voice messages. Users can share comments, memories, graffiti, and anything else that comes to mind by leaving Air Tags at that place and moment. Other Sekai Camera users can see them by just by holding an iPhone over that location.

Air Filter: a search filter to find the Air Tags users are looking for. By specifying time, distance and type, users can sort through the many floating Air Tags around the location.

Air Pocket: a bookmark that allows users to view Air Tags even when users are not at the location the Air Tags were posted.

  1. Social Communication Features

Sekai Life: a life-log feature that shows how users and their friends have interacted with Sekai Camera in a timeline display. Users can follow other users, and view their comments and actions.

Air Profile: Air Tags that show users’ registered profiles, which float right above any user’s iPhone for others to see – just like name cards with any messages that you may want to add.

Air Tweet: Tweets that can be viewed as floating Air Tags.
