TuneWiki plays audio and video while displaying synchronized lyrics or translated lyrics. It allows for a music based Social Network where users share music information with friends and can sync and translate lyrics directly from their phone. TuneWiki displays music maps that show songs playing in the same GPS location and can navigate the map to any other location in the world to see what’s playing there. It also creates music charts that shows top songs in GPS location, or of any country or state. TuneWiki allows connectivity to Open-Social where users can share what they are playing in real time and allow friends to send feedback to the handset.

The music and video playback abilities for content found on the phone storage and Android’s “Always on” internet connected platform empowered a creation of a virtual library. The music and video can be local or “in the cloud” and play normally, it can be part of any play-list or ad-hoc, played from maps, charts, or recommendation.

GPS powered the localization reporting of music consumption. The Native Google Map shows what plays where and by whom, and the native YouTube player allows the virtual library (any music that played anywhere by anyone) to be shared via the maps and the community.

On the WebApp side, Google generously allowed us to hook their translation engine to translate lyrics on the fly. OpenSocial allows sharing across multiple social networks. Google Map allows sharing with Android-less friends.

With Softrace people around the world meet online to compete against each other in different physical activities. Races can take place in real time, just like traditional races. In addition, races may be constructed from already completed races allowing users to select their opponents and race on demand. Location varies, some races run along predefined tracks while others allow you to run anywhere in the world, in any direction. It is like a computer game, except that you are not controlling the player, you are the player.

Android’s Location API is a necessary feature to sample the user’s location at a certain frequency. The data is used to figure out how far the user has moved since the race started, making it possible to calculate his or her position in the race.

The Maps API allows users to see where they are or where they are going during the race. The Maps API is also used when races are revisited in the Diary.

The Softrace Stats feature is taking advantage of Android’s SQLite database where completed races are stored. The database is queried to reveal interesting statistics about the user’s performance.

Locale allows you to create Situations, which specify Conditions under which your Settings should change. For example, your At Work situation might notice when your location condition is 1600 Amphitheatre Parkway, and triggers your ringer volume setting to vibrate. Locale is an innovative way to simplify your life.

Locale allows users to manage and create locations using an intuitive interface based on the Maps API. Locations can be moved and re-sized using a touch-based drag and drop interface. Locations may be used to specify conditions and may also be reused by other applications.

Users specify locations, times, and other conditions to trigger on. Location conditions utilize Android’s location API for high precision GPS positioning. Conditions may also communicate with other parts of Android via Intents and ContentProviders for a highly integrated system.

Users also specify which settings to change once conditions are met. Utilizing the open nature of Android, Locale is able to control all the standard settings available. Further, Locale is highly extensible by supporting third party settings plug-ins.
