gWalk supports all 3 phases of a touristic experience by helping to plan and explore a tour in advance (Dream), by providing context based support, navigation and multimedia information while executing the tour (Action) and creating an individual diary with snapshots afterward (Memory). The tours can be calculated in advance or on the fly based on the current user-situation and preferences. Additionally, the destination can be discovered freely by a strolling mode. The application can adapt a tour if the original tour plan no longer fits with the current situation (e.g. removing or inserting Points of Interest).

gwalk does a location-based information presentation and context triggered tour-adaption using Android’s location API.

gwalk uses the Maps API to show current position and the next Point of Interest on a map.

Android’s multimedia capabilities are used to display images, play audio-content and take snapshots. The Network API is used to download and pre-load the content to the mobile device.

GolfPlay has been created as an answer to the high demand existing amongst golf lovers for reliable, accurate and free software. Its objective is to give support to all the real time necessities of a golf player during a game. GolfPlay uses GPS location and an online querying site where it is possible to access their personal game statistics as well as a social network to exchange impressions with other users about the sport that links them: golf.

The GPS allows GolfPlay to display where the player is over a Google Maps rotated image using real and 2D visualization of the course.

The Maps API with some additional information about the holes’ location are used to calculate statistics (distance, number of shots, score and hole data calculations) and display them on Google Charts, which are accessed via the web. These statistics and reports are what makes GolfPlay a useful training tool for players.

Fingerpaint lets you communicate visually, allowing you to show people ideas instead of just describing them. Fingerpaint is fun, useful, and easy to use; draw with others, draw on pictures, maps, websites, or just doodle. Fingerpaint is fun, but it’s more than that too. Because it’s collaborative, it’s an aid to communication, and many things are best expressed visually. There is a reason “show, don’t tell” is oft-repeated for effective communication. A business user could sketch a graph or diagram while on the road, or a kid in a classroom could draw horns on a picture of his teacher with his friends.

Using Android’s built-in map, browser, and camera APIs, you can point out a location on a map, mark up a website, or doodle on a picture.

Fingerpaint has infinite canvas space – so the size of the screen doesn’t determine the size of your drawing. Simply slide the canvas over, or zoom in or out, to give yourself more space. This is all made possible by Android’s advanced 2D drawing APIs.

Because of Android’s built-in database, you never need to think about saving – Fingerpaint saves everything automatically, from the second you put it on screen.

The game combines elements of strategy, role-playing, sports, social and tactical games. The central idea behind the concept is to give people the opportunity to symbolically interfere with the everyday urban environment and come into contact with previously unknown people. By introducing a metaphorical recapture of the city‘s elements (buildings, squares, streets), a virtual reorganization of the urban space leads to a new relationship between the players and their environment. In the sacred space of the game world, the city is under their control thus giving the players a feeling of superiority. They contrast with the institutionalized and organized space and give it spontaneity and dynamics.

In order to create a unique visual experience and to create a feeling of a 3-dimensional virtual space, we chose to use the 3D capabilites of Android. A pure Maps mashup is unsuitable when it comes to creating a game world as it is heavily associated with everyday activities.

Without proper locating technologies the game is unthinkable as the whole gameplay relies on the position of objects and people which need to be shared in real-time, using Android’s GPS.

As the playing field changes continuously, everything relies on updating all players simultaneously, so Android’s always-on connectivity is vital
