SpotChallenge

SpotChallenge is a playful, social, location-aware mobile application that challenges its users to find places and details in our living environment. Any user can create challenges that are composed of sets of images taken from some recognizable details in our living environment (e.g., some building, logo, public art work) as well as optional related textual and location hints. Images are also used to prove users’ findings by matching the images in the mixed reality overlay mode with the real world counterparts in the camera view of the mobile phone. Matching every image in the challenge with the real world counterpart in the right location makes the challenge passed.

The application consists of server as well as a mobile client including Python module and Symbian modules.
- Server stores and serves the challenge related information (images, textual hints, locations, user details etc.)
- UI is done with Python for S60.
- Image similarity measures are calculated in real time by a Symbian application, called directly from the Python script.
The client implementations were done using Python for S60 1.9.2 and Symbian S60 Series 3. Contact: olli.pihlajamaa@vtt.fi
