Sonar - Project Draft
Contents
Definition
FreeSonar is a mobile free software for real-time location-based socializing, sharing PoI, self-organizing and sharing events, travelling, ride sharing and other features.
FreeSonar helps to link the virtual world of social network users into real world around them, encourageing to interact in real time at real places based on shared interests or shared activities.
FreeSonar is designed to be interoperable with other similar open services and applications carefully considers users freedom, privacy and security providing them maximal control of their visibility, ownership of their personal data and independence from proprietary services.
Description
Sonar provides new and efficient ways for socializing, organizing events and travelling. Using their mobile phones or desktop PCs users can:
- find each other based on their location and interests and securely communicate with each other using the P2P social networking/microblogging features.
- share real-time information about their current activity and location, organize new events, look for real-time events around them, or publish a demand for a specific type of event for the specific area.
- share their ongoing or future travel plans. If they are driving a car and willing to share available free seats the Sonar can assist them in real time to find people moving the same way (similarly the Sonar can assist hitch-hikers to find a ride).
Features
Simple user interface
- Almost invisible user interface, intuitive, minimalistic.
- Visualization of the geo-radar.
Social networking/microblogging
- Decentralized authentication.
- Personal profiles.
- Friends list/groups.
- Private messaging.
- Wall posts, microblogs.
- Profile search by name/location/keyword/etc.
Event/activity sharing
- Organize events or activities: party, training, exhibition, festival, etc.
- Publish event demands.
- Join/subscribe to public events.
- Search events by title/keyword/status/location/time.
- etc.
Travel/transport sharing
- let hitch-hikers know that there are available car sits from location A to B (real-time or at the specified date).
- let drivers know that you need to go from location A to B (real-time or at the specified date).
- share travel plans.
- share travel experiences, read/publish into geocoded wiki articles. The Wikitravel project is of special interest:
- Wikitravel - Wikitravel is a project to create a free, complete, up-to-date, and reliable worldwide travel guide. So far it has 24,445 destination guides and other articles written and edited by Wikitravellers from around the globe.
Location sharing, real-time map and AR objects
- Display current location on a map (if enabled by user's privacy options).
- Publish/search places of interest: coffee houses, hotels, accommodation rentals, etc.
- Publish geonotes: users can leave a note at a specific location for themselves or other people which they will receive next time being there.
- Manual user checkins into the places and defined areas on the map.
Location triggers
- Automatic location trigger to check-in the user into user's predefined list of areas/places.
- Automatic triggering of a specified callback URL when user enters or leaves a specific location.
- Automatic check-ins on other geo-social platforms using open APIs (Foursquare, Facebook Places, Latitude, etc).
Radar with alerts/proximity notifications
To eliminate the necessity to query for a specific real-time object repeatedly users can place alerts or subscribe to proximity notifications for the following:
- If there are people matching specific search criteria in near proximity.
- If there are places-of-interest matching the given search keyword/tag.
- If there is a car with free space/hitch-hiker going to a given destination.
- If there are other travel plans match the given destinations/activities/interests.
- If there are non-private events matching the given keywords/tags/dates/location/status/etc.
Open APIs
- Provide open access APIs and web services.
Architecture
P2P social network platform
There are already several protocols and free software implementations for federated/decentralized/P2P social networking and micro-blogging platforms and Sonar intends to integrate the existing best practises.
But there no solutions yet for having distributed/P2P real-time maps and location sharing services without the use of centralized web services. So for the current stage project Sonar will have to provide some non distributable central web services as well.
Real-time geo-map
Sonar has to provide real-time map of:
User locations: GPS-enabled mobile phones which are connected to the internet will send data to the server at regular intervals. If there is no GPS the location data can be calculated from wifi spots and cell towers with sufficient approximation.
Event locations: events happening at a specified time span at a specified location.
Places-of-interest: places named by users not as street addresses but locations like "Home", "Dood's Club" etc.
Augmented reality layers
Sonar has to provide map layers of AR objects, and aggregate other 3-th party AR layers into the map (Google Maps and Layar provide web services and open APIs to access their user contributed database of places-of-interest on different layers).
Promotion Plan
- Build testbeds to demonstrate the software on one or more usage areas.
- For the start find one specific niche, a community and offer the new networking opportunity to them creating their unique social graph.
- Offer collaboration to mobile operator companies. If possible use the contact list of user's mobile phone, identify the numbers via the mobile service provider and use the social graph of the mobile users as a kick-start for our social network.
- Offer solutions to universities and start networking the students.
Evaluation
The growth and potential of the mobile market is really amazing. A new report from Juniper Research says that the number of subscribers using mobile Internet services will rise from 577 million currently, to top 1.7 billion by 2013, spurred by demand for collaborative applications known collectively as 'web 2.0,' and greater 2.5/3G penetration. Putting that figure into some context, a report from Gartner earlier this week had said that the worldwide PC base would reach 2 billion by 2014 - so internet access by mobile phones will represent at around 50% of the total internet usage.
