Glow is an iPhone app that lets you share your feelings with the world and see how happy the people around you are.
The app uses Google Maps to let you view the happiness levels of those in your neighborhood. Alternatively you can zoom out the map view and see the happiness levels of the whole world. The map includes filters that enables users to view feelings by age and value, or limit the view to show only your feelings.
The app also includes an augmented reality view that allows you to use the camera view on the iPhone as a window on the emotional feelings of your location, superimposing the collected data on your current view.
Two academics at the London School of Economics are carrying out research into how the environment affects people's happiness. To help them gather the data for this research they have launched an iPhone app called mappiness.
If you download the app you will receive a notification between one and five times a day. The notification will ask you to open the app, briefly report how you're feeling and who you're with, where you are, and what you're doing. If you're outdoors and you're happy to, you'll be asked to take a photo of your surroundings as well.
You can also open the app and report on your feelings and situation, unprompted, as often as you like.
Anyone can keep an eye on the research being gathered by checking out the mappiness Google Map. The map shows the outdoor places where mappiness users have most recently reported feeling happy. If you click on an information window you can also view the photograph taken at that happy moment.
If charts and graphs are more your thing you can also check out the happiness meters and a graph of happiness levels charted over the past few days.
World of Emotions
World of Emotions are attempting to map the feelings of the world. To register their emotions users just click on a happy, sad or neutral face and their mood is added to a Google Map of the world.
It is possible to refine the results on the map by different emotions. Users can view the positive, negative or neutral emotions on the map or view results for the last hour, day, week or month. The site also provides a table that ranks the world's countries by their degree of happiness.
