Defining Augmentedness – What is mobile AR Part I The Camera
Grab yourself a cup of coffee and help me solve the riddle of how much augmentedness is required to make a mobile application an augmented reality application.
At ARE2010 in just a few weeks I am talking about trends in mobile augmented reality. As part of my research I have looked at every single augmented reality application in the appstore and Nitin has compiled a list of every Android application. That’s around 700 applications that claim to be augmented reality applications.
As part of the research we have compiled a list of all the applications and recorded what the application does, what category it fits into, normalized all the categories (Layar is listed as reference, Wikitude is travel), and attempted to list why it classes itself as an augmented reality application. Now I have my huge list of applications it’s led me to ask the question, just what is mobile augmented reality anyway.
If I said I saw a great augmented reality demo, chances are the first thing that comes to mind is someone waving a marker around in front of their webcam. If I said I saw a great mobile augmented reality demo you’d probably think of waving a phone around to see nearby points of interest. There are however applications with various levels of augmentedness, so as part of my analysis, I separated every application into categories on how they claimed to be AR,.
I categorised applications into 5 categories.
- Camera display
- Image recognition
- Location aware
Over the next few posts, we’ll look at these categories of augmented reality and between us we’ll decide what level of augmentedness we expect before an application can call itself an augmented reality application. Today we’ll start with the camera display.
Camera display – The application turns on the camera to overlay content in the camera view.
Applications that fall into this category typically come from several groups of applications.
- World browsers (Wikitude, Layar, Junaio, Tagwhat etc)
- Games (Pandemica, Arcade Reality etc)
- Image manipulation (Zombie Cam, Holiday Cam, iLiving etc)
- On screen see through (Type’n walk, Tweet Through etc)
World browsers, personally I am happy to call these applications augmented reality applications, I realise that they have their detractors who claim that the camera serves no purpose, and if you place your finger in front of the camera lens the application still works as the application isn’t aware of its surroundings.
I think that’s precisely why world browsers such as Layar and Wikitude are augmented reality applications, if you place your finger in front of the lens they still work but they lose all context without the camera. No camera and the application becomes useless.
If then context is a requirement of augmentedness then how do we classify games such as Pandemica and Arcade Reality? Both are excellent examples of games that use the camera and accelerometer so the action takes place in the user’s surroundings, but here the camera serves no purpose. If I place my finger on the camera the game still plays and it still has its context as the background severed up via the camera serves no purpose.
Above the images are of Arcade Reality showing my messy office, the game is obviously more enjoyable to play than a blank background, even if the camera view adds no context to the game.
Image manipulation appears to be a popular category and in my view the most contentious. Typical examples of these applications include, taking pictures of your friends and adding 3D graphics to the photo. In once sense you are augmenting reality by adding content to the photo and it’s no different to a desktop application that lets you try on sunglasses, clothes, or place a sofa in your living room. But some applications do little more than add a picture frame to the picture, is that really augmented reality?
What is the difference between adding a pair of sunglasses to a face or adding a simple picture frame around a users photo?
On screen see through applications simply turn on the camera and enable you to write tweets, email or texts while walking with your input superimposed on the camera feed, or even divide up a pizza. These applications tick the box of visually showing the camera view and providing a level of interaction with the application, but do they tick your augmentedness box?.
So the questions relating to applications that rely on the camera to display data to the user:
Are all the examples above valid examples of AR?
Is there a quantifiable augmentedness that can be applied?
I welcome your comments.
