State-of-the-art analysis

After reading about ”air based gestures” in the book i realised this technique has been used for a long time. I remember when I was little and had gotten the coolest video game ever, the EyeToy. A game where you play by using gestures. I got to polish windows, catching falling things, jump over obstacles and so on. How cool is that? 

I am thinking that this technique could be interesting for us to apply to an environment with lots of people. Though probably it will be to intimidating for some to be playing a game like EyeToy surrounded by strangers it could instead be used as a way for people to easily get desired information. Or if we want to go with the entertaining approach maybe this is more suitable for children and can be a good way of keeping them focused and not wandering away from their parents or kindergarden teachers . 

I found this video showing how this technique has been applied to a Galaxy S4, and if we would like to use this in a more informative way this could be an example of how it could work.(So sorry for a cheesy and very commercial video, but just want to show you an example of how to use the technique in another way). 

This could then be applied to bigger screens placed on platforms/bus stations or maybe even on the transportations. 

As was also mentioned in the book a problem with this kind of technique is to get the device to understand what is a movement and what is not. When does it begin and end. 

Some other troubles that might occur for us is that it can be hard for the device to decide who is making a gesture if several people are moving at the same time. It might also be hard for the user to understand how it works and to have the time to use it. 

I think it is interesting to have all this in mind later on when we figure out what problem we want to solve. Maybe this technique will be perfect or maybe it wont be applicable at all. 

The future will tell.
