Our study showed that a good number of the older generation are not so effective at the use of computers, but when it comes to mobile phone use, they are almost at par with the younger generation. Most of the apps and interventions we're going to be designing are going to be running on phones. They can be used by anybody, older people and younger people alike. That's why we feel that applications for mobile phones are the in thing. They are the way forward, because mobile phones go with people wherever they go. They're something anybody can use.
The key here is that you don't have to learn it and you don't need to buy anything extra. You just have it with you. When something extra needs to be attached to the cellphone or the person, it adds another difficulty to the behaviour you want to promote. However, if I'm able to get it into the phone you're already using, then if you know how to dial a number, you can use the application. We're actually targeting the whole group, both the old and young generations.
That's why I said that mobile phones are going to be the future. They're going to be the in thing that everybody can use. You don't need any extra thing. You don't need to learn. There's almost zero learning curve involved.
