Wouldn't it be nice if your colleague's phone could SMS its location to you? If you know position and velocity, you know when they'll arrive. The result: the interface disappears. No redundant actions or queries. The same software could turn your lights on as you approach the house. Or automatically "check in" to certain locations for you. Or leave a note for yourself the next time you're at the store.
In the presentation, Geoloqi founder Amber Case will highlight why developers of apps should look at what users want to do now, as well as what users want to do in the future, why social apps should try to mirror real-world relationships, why sharing should be about who you share with as well as how long you're sharing, and why developers should think about how to make apps "ambient" and require less user interaction.
