This particular example may not jive with everyone, but it is possibly a view into the future of using a mobile touch-controlled device to control larger applications and screen displays. In this example, use your iPhone or iPod to control another (desktop) application/screen display in real-time. What if we built an app or outdoor display, kiosk, etc… that enabled users to use their own iPod to control sound, images, outdoor lights, beam music, etc or interact in real-time in some way? Often, when I am walking to work all the way from BART on Market St, listening to my iPod, I feel the desire to use it to control the traffic lights or at least the billboard displays I see on my way.

Finally, Google listened to my prayers! In case you didn’t hear about this yet:

Using the technology, dubbed “My Location,” simply requires pressing zero on a mobile handset equipped with the new software. The sender’s location shows up as a blue dot on Google’s mobile maps.”

** Note that this is not Wi-Fi triangulation; and is not perfectly accurate. But there is so much cool stuff that can be done with this.

1. Location specific content: if you know (roughly) where the person, serve them location-relevant content.

2. Mash-ups with Google maps and our own apps: for example, currently I am prototyping an app that allows a person to send invitations from his/her mobile phone out to his friends. (Invitation automatically include directions for the friend to find the sender). The starting address references the user’s address in a database and then uses Google maps to send out specific directions. However, with this stuff, I wouldn’t need the “hard coded” database profile; it could just access the map location dynamically.

3. Reality Games (Off-the-web games using mobile device) Track where users are in real time.
