Controlling Your Linux System with a Smartphone
The most-used application I have built is a television remote control. We use the fantastic tvtime program to watch all our TV. The tvtime package includes the tvtime-command command that allows you to control every conceivable function of the running tvtime instance. For example, tvtime-command chan-up changes the channel up one increment. Full documentation can be found in the tvtime man page.
I used all the same techniques described earlier and built a full functioning remote shown in Figure 4.
Now friends and family can control the TV from the comfort of their very own smartphones. There are no more complaints about using our giant Bluetooth keyboard as a remote either. The kids simply can grab the closest iPod Touch, Palm Pre or whatever.
Smartphone technology is advancing extremely rapidly. Without modifying the phone, you can access almost any possible function on a remote computer through the built-in browser. Linux users are especially lucky. It doesn't take much effort to turn a Linux computer into a back end for a phone. Hopefully, this article inspires you to come up with your own unique and interesting uses.
