Apple knows how hard it can be sometimes to use your iPhone when moving around, such as when jogging or bustling to your next appointment.

According to a new Apple U.S. patent filing, the company is developing technology that will help improve touch accuracy by making OS elements larger depending on motion-based activity.

The software will be able to detect “signatures of motion” and then change OS elements accordingly. For example, if you sitting at your desk, it is easy to scroll through your contact list, but the process becomes a bit cumbersome if your jogging with the smaller font and list. The new technology will detect motions and enlarge that list accordingly, as seen above from the patent filing.

Other elements of the OS will also change accordingly, including text, icons, among other elements.

This technology is still a while away, if it will ever materialize to begin with.

According to a new patent filing, Apple seems to want to re-introduce its digital video answering machine with new features.

The app would let you record videos and send them via iChat to your friends who can view them later. The app would also let you auto-reply with your video to incoming callers if you changed your status to Away or Idle after a pre-specified time.

Going further this time, Apple explained in the filing that the videos could be uploaded on its servers, allowing the video to be displayed even when you are not logged into iChat.

Additionally, you would also be able to respond with your own video audio reply.

The concept was first introduced in Mac OS X 10.5 pre-release version in 2006 but never really materialized.
