Wrist watches using this method have been on the market for many years. Seiko is but one example of such.

Now the second step would be to licence this patent to all other handset manufactures in the world for free, EXCEPT APPLE.

Could even start a consortium called HAAA (Handset Alliance Against Apple), which Nokia, HTC, Motorola, Google, and so on could use to share technology and protect each other against the aggressive, anti-competitive attacks of Jobs and his fruit-themed Fourth Reich.

(would not recommend that Microsoft be allowed to join the "HAAA club", as they tend to embrace, extend, and extinguish their "business partners").
