Abstract

Over the past 5 years there has been a proliferation of smart phones, and other intelligent devices such as the ipod touch and more recently the iPad. A significant drawback of these devices is limited screen real estate. Many of these devices have virtual keyboards, however being able to hold the device and type at the same time presents a challenge. You need one hand to hold the device and one hand to type, and with tablets that's even more challenging, considering the size and weight of the device. This disclosure proposes a solution to that problem by allowing the user to identify fingers and their position on the rear touch sensitive shell

Identifying finger positions using a touch sensitive shell for keyboard input

Over the past 5 years there has been a proliferation of smart phones, and other intelligent devices such as the ipod touch and more recently the iPad. A significant drawback of these devices is limited screen real estate. Many of these devices have virtual keyboards, however being able to hold the device and type at the same time presents a challenge. You need one hand to hold the device and one hand to type, and with tablets that's even more challenging, considering the size and weight of the device.

This disclosure proposes a solution to that problem by allowing the user to identify fingers and their position on the rear touch sensitive shell

The figure below describes how this device would work:

Each finger can be "seen through" the display


Different fingers are assigned different sizes allowing the user a more natural experience - allowing the user to identify the location of the finger for input.

A user can type by lifting and dropping a finger on the "rear" keyboard or use the style proposed recently by Cliff Kushler, a developer of the T9 text entry system that most of us use on our text messaging called Swype - dragging from one letter to the next to complete the input ( http://www.gadgetell.com/tech/comment/swype-changing-text-messaging-as-we-kno w-it/)
