Method and Device for Typing on Mobile Computing Devices

摘要

The present invention relates to a method and a mobile computing device for reliable and fast text entry. The method relies on a virtual keyboard layout that has a multi-touch interaction surface spread out on both the front and rear sides of a handheld computing device. A user-adaptive updating algorithm allows the virtual keyboard layout to adapt to the user's handling of the device.

主权项

1. A method for providing touch input at a handheld computing device, wherein the device is provided with at least one multi-touch sensing means on its front face, and with at least one multi-touch sensing means on its rear face, wherein the method comprises:
providing, at the device, a virtual keyboard layout, which maps at least one first target area of said rear face multi-touch sensing means to a first predetermined input element, and at least one second target area of said front face multi-touch sensing means to a second predetermined input element; detecting, at the device, the location of at least one touch event on said multi-touch sensing means; determining, at the device, a likely target area of said touch event on the virtual keyboard layout; storing, at the device, the detected touch event location and the corresponding determined target area; and updating the virtual keyboard layout, wherein the location or shape of said area is adapted based on the detected touch event location.
