Patent number 8564574 is assigned to
The following quote was obtained by the news editors from the background information supplied by the inventors: "The conventional electronic apparatus are mostly equipped with one or more typical plane input apparatus, such as a keyboard, a hand writing pad, a plane touching panel, or an input apparatus requiring an operational plane, such as a mouse or a trackball. Among the smaller handheld electronic apparatus, however, space is often inadequate for users to operate along with the conventional plane input apparatus as described above. With electronic devices, such as PDA (personal digital assistant) and cellular phones becoming more powerful and more compact, machine-user interface is always a challenge. A conventional solution is to provide touch panels through viewable screen such as touch pads, e-books, or e-papers.
"A problem associated with a conventional plane input device or a typical touch pad is that the user's hand and fingers obscure user's ability to see the screen when the user tries to touch the pad. For example, selecting text using a finger over a portable screen can be cumbersome. Also, human hands are capable of moving in a three-dimensional space, while a conventional human-machine interface device is typically only one-dimensional."
In addition to the background information obtained for this patent, VerticalNews journalists also obtained the inventors' summary information for this patent: "An input apparatus with multi-mode switching function is disclosed. The input apparatus with multi-mode switching function includes a body, an arc surface touching module and a control module. The arc surface touching module is arranged on the surface of the body for inputting a two-dimensional position data. The control module is operable to switch the input mode of the input apparatus based on the two-dimensional position data, and generates a control signal based on switched input mode and the two-dimensional position data. In one embodiment, the control module is further operable to transform the two-dimensional position data into three-dimensional position data based on the geometric characteristics of the body, and switch the input mode of the input apparatus based on three-dimensional position data, and then generate a control signal based on the switched input mode and the three-dimensional position data.
"With these and other objects, advantages, and features of the invention that may become hereinafter apparent, the nature of the invention may be more clearly understood by reference to the detailed description of the invention, the embodiments and to the several drawings herein."
