A System and Method to Utilize Quad Mode Screens on Pervasive Devices

Device partitioning with current smart phones has many disadvantages. If the smart phones are partitioned on one device, then the unique customization is not possible. It is not possible to have a controlled security level; a user can either set the security level as high or low, but not both. Device resources are shared (e.g., central processing unit (CPU), memory, and storage), which prevents the best performance. Finally, only one view is possible, not both, because the Liquid Crystal Display (LCD) is singular.

The novel contribution is a system and method to utilize dual screens on a pervasive device to enhance usability. The screens can be configured in four distinct modes including an integrated mode such that both smaller screens can be used together as one large screen. The system and method enable the pervasive device to automatically reconfigure the screens based on orientation of the device (e.g., up, down, flat, open, closed), location of the user's fingers (device is 'cupped', 'held' or other carrying position), current application, or profile in use.

The core idea is to have one single smart phone that can be divided into two separate devices. The design allows the user to operate the smart phone in Quad mode, eliminating the need to carry multiple devices dedicated to specific uses (e.g., personal, business, child use, etc.) These uses are established as presets. The design is for a smart phone with a front and back LCD screen. The screens open side-by-side, with a hinge in the middle, somewhat in the fashion of opening a book. The system utilizes a simple switch to determine whether the pervasive device is open or closed. The user has two separate displays that are automatically partitioned to run in Quad mode. The Quads are as follows:


1. Single Device Mode (Flip side B to use side A) (Figure 1)


2. Dual Device Mode (Figure 2)

3. Single Device Mode (Flip side A to use side B) (Figure 3)


4. Single Device with full display (Figure 4)

Further, a profile is configured in the pervasive device to determine what and how the device should be configured in relation to each of the Quads. Perhaps, business contacts and phone logs are configured for side A and personal contacts and phone logs for side B. The combined screen may be configured to act as a union of the two in more of a 'tablet' mode. This profile can be easily configured with presets for the most likely settings.

Figure 1 shows the example of the pervasive device being CLOSED, with side A facing the user. In this configuration, LCD side A is visible. LCD side B is not. The device is then configured to utilize side A's LCD screen only. Based on the profile, this configuration may show a business profile; calls, logs, applications, etc. may be tailored for business use.
