Abstract

A method of enhancing a visual image of a display is described. The visual image is displayed on a first display of a display device having a first display pixel density and a first display dimension. The display device detects an enhancer device oriented in an operable position to the display device. The enhancer display device has a second display having a second display pixel density higher than the first display pixel density and a second display dimension less than the first display dimension. A spatial orientation is determined between the first display of the display device with the second display of the enhancer display device. The display device sends the visual image and the spatial orientation to the enhancer display device to display a portion of the visual image that is defined by the spatial orientation on the second display in the second display pixel density.

Claims

1. An enhancer display device, comprising:

a physical structure, which acts as a unique signature of the enhancer display device, and is detectable by a first display device, wherein the unique signature identifies to the first display device the enhancer display device and indicates that the enhancer display device is in an operable position relative to the first display device;

a processor; and

a memory communicatively coupled to the processor, wherein the memory is encoded with instructions, and wherein the instructions when executed by the processor include;

receiving, with the enhancer display device, a spatial orientation of a first display of the first display device to a second display of the enhancer display device, when the enhancer display device is in an operable position with the first display device, where the first display has a first display pixel density and a first display dimension, and the second display has a second display pixel density higher than the first display pixel density and a second display dimension less than the first display dimension;

receiving an electronic visual image viewed on the first display;

determining a portion of the electronic visual image to be displayed on the second display of the enhancer display device, the portion is defined by the spatial orientation of the second display to the first display, wherein the portion of the electronic visual image to be displayed corresponds to a portion of the electronic visual image viewed on the first display that is directly overlaid by the enhancer display device;

displaying on the second display of the enhancer display device the portion of the electronic visual image of the first display device determined by the enhancer display device;

detecting an input event made on the enhancer display device; and

sending the input event to the first display device to update the electronic visual image on the first display device as if the input event occurred on the corresponding portion of the electronic visual image on the first display overlaid by the enhancer display device.

2. The enhancer display device of claim 1, wherein the unique signature is made up of contact points having a specific geometric disposition.

3. The enhancer display device of claim 2, wherein the unique signature has four contact points in the geometric disposition of a trapezoid.
