Display Symbiosis

The below table shows that limits of human visual acuity constrain the amount of information that can be shown on direct view displays of small portable devices. Until flexible displays or portable projection displays for small devices become practical, we will be limited by the size of the device. Though wearable eye mounted displays are already available, they have not been adopted in large numbers due to social concerns. Display symbiosis provides a way to overcome this inherent limitation of mobile devices.

Typical resolution of displays and maximum possible resolution according to limitations on human visual acuity, using 20/20 human visual acuity.

Personal devices can also offer a private display. The private display can be used to show personalized information such as a special frequent visitor price that is offered to the user while watching a commercial on a public display such as a television on a train. Another example is one where speaker notes are shown on the small private display while a presentation is being shown on a large screen. Close captions for movies and television shows is another example.
