Abstract:
1. A computer-implemented method for adjusting print format in an electronic device, the method comprising: receiving content for printing in a first print format by a processor of the electronic device; continuously measuring current distance between a viewer and a display of the electronic device by a distance detecting device of the electronic device; when the current distance between the viewer and the display is equal to a predetermined distance, determining a visual condition of the viewer at the predetermined distance by the processor; determining a second print format based on the first print format and the visual condition of the viewer by the processor; and printing the content in the second print format; wherein the step of determining the visual condition of the viewer comprises: displaying a visual acuity test chart on the display; determining a visual acuity index by testing the viewer using the visual acuity test chart; and determining a minimal size relative to the visual acuity index, wherein the minimal size is a size of which a visual element smaller than is unrecognizable for the viewer at the predetermined distance; the step of determining the second print format comprises obtaining size of the second print format by using an equation as follows: where S 2 represents the size of the second print format, S 1 represents size of the first print format, S va represent the minimal size relative to the visual acuity index, S min represents size of the smallest visual element defined by the first print format.
