Disclosed are various embodiments for implementing a zooming application that pairs an optical head mounted display (OHMD) device with an electroencephalogram (EEG) sensor to facilitate the control and the level of magnification as well as the text-to-speech conversion of any text depicted on an optical head mounted display device. The zooming application may be configured to perform various operations such as, for example, zoom-in, zoom-out, text-to-speech, freeze, and/or other operations on an image as well as text depicted on an optical head mounted display device in response to a triggering signal obtained from the electroencephalogram (EEG) sensor, motion detecting sensor, neural implant, or other sensor.
