Demonstration devices and methods for enhancement for low vision users and systems improvements

A method of modeling a focus of attention (FOA) for a low-vision user with a head-mounted visual aid device, comprising the steps of:

• capturing real-time video images with a camera of the head-mounted visual aid device;
• sensing at least one movement parameter of the head-mounted visual aid device over a first time period with at least one sensor of the head-mounted visual aid device;
• determining in a processor of the head-mounted visual aid device if the low-vision user is engaged in a scanning behavior;
• if the sensed at least one movement parameter does not exceed a first movement threshold and the low-vision user is engaged in the scanning behavior, activating electronic image stabilization in the head-mounted visual aid device to produce stabilized video images;
• and
• presenting the stabilized video images to the low-vision user on a display of the head-mounted visual aid device.
