Smartphones can be used as magnifying devices to compensate for low visual acuity. However, it can be challenging to pan both vertically and horizontally. To simplify panning we implemented a magnifier where the user moves the finger along the text on the reading surface instead of moving the device. A controlled experiment was conducted to compare finger-based panning with panning by moving the device. The results show that participants performed better with device-based panning and preferred device-based panning compared to surface finger tracking.
