Description of Telescopic Low Vision Aids with Motorized and Auto Focuses



Abstract: Prototypes of motorized-focus telescopes (MFTs) and of a 4X auto-focus telescope (AFT) were constructed, and 22 users of hand-focus telescopes (HFTs) were trained to use them for near-distance and intermediate-distance tasks. Despite the lack of differences in performance with the MFT, AFT, and HFT, the subjects' ratings on 9 of 10 aspects of telescope performance were significantly higher for the AFT and MFT than for the HFT.
