LetterScroll uses a mouse scroll wheel to move the cursor through the character set (Figure 1). The set can be expanded to include numbers, diacritics, and special symbols such as punctuation. Our character set uses the 26 letters in the EnglishĪlphabet. The underlying concept is the date stamp method where increment and decrement operations maneuver a cursor LetterScroll is a text entry technique that extends an earlier three-key technique to include visually impaired users. (SMS) difficult for visually impaired users. Smallĭevices such as mobile phones rarely include Text-To-Speech and this makes the simple task of sending a text message A key question is, are these electronic devices usable by visually impaired users and, if so, to whatĮxtent? In general, text entry is highly reliant on vision, leaving visually impaired users at a disadvantage. Increasingly, text-based tasks are shifting from physical channels, such as paper, to electronic channels, such as mobile Information Interfaces and Presentation, User Interfaces: Input Devices and Strategies Visually impaired, text entry, auditory feedback, voice synthesis, mouse wheel In a study with sevenīlindfolded participants, entry rates averaged 2.9 wpm for M1 and 4.4 wpm for M4. Method 4 (M4) also uses the keyboard to access vowels. After extensive analyses and pilot testing, two variations were chosen for initial evaluation. Keystrokes per character ( KSPC) vary fromĦ.97 to 2.68. LetterScroll uses a mouse wheel to maneuver aĬursor across a sequence of characters, and a button for character selection.

#SCROLL REVERSER M1 UPDATE#
UPDATE (10 March): Thanks to a user who figured out the technical work, Update 1.8.2 with a fix is now released.Tinwala, H., and MacKenzie, I. If anyone has any technical info on all this or solutions btw, I am all ears. So I am afraid for now the only course of action is to wait and see if Apple makes any further changes to "un-break" it. That means whatever Scroll Reverser does, it can't reverse the momentum part of the scroll, which is giving the annoying "snap back" effect. It seems Safari is ignoring the direction of the scrolling input during the momentum phase of the scroll, and instead deriving it from some other source. The reason you don't see the problem with the other apps is that they don't attempt to reverse smooth scrolling, only discrete scroll wheels.
Unfortunately, Safari on Monterey 12.2 breaks Scroll Reverser's method of reversing smooth scrolling devices - that is, trackpads and the Magic Mouse. However, neither of them can distinguish the Magic Mouse from the Trackpad - that has always been Scroll Reverser's speciality. MOS and UnnaturalScrollWheels are the main alternatives to Scroll Reverser and both are very good apps.
