Angle Mouse v2.0.3
Angle Mouse v2.0.3 The Angle Mouse is a pointing facilitation technique that runs quietly in the background and improves the efficiency and ease of mouse pointing, especially for people with motor impairments. The Angle Mouse is a target-agnostic pointing facilitation technique that works by continually adjusting the control-display (C-D) gain based on how coherent (straight) or divergent (angular) the mouse movement is. When the mouse moves straight, the gain is kept high, but when the mouse corrects abruptly, often near targets, the gain is dropped, making targets bigger in motor-space.

OpenDyslexic2 OpenDyslexic is a new open sourced font created to increase readability for readers with dyslexia. From the author, Abbie Gonzalez: "The typeface includes regular, bold, italic, and bold-italic styles, and 2 typefaces: OpenDyslexic, and OpenDyslexic-Alta. It was created to help with my reading, and is being updated continually and improved based on input from other dyslexic users. There are no restrictions on using OpenDyslexic. OpenDyslexic is created to help with some of the symptoms of dyslexia. Letters have heavy weighted bottoms to indicate direction. You are able to quickly figure out which part of the letter is down which aids in recognizing the correct letter, and sometimes helps to keep your brain from rotating them around. Consistently weighted bottoms can also help reinforce the line of text. The unique shapes of each letter can help prevent confusion through flipping and swapping." OpenDyslexic uses unique letter shapes, to help prevent confusion. A heavier bottom is used to show which way is supposed to be down. OpenDyslexic also has other features, like wider letter spacing and a unique italic style. Like how this page looks? The scripts and CSS are available on github, free! OpenDyslexic Mono is included for programming, or other areas where a fixed width font is preferred. OpenDyslexic 3 is now available in Regular and Bold! OpenDyslexic 3 is a ground-up redesign of OpenDyslexic, taking into account recommendations from educators, teachers, and other users. It is released under the SIL-OFL license. OpenDyslexic is free to use: The newest version of OpenDyslexic now uses the SIL-OFL license, giving you freedom to use it for personal use, business use, education, commercial, books, ebook readers, applications, websites, and any other project or purpose you need. This download is for OpenDyslexic2 (Windows, MacOS, Linux OTF). If you need OpenDyslexic2 Alt-A (Windows, MacOS, Linux OTF), download here. If you ...

OptiKey v2.23.0
OptiKey v2.23.0 OptiKey is an assistive on-screen keyboard which runs on Windows. It is designed to be used with a low cost eye-tracking device to bring keyboard control, mouse control and speech to people with motor and speech limitations, such as people living with Amyotrophic Lateral Sclerosis (ALS) / Motor Neuron Disease (MND). OptiKey was written to challenge the outrageously expensive, unreliable and difficult to use AAC (alternative and augmentative communication) products on the market. It is, therefore, fully open-source and free. Forever. It works out of the box once you have your eye-tracking device installed and allows selections to be made using dwell selection, as well as physical buttons and assistive devices (such as Glassouse, or assistive switches). If you do not have an eye tracking device you can use OptiKey with a mouse or your webcam. OptiKey can be used as an alternative to a physical keyboard, allowing you to type into any application. OptiKey can automatically insert spaces between words and capitalise letters for you to increase your typing rate. You can even type whole words and phrases in a single selection by "swiping" or using "auto-complete". OptiKey can replace your mouse, allowing you to click, scroll and drag with precision anywhere on screen. To communicate naturally with those around you select the 'Speak' key and OptiKey will convert what you have typed into speech...even if you find it difficult to select keys... If you find OptiKey useful please consider sponsoring this project: Get started instructions here Changes: v2.23.0 New: Georgian - full support including simplified keyboard Adds new fonts, chosen for their readability: Mandatory (all capitals font, used on UK car registration plates), 'B612' and 'B612 Mono' (used in international air traffic control systems) Fixed: Handling for dynamic keyboards which attempt to use more the 95% of ...

Pointing Magnifier 3 v3.2.2
Pointing Magnifier 3 v3.2.2 A free cursor replacement designed to reduce the need for fine motor control. Created by: Jacob O. Wobbrock, Ph.D. Leah Findlater, Ph.D. Alexis Hiniker, Ph.D. Alex Jansen University of Washington It is also useful in getting a close look at any region of the screen without losing the surrounding context, which has been useful to graphic designers and people with low vision. With the Pointing Magnifier, the usual mouse cursor is replaced by a semi-transparent circular "area cursor." When the user clicks, the area beneath this circular cursor becomes magnified, as if a lens. Once magnified, the typical mouse cursor arrow appears within the magnified lens, allowing for normal mouse operations, but now on much larger targets. The Pointing Magnifier supports all button-based actions: clicking, double-clicking, right-clicking, dragging, and button dwelling, both on the cursor itself and within its magnified lens. It does not trigger mouse movement-based events—mouse over, mouse hover, mouse enter, or mouse leave—due to technical limitations. In version 3 of the Pointing Magnifier, the lens itself can be dragged. It can also be nudged with the arrow keys. In addition, it contains support for multi-monitor displays. The original Pointing Magnifier was developed in 2010-2011 by Alex Jansen, with lead designer Leah Findlater and supervised by Jacob O. Wobbrock. More than a decade later, numerous feature requests and design improvements have resulted in the creation of the Pointing Magnifier 3 by Jacob O. Wobbrock, with help from Alexis Hiniker. As of version 2, the Pointing Magnifier is a complete rebuild containing no code from version 1. See what's new. Comparison to Windows Magnifier How does the Pointing Magnifier compare to the built-in Windows Magnifier? Windows Magnifier has three modes: lens, docked, and full screen. All three are primarily directed towards people with low vision, as they each make some or all of the screen larger. ...

Sim Daltonism for Mac v2.0.3
Sim Daltonism for Mac v2.0.3 A window to color blindness. From the perspective of a color blind person, some colors are impossible to distinguish. Sim Daltonism lets you visualize colors as they are perceived with various types of color blindness. Move the Sim Daltonism window over something on the screen and see what it looks like with a color blindness. With this app you can check the accessibility of websites and other user interfaces, make your visual designs better for color blind people, or just play around to better understand how various color blindness types affect color perception. The Filter Window The Sim Daltonism window acts as a filter for what is under it. You can click inside and manipulate windows from other apps that are located under it. But you can change this so the filter window follows the mouse pointer, displaying the area around it. This makes it possible to view the filtered image alonside the unfiltered one. Performance Sim Daltonism is fast enough to filter a video in real time or to have many filter windows active simultanously. If needed, you can reduce or increase the refresh speed to save energy or improve responsiveness. Simulated Vision Sim Daltonism can simulate the vision of many forms of color blindness: Red-Green Deuteranopia (no green cones) Deuteranomaly (anomalous green cones) Protanopia (no red cones) Protanomaly (anomalous red cones) Blue-Yellow Tritanopia (no blue cones) Tritanomaly (anomalous blue cones) All colors Monochromacy Partial monochromacy Note that the colors ...
