An exploding aging population is a reality previous generations had little or no experience with – but not so now.
Those of us who “fit” into the aging population paradigm, are increasingly aware that motor skills may not be quite as sharp as they once were. For some, this can be quite noticeable when manipulating a computer pointing device – accuracy may be an issue.
Regular reader Michael F., has passed on his recommendations for two free Mouse applications – one of which (Angle Mouse) has been expressly designed to assist with movement accuracy. The other (Pointing Magnifier), is an assistive application which can be used selectively, to enlarge screen content.
Pointing Magnifier – from the site:
The Pointing Magnifier is a two-stage pointing technique. During the first stage the user controls an area cursor of arbitrary size depending on the pointing accuracy of the user. To interact with a target, the user places the area cursor over that target and activates it by clicking any mouse button. This causes everything under the circular cursor to be magnified, and the cursor is pinned in place.
While magnified, the user controls a standard mouse pointer inside the magnified area. Upon performing an action (e.g., clicking, dragging) in magnified space, the pointer’s location is transposed so that the interaction occurs at the correct position in unmagnified space. After the user performs an action, the Pointing Magnifier returns to its original size and the user resumes control of the area cursor.
Setup is uncomplicated, but I suggest that you consider the available options carefully. You may need to experiment to find your optimal settings.
An awareness of the keyboard shortcuts is important, otherwise you run the risk of a frustrating experience.
Two times magnification illustrated – I found the default (4 x magnification), too large for my needs.
If you, or someone you know, find reading enlarged screen content more comfortable, then this application is worth considering.

Angle Mouse – from the site:
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.
The application is highly configurable, as the following screen capture illustrates.

Captcha Monster Eliminates CAPTCHA Completion Frustration
The CAPTCHA, short for “Completely Automated Public Turing test to tell Computers and Humans Apart”, serves a useful purpose – minimizing, or eliminating, one of the scourges of the Internet; the comment spammer. I can speak to how disruptive comment spam can become since, on a daily basis, I have to deal with 300 – 400 comment spams on this site. It’s infuriating, frankly.
I’ve often though of implementing a CAPTCHA scheme here – but then, I come to my senses. I hate CAPTCHAs and, I do everything I can to avoid sites that use them. I’m just no good at trying to work out a “u” from “v” – an “rn” from an “m”. I could go on but, you see the point, I expect.
I’m hardly alone in this, and as an alternative, many sites off an audio CAPTCHA. You’d think that this would solve the problem for people like me – but no. Generally, I have absolutely no idea what’s been read back. The end result? I’m out of there.

So, is there a solution for people like me who have a low solve percentage? (in my case approaching zero
) As it turns out – there is.
Captcha Monster – “an easy-to-use, innovative Firefox add-on that completes CAPTCHA tests without you even asking it to. The add-on was designed with people who suffer from dyslexia and/or sight problems in mind, but also extends to those who are just plain fed up of having to prove they are not a site-hacking machine.”

Fast facts:
Unlike many Firefox add-ons however – Captcha Monster is not a free service. Instead, the developer offers a number of monthly plans – as follows.
Basic plan – 60 CAPTCHAs a month @ $2.99 monthly.
Extended plan – 120 CAPTCHAs a month @ $4.99 monthly.
Professional plan – 760 CAPTCHAs a month @ $9.99 monthly.
System requirements: Firefox.
Download: You may download a 30 day trial version at the developer’s site: Captcha Monster.

A big shout to Mateusz M. for taking time to turn me on to this service.
