Universal Access Tips for Mac OS X


Coming to you live from the shadow of the
Big House. It’s IT For You. Tips and tricks on ITS tools, products, services, and
more with your host Jeanne Mackey Hi, I’m Jane Vincent. I’m the Assistive Technology Lead for the University of Michigan. And, I’m here today to talk about Universal Access
Tips for Macintosh OS X. If you’ve seen the presentation about ease of access tips
windows, some of the features we’re going to talk about here that can benefit people with, and for
that matter without disabilities are going to be very similar. The Macintosh has a smaller feature set than Windows
does, but it does have some features that are unique to the Mac that Windows does not have. So, I’m going to start by talking about the universal access control panel. And the first item, we’ll look at that control panel in
just a moment, but the first item on that full panel is a screen reader called Voiceover. On the Windows side you need to at least install a screen reader. With a Macintosh, a screen reader comes built in. So to give you a little idea of how
voice over works, I can use the arrow keys on the voiceover window to move up and down. And, it’s going to speak what I’m doing. I also have the option of being able to show the text so, for people with
some vision who are just getting use to the computer voice, having the simultaneous audio and visual may be very useful in addition for some people with learning disabilities, the simultaneous
audio and visual may be very useful. So what i’m going to do is to
go in to the speech options. Use the right arrow key to, sorry, use the Tab key to move around these options. And without using the mouse at all, because blind individuals are not
able to use a mouse, I can use the arrow keys to choose a different voice. I’m going to choose Vicky. And then hit return [The best way to predict the future is to invent it] [Closing
menu utility categories table row 3 of 10 speech selected.] [Computer Talking] [Default rate stepper] [50 contents selected Default pitch edit text] I can continue to use the Tab key, the Shift
Tab, to move backwards through options. [Computer Talking] [To enter this table, press Control Option Shift and Arrow] And to use the arrow keys to move around and set my preferences. So, I’m going to go ahead and close voice over. [Computer Talking] And I happened to use the mouse to do
that but I wouldn’t need to. And what we’re seeing here is the Universal Access Seeing panel Now the next option on this panel is zoom.
If I turn the zoom functionality on. Should come on…so… it’s giving me the option of having
a small window just like a magnifying glass. Or, I can zoom the entire screen. Now notice that this is somewhat
blurry, we are going to be looking at another zoom option a little later in the presentation that tends to be much clearer. But this is a fairly flexible option if somebody needs either the entire
screen or a portion of the screen at a time magnified. this does provide at least some magnification capability For some people, it’s easier to see white text on a black background
so I can modify the display so that white on black. Unfortunately, it inverts all the colors, which looks rather unpleasant so, if I prefer I can leave it at black and white and instead use gray scale and that
gives me a very nice black on white or white on black. without having some of uglier colors if I’m doing the white on black inversion. I can also modify the contrast if I
need the contrast to be sharpened. I do have a scroll bar that will let
me adjust that to my particular preferences. The next option under Universal Access is hearing. I’ll go back to Seeing and set it back to a standard contrast. Under Hearing, I have two very nice features. One is a that flashes the screen when an alert sounds
occurs. Very often in a computer operating system it will beep to let you know that there is a problem, but
if somebody if deaf, or hard of hearing, they may they may not be able to hear that beep. They
may not know what is going on. So I can have a redundant screen flash, I can click on the
Test the Screen flash, and it flashes the screen for me and that way, if I’m getting a system beep, I have a
redundant visual that lets me know what’s going on. and that way, if I’m getting a system beep, I have a
redundant visual that lets me know what’s going on. I also have the option for somebody who’s hard of hearing and is only using a microphone in one ear and they have a hearing aid in the other ear if their only using one ear for the headphones their
not going to be able to hear stereo sound so I do have a setting that lets me play stereo audio mono and
that way all the sound is going through the single headphone and the individual will not miss any auditory information. The next option that I have is the Keyboard under Universal Access and this has two very useful utilities. One is Stickey Keys and what Stickey Keys does is if you’ve ever had to type using fewer than ten
fingers for example as happened to me once, if you’ve ever had to have your arm in
a sling or in a cast, it’s very difficult to hold down multiple keys at a time for multi-key combination so what Sticky Notes lets you do is to press
keys in sequence so for example if I wanted to press Shift F to get a capitol
letter or I wanted to press Command Q or Cloverleaf Q to close a window, if I have Stickey Keys
on it would let me press those keys in sequence so I could press the shift key, release it, press the letter key
at my leisure because Stickey Keys is not time dependent and it would function exactly as if I held two
or more keys down at the same time. What slow keys does is for people who have tremors
or who have other issues with their dexterity, it may be difficult to pull your hand away from
the keyboard quickly enough to avoid key repeats so what slow keys does is it slows down that
key repeat or it turns it off altogether. So for example if I had it turned off and I wanted to type the
word “hello”, I would physically have to take my hand off the the L key and repress the key to get that second L. So, again, for people with Parkinson’s with Cerebral Palsy
slow keys can be very very useful. I can also adjust how long i have to hold down
the key until the key repeat is accepted. The fourth item on Universal Access has to do
with the mouse and track pad. and the main utility here is called mouse keys and what mouse
keys lets me do is to use the keypad that’s available on most desktop machines or an
external keypad as my mouse. So, except for the five and zero, all the number
keys would be keys for moving the pointer So, except for the five and zero, all the number
keys would be keys for moving the pointer The five key would emulate a mouse click and
the zero key would initiate a drag. So I could move my pointer over an object, hit the
zero key, hit any of the number keys except five the item would then move in whatever direction I wanted When say I got the item over the trash can where I wanted it
to be, I would simply hit the five key or they escape key and that would function exactly as if I’d done a drag using the mouse. Another very nice feature that’s on the mouse control panel
is the ability to modify the cursor size. So, what I can do with this scrollbar, is to move it over to
the right, the cursor gets larger until it gets quite large indeed or, as I move it back, the cursor gets smaller again. So, for some people with low vision, the issue is not necessarily so much
seeing text as it is being able to visually track the cursor or the pointer, and what this does is it
gives me a larger target to see. or the pointer, and what this does is it
gives me a larger target to see. So those are the items in the Universal Access Control
Panel, which is very much focused on Accessibility. But there are a number of other features built
in to the Macintosh Control Panel that can enhance accessibility as well. And the next one of those that I’d like to
talk about is the Displays Control Panel. If I go into the displays, which is in
the hardware set, I can modify the resolutions So, for example, if I want to go to a display mode that is 800
by 600, your going to see that the text has become bigger. I’m not able to, and the screen has become condensed. I’m not able to, and the screen has become condensed. I can also modify the brightness so that if the standard screen display
is too dark for me to see or is too light for my visual ability or my comfort level, it’s very
easy for me to modify the brightness until, in an extreme case, until I’m not able to see anything. but that’s a very nice feature, again, for people
with low vision who may have certain preferences but that’s a very nice feature, again, for people
with low vision who may have certain preferences that make it easier to see the screen. These
is built in to any OS X Macintosh. This is where I can modify the resolution. If I
want to modify the screen color and appearance, I would go to the General Control panel. and here what I can do is to change the appearance
to either blue or graphite. I can also change It’s being a little slow on me… I can also change the highlight color, so if it’s easier with the
graphite appearance for me to have say the Red highlight color, that is very easy to change. That effects the
overall look of the buttons, menus, and windows. For the highlight color, that effects the selected text. The General Control also lets me effect how scroll bars are shown. I
can have scroll bars shown automatically based on the input device. or only show when I’m scrolling, or always shown, I can modify what the
scroll bar does, I can modify how many recent items are shown so, if someone would get overloaded by having too many items in the Recent
Item list I can modify that to be a smaller number. I also have an option of having LCD
Font Smoothing kick in when available. So, even on the General Control panel, there are a
number of options that can be very useful. So, going on to my next page, on the Keyboard Control Panel, if I click on Keyboard, again I modify the Key
Repeat and the delay until repeat, so, if I don’t want to do that through the Universal Access,
I can do that through the Keyboard Control panel instead. I can also specify that F1 and F2 et
cetera are used as standard function keys which might be useful for example if a third
party piece of assistant technology is dependent on having those standard function keys be in place. I
can also automatically illuminate the keyboard in low light. So, for somebody with low vision who benefits from having
the keyboard illuminated, that can be done automatically in response to the environment. in response to the environment. Keyboard shortcuts can also be modified. Keyboard shortcuts can be very useful
for people who cannot or have difficulty using a mouse. So I can go in under the Keyboard shortcuts feature under the Keyboard
Control panel and modify how the shortcuts are used. For example, if there are standard keyboard shortcuts that’s
conflicting with a shortcut in an application program that i’m using, it’s very easy to go in and change that. So, the last Control Panel I want to
show you is the Mouse Control Panel. And, there are a number of very nice things
here. I can control the Tracking Speed. So if it’s difficult for me to see the standard speed
of those mouse movement, I can slow that down Or, if I want the tracking speed to be faster, I
can modify that. I can modify the scrolling speed. I can modify the double-click speed for some people who have difficulty with double-clicking. It’s very easy to slow down the speed so that I have
a greater window between the first click and the second click For some people, that’s going to make a huge difference. For people who are left handed, they may want to
have the primary mouse button be on the right If you have a two button mouse, that’s very
easy to set through the Mouse Control Panel. And then, as a final nice thing, I promised you a better magnification strategy. What you can do here is set things up so that you can
zoom using the scroll window while holding down the Control key. Or you can modify that to be another key. And
notice here, this gives you, on this computer actually it’s giving you about the same quality of magnification, but that’s a very
easy way to change the level of magnification on the fly. So, Jeanne is going to be showing you a
slide with some information about additional resources and my contact information. I welcome any questions and I
thank you for attending our presentation today. Ok, thank you very much Jane for providing this information. Jane did give us some links to resources
and if you search on IT4U04 in My LINC you’ll bring up a document that
has all of these links live. Reminder that the recording of this session is available
in My LINC on the IT4U webpage. You can also sign up for announcements of upcoming episodes and if you
need any additional help you can contact the ITS Service Center. Thank you very much for today and glad you could join us!
