1. Access
AT Bootcamp
ATIA 2013
Behnke, Marotta and
Wojcik
2. Topics to be Covered
Accessibility: Features Built into
Operating Systems
Touch Devices Accessibility Issues
Using Switches to Create Access
Making Computers
Accessible
4. Information About OS Accessibility
Apple –
◦ http://www.apple.com/accessibility/
Windows
◦ http://www.microsoft.com/enable
Android
◦ Google – Android Accessibility Overview
8. The Touch Screen
◦ Doesn’t require pressure, only contact.
◦ More sensitivity may help some, but
may be a hindrance to others.
◦ There are some adjustments that can
be made to the touch screen. How
effective are they?
10. Training app suggestions to improve
direct access

16. Switches: Consideration
Switch Types
Access Method
Access Site
Mounting
Function
◦ Direct Select
◦ Scanning
Interface to other AT
17. Switch Types
Plate
Lever
Eye Blink
Infrared
Sound
Proximity
Pneumatic
….. and so many more!
18. Which Switch?
Focus on Features
◦ Amount of force/pressure
◦ Amount of travel
◦ Size of the target
◦ Color and Texture
◦ Feedback
Visual—lights
Auditory—Click sound, music, beep
Vibration
Physical—
Feeling of movement
20. Switch Sites
◦ What do you want the
person to be able to do?
◦ What have they already
tried?
◦ Where are they accessing
switch?
◦ Observation
◦ Consistent / reliable
movement
53. Consideration: Mouse Alts
◦ What does the
person need to do?
◦ What have they
already tried?
◦ Observation
◦ Consistent / reliable
movement
◦ Where are they
accessing computer?
56. Other Considerations….

Hands on activity – explore everyday tech devices within the room. Share your device with others – explain some of the built in accessibility features that you felt were important.Complete the Google Doc on the WIKI page. We will go over these as we move through presentation
Is this good for the consumers you serve??Discussion – use the backchannel and then share with group
Can your consumer complete these types of gestures?Cognitive demand – remembering these gestures. Gestures change depending on device. Different apps require ability to complete different gestures
Look for pointing/tap, swiping, and dragging.
Hands on activity – explore switches within the room. Explore the variety of switches – plug them into any devices that might work with them.Complete the Google Doc on the WIKI page. We will go over these as we move through presentation
Pix:Bottom right – Enabling Devices – Blink SwitchTop Right – AbleNet Pneumatic SwitchMiddle - SCATIR Switch Deluxe The Self-Calibrating Auditory Tone Infrared (SCATIR) Switch is a momentary-contact optical switch with auditory feedback that works by detecting a beam of reflected pulsed infrared light. The SCATIR Switch can be controlled with an eye-blink, eyebrow movement, finger movement, head movement, and facial muscle movement. Recommended for users who have difficulty activating push-button switches.Includes switch, sensor, eyeglass and gooseneck mounting kit.Used to Adjust:Beep on/offTone continous/beepManual or self calibrationPlate switches are activated by pushing and come in many sizes.Lever/Wobble switches are activated by moving the lever.Microlite switches are designed to require less pressure to push.Sound Activated switches are activated by a consistent sound.Eye Blink switches are activated by an eye blink.Infrared switches are activated by a movement that breaks the infrared beam.Mercury/Tip switchesare activated by tilting the switch.Sip and puff switches (pneumatic switches) are activated by sipping or puffing.Wireless switchesperform like regular switches, but without the cords.Proximity switches are activated by moving a body part close to the switch. These are helpful for people with some movement, but are not able to push a switch because of limited strength.And so many more…..

I would like to take this opportunity to introduce our new product which I feel may be of interest to you.Pererro, a unit measuring just 30x28x9mm, connects directly to an iPod (4th generation), iPhone (4S, 4 & 3GS) or iPad (3rd generation, 2 or 1) and allows users to switch access the iOS by connecting any single switch to pererro.We feel that this is a much needed device that will make Apple’s i-devices readily available to everybody, regardless of their condition.pererro, is also customizable by downloading the associated app where users can configure the device to suit them, options include;scanned method (auto-increment & press to increment),Scan Interval timeMenu Pause Time and more.We will be demonstrating the product at booth #108 and would welcome any questions or queries you may have.We will also be available all Tuesday, 29th January if you would like to arrange an informal meeting.We believe that this will be the market leading Switch Access device for i-devices and will be a game changer in how we, as an industry look at utilising their capabilities.For further information please contact me directly.
