Checkpoint 6.1: Test for accessibility

Test for accessibility using the techniques in each checkpoint.

On this page:

 

Rationale

Accessibility must be included as part of the product test cycle to insure people with disabilities can use the product. After the product has been created, check to ensure that it complies with accessibility requirements. Several techniques are available to verify that the product is accessible to people with disabilities. See the individual checkpoints for specific tests for each checkpoint. The tools used to test accessibility are outlined below.

Required development techniques

The following techniques are the minimum required to meet Checkpoint 6.1 from the IBM Hardware Accessibility Checklist:

The above techniques are required; the following techniques are recommended to enhance accessibility.

Required test techniques

Test the hardware to ensure that it complies with accessibility requirements.

Tools

The following table summarizes the tools available to test hardware products for accessibility. There are no tools available at this time that can automatically test for any Hardware Accessibility standard.

Techniques

Hardware Accessibility Test Tools
Checkpoint Test Tools
1.1 Controls and latches should be reachable and operable with one hand and minimal dexterity. Automated: N/A
Manual: Torque or force gauge and measuring tape to check force of control and distances to vertical plane.
1.2 Provide alternative forms of user identification for biometric identification. Automated: N/A
Manual: Check that a user can be identified using other than biometric means.
1.3 Provide an alternative input method for touchscreens or touch-operated controls. Automated: N/A
Manual: Torque or force gauge to check force of control.
2.1 Provide the status of all locking or toggle keys visually and either through touch or sound. Automated: N/A
Manual: Visual verification.
2.2 Provide keys which are tactilely discernible without activating them. Automated: N/A
Manual: Visual or tactile verification.
2.3 If key repeat is supported, the delay before repeat shall be adjustable to at least 2 seconds Key repeat rate shall be adjustable to 2 seconds per character. Automated: N/A
Manual: Visual verification.
3.1 Provide industry standard ports for alternative input and output devices. Automated: N/A
Manual: Visually verification, specification verification and a sound level meter.
4.1 Use color as an enhancement, not as the only way to convey information and distinguish keys, controls and labels. Automated: N/A
Manual: Visual verification.
5.1 Provide an interface so that use of system sounds can be known to software. Automated: N/A
Manual: Inspection of the specification and software test cases.
5.2 Provide a physical volume control or provide an interface so that volume can be controlled with software. Automated: N/A
Manual: Visual verification, specification verification and software test cases.
