Study Notes
Input Devices
- Alternative Keyboards: Offer various input methods for users with limited hand or finger mobility. Includes on-screen keyboards, keyguards, joystick keyboards, foot operated keyboards, and adaptive switches.
- On-screen keyboards: Used with touchscreens or pointing devices; users select letters or characters with a cursor.
- Keyguards: Limit the area a user needs to hit on a standard keyboard for more precise input.
- Joystick keyboards: Provide cursor control via physical motion.
- Foot operated keyboards: Input via foot pedals or switches.
- Adaptive switches: Single, toggle, or momentary switches, activated by hand, head, or body movements. Can be integrated into customized keyboards.
- Head tracking: Systems using sensors to detect head movements and translate them into cursor control commands. Suitable for users with limited hand or limb use.
- Voice Recognition software: Users dictate text or issue commands with voice commands, removing the need for physical typing.
- Eye Tracking Systems: Track eye movements to control the cursor or select items on the screen, suitable for users with limited limb movement.
- Specialized Stylus and Tablets: For use with tablet computers, these allow for more precise and controlled input compared to standard touch screens.
Output Devices
- Screen Magnification Software: Enlarges the display of text and content, accessible for users with visual impairments.
- Text-to-Speech Software: Converts text displayed on the screen into speech or audio, accessible for users with visual impairments.
- Alternative Displays: Include braille displays, converting text to braille, making text content accessible to blind or visually impaired users.
- Large-Print Monitors: Displays images, text and graphical content in oversized text or displays, improving visibility for users with limited or impaired vision.
- Headphones and Speakers: Allow users to enjoy audio-based experiences; connectable to alternative input devices or voice recognition software audio output.
Considerations for Usability and Accessibility
- Ergonomic design: Devices should be physically comfortable and easily adjustable to conform to the user's body; adjustable chairs, height-adjustable monitor arms, and specialized keyboard placements.
- Customization options: Devices should offer settings to adjust sensitivity, speed, and other parameters to users' unique physical limitations or personal preference.
- Intuitive interfaces: Systems incorporated into the design of these output/input devices should be user-friendly, requiring minimal training for efficient and effective use.
- Compatibility and Integration: Devices need to seamlessly integrate with standard computer systems and applications the end-user is familiar with.
- Testing and Evaluation: Careful user testing for input/output devices is vital to evaluate and adapt devices to individual user needs.
- Physical access and accessibility considerations: Ensure the device's location, controls, and functionality are easily accessible from various angles and postures, considering the user's physical posture/movement requirements.
- Cost-efficiency: Devices should be affordable/cost-effective in their application and maintenance, considering the particular challenges faced by the user.
