Assessing Access Methods

Assessing Access Methods

Finding the best access method can be challenging, whether for computer input or a communication device. Will the user use direct selection (e.g., mouse, touchscreen, eye gaze), or will they need indirect selection (switch/scanning)?

Goals and Assessment

When determining the best selection or input method for an individual, there are five important considerations:

  • Accuracy: Does the input method allow the user a high level of accuracy in making selections?
  • Control: Does the user have voluntary control for every selection needed?
  • Endurance: Does the user consistently use the identified body part and selection method repeatedly without fatiguing quickly?
  • Reliability: Can the user reliably and repeatedly use the identified body part and selection method?
  • Speed: How fast can the user make selections, whether through a mouse, typing, touchscreen, or scanning?

When we consider these factors, the next step is evaluating and collecting data to compare potential input methods. The Compass Software for Access Assessment is a great tool to help you measure the effectiveness of an access method. It's also great to diagnose selection method difficulties, identify the best mouse and keyboard alternatives, switch use, and plan training.
