Phase 2: Design & Implement
Design Question
-
How will your interface handle the following inputs and outputs: voice, mouse, keyboard, touchscreen?
- The interface design should take into account a variety of input devices. For instance, users with touchscreens may need interactive elements to be larger and spaced out to avoid selecting the wrong one.
Tip
- Include “help” in the label of the chatbot activation button for users who use the term help when searching for content.
Phase 3: Test & Evaluate
Self Check
-
The chatbot offers functionally equivalent experiences (i.e., communicates the same content and enables the same tasks) through visual and non-visual means.
-
Does the chatbot offer visual and audible notifications?
Ask the User
-
Were you able to complete your task the way you prefer to communicate using technology such as keyboard and mouse, speech-to-text, screen reader, etc.?
- This question is subjective; use a Likert scale. This question should be asked post-study.
-
Can you interact with all interactive elements in the chatbot with your input modality of choice?
- This question could be subjective or objective. This question can be asked mid-study or post-study.
