You are invited to participate in a study that will be carried out in a lab to evaluate the usability and effectiveness of the warning interface for a remotely supervised prototype autonomous agricultural machine. The study should take no longer than one hour to complete.
Role of Participants:
You will be asked to do the following:
- Conduct an internet search task to answer specific agronomic questions (on a screen) and then move focus to another computer monitor (where you will be informed about the statutory information of a simulated autonomous machine using combination warning methods- visual-auditory and visual-tactile).
- You are to select the right choice of condition based on perceived warning from a list of possible conditions to acknowledge comprehension.
- You will be presented with a computer system usability questionnaire (CSUQ) and an end-of-session questionnaire to rank each warning mode(s) and give your personal experience during the entire experiment respectively.
Inclusion/Exclusion Criteria:
Potential participants must be willing to submit to auditory, visual, and tactile screening with farming experience (i.e., individuals actively engaged in farming) and should be in the age bracket of 18-65 years old. Participants who are less than 18 years old or more than 65 years old would not be eligible. Also, participants with impaired vision and hearing would be ineligible.
