Procedure for Part I - Overlay Test and Tactile Icon Evaluation at ABVI

The steps we followed for Part I of the study - overlay test and tactile icon evaluation at the Association for the Blind and Visually Impaired (ABVI). Participant data and test comments/discussions were recorded by hand on prepared test forms. Except for the finger measurements and a couple pictures, no other audio or video was recorded.

Consent Form - Test participant signs the consent form. Provide a signature plate to guide the test participant's pen to the form's signature area.

Record Test Participant Data - Age group, visual ability, braille literacy.

Finger Measurement - Measure the width of the right hand index finger just below the start of the finger nail. Place the test participant's right index finger on grid paper and snap a picture.

Test Fixture Overview (sitting) - Provide an overview of the test fixture and the layout of the buttons using the touchplate overlay.

Test Fixture Familiarization/Training (standing) - Introduce the test fixture and the two test scenarios - heating a beverage and finding a button

Overlay Tests - for each of the four overlays (standing)

----- Heat a Beverage Scenario

----- Find a Button Test

----- Likeability/Acceptability Questions

Tactile Icon Evaluation (sitting) - Test participants review and comment on variations of six different tactile icons.

Discussion - Followup discussion on the procedure, overlays and their personal experiences with home appliances.
