Study conducted to compare the orientation and mobility observational skills among nine university students and nine certified orientation and mobility specialist via digital video assessment. The video assessment consisted of three continuous travel clips of approximately two minutes each. The clips were taken of the participants traveling with a long cane in variety of settings, including: (1) indoors, (2) a residential area, and (3) a business district. The researchers planned four to five technical errors, as a response form was used to rate how well the students identified the errors through observation. The students found an average of 9 of the 14 planned errors, while the orientation and mobility specialists found an average of 8.9. The students were also found to differ from the orientation and mobility specialists in their interpretations of the errors, as they gave considerably less detailed responses and explanations. Implications for improvements in video assessments are discussed.
