We developed several questionnaires in the context of this work. They can be downloaded from here in english and french languages. If you use those questionnaires in your work, please cite our reference paper: (paper reference will be added soon).

  • Custom NEI-VFQ 25 (FR/EN): A standard questionnaire commonly used by clinicians to assess quality of life of VIs through 25 questions to address 12 sub-scales: general health; general vision; ocular pain; near activities; distance activities; vision specific: social functioning, mental health, role difficulties, dependency; driving; color vision and peripheral vision. The questionnaire has been slightly adapted in collaboration with the Swiss Association for the Blind and Visually Impaired (SBV); the Driving subscale has notably been replaced by the Sensitivity to luminosity subscale. Individual scores are recoded and transformed on a scale from 0 to 100, where 100 represents the best possible performance and 0 the worst. An average score is calculated for each of the 12 subscales and an average of the subscales scores is calculated to obtain the overall composite score.
  • Difficulties in Recognizing Faces and Emotions (DRFE) (FR/EN): An exploratory questionnaire to assess the functional origins of social difficulties and their impact on daily life. It consists of 14 questions, based on the 5-points Likert scale. The questions address the following topics: difficulty to recognize faces for different familiarity levels; distance at which recognition difficulty starts; negative impact on the person’s daily life; impact of the luminosity conditions; strategies to cope with deficit in face and emotion recognition and general difficulties during social interactions.
  • Expectations on Smart Glasses as Assistive Device (ESGAD) (FR/EN): An exploratory questionnaire to assess the assistive technologies currently used by the visually impaired individuals and their expectations regarding smart glasses assistive devices. The questionnaire consists of 8 questions, based on the 5-points Likert scale, that address the following topics: functional and social daily difficulties, commonly used assistive devices, knowledge of smart glasses technologies, expectations from a smart glasses assistive device, desired information returned by the device on recognized persons and finally importance of comfort and aesthetic of the device.
