Title
An Assisted Photography Framework to Help Visually Impaired Users Properly Aim a Camera
Abstract
We propose an assisted photography framework to help visually impaired users properly aim a camera and evaluate our implementation in the context of documenting public transportation accessibility. Our framework integrates user interaction during the image capturing process to help users take better pictures in real time. We use an image composition model to evaluate picture quality and suggest providing audiovisual feedback to improve users’ aiming position. With our particular framework implementation, blind participants were able to take pictures of similar quality to those taken by low vision participants without assistance. Likewise, our system helped low vision participants take pictures as good as those taken by fully sighted users. Our results also show a positive trend in favor of spoken directions to assist visually impaired users in comparison to tone and silent feedback. Positive usefulness ratings provided by full vision users further suggest that assisted photography has universal appeal.
