Subtle gaze manipulation for improved mammography training Conference Paper uri icon

abstract

  • We use the Subtle Gaze Direction technique (SGD) to guide novices as they try to find abnormalities in mammograms. SGD works by performing image-space modulations on specific regions of the peripheral vision to attract attention. Gaze is monitored and modulations are terminated before they are scrutinized with high-acuity foveal vision. This approach is preferred to overt techniques which permanently alter images to highlight areas of interest. SGD is used to guide novices along the scanpath of an expert radiologist. We hypothesized that this would increase the likelihood of novices correctly identifying irregularities. Results reveal that novices who were guided in this manner performed significantly better than the control group (no gaze manipulation). Furthermore, a short-term post-training lingering effect was observed among subjects guided using SGD. They continued to perform better than the control group once the training was complete and gaze manipulation was disabled. 2012 ACM.
