Abstract

The ability to direct viewer gaze about an image has important application in medical image training and analysis. We use a novel gaze manipulation technique called Subtle Gaze Direction [Bailey et al. 2009] to guide novice users as they try to identify abnormalities in digital mammogram images. Subtle Gaze Direction is achieved by performing brief image-space modulations on specific regions of the viewer's peripheral vision in order to attract their attention. The viewer's gaze is monitored in real-time and the modulations are terminated before the viewer is allowed to scrutinize them with their high-acuity foveal vision. This approach is preferred to more overt techniques which require permanent alterations to the original images in order to highlight specific areas of interest. In our experiment we use Subtle Gaze Direction to guide novices along the scanpath of an expert radiologist. We hypothesized that this approach would increase the likelihood of novices correctly identifying irregularities in the mammograms.

微妙的凝视操纵，以改善乳房x光检查训练

引导观看者注视图像的能力在医学图像训练和分析中有着重要的应用。我们使用一种名为“微妙凝视方向”的新颖凝视操纵技术[Bailey等人，2009]来指导新手用户识别数字乳房x光照片中的异常。微妙的凝视方向是通过对观看者周边视觉的特定区域进行简短的图像空间调制以吸引他们的注意力来实现的。观看者的目光被实时监控，在观看者被允许用他们的高灵敏度中央凹视觉仔细检查他们之前，调制被终止。这种方法是首选更明显的技术，需要永久改变原始图像，以突出特定的兴趣区域。在我们的实验中，我们使用微妙的凝视方向来引导新手沿着放射科专家的扫描路径。我们假设这种方法将增加新手正确识别乳房x光检查异常的可能性。
