在像素和度数之间转换
A very useful online visual angle calculator that converts between pixels and degrees. The perfect tool for figuring out the size of your stimuli, where to position objects in your eye-tracking task, or how far away your screen should be. Enter your screen resolution, dimensions, and distance on the left, then choose the appropriate tab on the right. Use “Centered” for objects centered on the screen (or the screen itself). Use “One Sided” to compute the distance of objects (e.g. targets in saccade tasks) from the screen center. Use “Off Center” to compute the size of objects that are offset from the screen center. Enter degrees of visual angle or pixels on the right – the app converts from pixels to degrees and from degrees to pixels. You can find out more about how the calculator works in this blog.
