We propose a selection method, "target reverse crossing," for use with camera-based mouse-replacement for people with motion impairments. We assessed the method by comparing it to the selection mechanism "dwell-time clicking," which is widely used by camera-based mouse-replacement systems. Our results show that target reverse crossing is more efficient than dwelltime clicking, while its one-time success accuracy is lower. We found that target directions have effects on the accuracy of reverse
