Trackpads in the Computer Lab

I am a special education teacher who supervised a technology lab for twenty five years. The lab had specialized software, adapted mice, additional adapted hardware, and picture symbol communication aids for students whose significant disabilities made it difficult for them to use the general computer lab. I taught students who could not climb the stairs to my lab in their classrooms. I also assisted teachers and other personnel in my school with their technology needs as time permitted. Before moving to the technology lab, I was a classroom teacher with a classroom computer that students and staff could use. Now, I am a semi-retired substitute teacher.
