Interactive collaboration in distance learning based on remote control of server session

This paper is devoted to description of environment for distance lessons, suitable for both remote lectures and hand-on trainings for mastering of particular software products. Proposed solution is based on interception of student's remote session on the server by teacher having administrator's rights. As a result we have managed to create a virtual computer with two sets of controls - two keyboards, two mice, two screens. One control set is located on the teacher's side and the other - on the student's side. That gives the ability to teacher and student to share the same instance of software product under study.
