Background A simulation environment for magnetically-driven, active endoscopic capsules (Abu-Kheil Y, Seneviratne L, Dias J, A simulation environment for active endoscopic capsules. 2017 IEEE 30th international symposium on Computer Based Medical Systems (CBMS), Thessaloniki, pp 714-719, 2017), can perform four main operations: capsule tele- operation, tracking of a specific region of interest, haptic feedback for capsule navigation and virtual reality navigation.Methods The main operations of the simulation environment can be clinically evaluated. In this paper, we proposed a clinical evaluation for the main functions of the simulation environment. There main testing procedures for the navigation strategies are proposed; i) vision-based tele-operation, ii) vision/haptic-based navigation without head control, and iii) vision/haptic-based navigation with head control. The navigation ways can be compared with each other in terms of introduction time, visualization and procedure comfort. Human-subject studies are to be conducted in which 20 students and 12 expert gastroenterologists participated.
