Sign Linguistics

Plain verbs do not give morphological information of person and number by movement. We can be told this information but it is shown in separate signs or by non-manual features such as eye-gaze or body-orientation. Plain verbs do sometimes move through space but this is not a "morphological" movement. It is usually because they are formed by visual motivation and the movement is needed to show the movement of the action described by the verb (e.g. SWIM or WAVE).
