Abstract	The implementation of an interaction between a user and a Virtual Environment (VE) in Virtual Reality (VR) may use various techniques. However, in some cases, the interaction must be very precise and comfortable for the user. In this paper, we introduce a new selection and manipulation technique called FOLLOW-ME. The model associated to this technique splits the Virtual Environment into three zones in which a specific interaction model is used: a free manipulation zone, a scaled manipulation zone and a precise manipulation zone. Each one of the three zones is characterized by a specific interaction granularity which defines the properties of the interaction in the concerned zone. This splitting is created in order to have both precision near the object to reach or to manipulate (scaled and precise manipulation zones) and to maintain a realistic and free interaction in the VE (free manipulation zone). In the precise manipulation zone, we use the concept of virtual guides in order to assist user. In this paper, we exhibit the formalization of the model associated to the FOLLOW-ME technique. Then, we both compare our technique with classical interaction techniques in the case of a task which consists in trying to reach an object in VE and give some insights about the conditions of usefulness of virtual guides in a selection task. Some preliminary experimental results are presented and discussed.
