This paper introduces preliminary works on building an experimental end-user evaluation for dual-user haptic systems for hands-on training. Such systems bring together the advantages of haptic computerbased training systems and those of supervised training where an expert trainer actively helps in the learning process. The first results mainly permitted to highlight several technical and organizational issues to overcome in a close future. The objective of this project is to test other architectures such as those listed in the state-of-the-art section, to provide comparative conclusions about the pros and cons of each one.
