Design of haptic interfaces for precise bimanual manipulation should take into account how weight simulation is implemented when manipulation switches between one and two hands. The importance of this is apparent in tasks where the user requires to apply vertical forces to penetrate a surface with a tool or splice a fragile object using one and/or two hands. Accurate perception of simulated weight should allow the user to execute the task with high precision. Here, we evaluated unimanual and bimanual weight perception when lifting virtual boxes of different weights with precision grip in a coupled Master Finger 2 setup. Initial results with virtual weights are similar to results from studies which used real weights  even though the users appear to be less sensitive to virtual weights. Implications for haptic interface design are discussed.
