This paper describes methods of presenting sense of weight in VR for a wide range of masses. Two approaches are proposed; while lifting a virtual object, 1) the object follows participant's hand with delay, 2) the distance between the hand and the object is increased. These approaches were evaluated in a user study that utilized magnitude estimation and gripping force measurements. The results suggest that participants could perceive multiple different weights using both approaches. Moreover, the ratio between minimum and maximum value of magnitude estimations was 3.2 in the first approach and 4.4 in the second approach.
