This paper describes a set of visual cues of contact designed to improve the interactive manipulation of virtual objects inindustrial assembly/maintenance simulations. These visual cues display information of proximity, contact and effort between virtualobjects when the user manipulates a part inside a digital mock-up. The set of visual cues encloses the apparition of glyphs (arrow, disk, or sphere) when the manipulated object is close or in contactwith another part of the virtual environment. Light sources can also be added at the level of contact points. A filtering technique isproposed to decrease the number of glyphs displayed at the same time. Various effects -such as change in color, change in size, anddeformation of shape- can be applied to the glyphs as a function of proximity with other objects or amplitude of the contact forces. A preliminary evaluation was conducted to gather the subjective preference of a group of participants during the simulation of anautomotive assembly operation. The collected questionnaires showed that participants globally appreciated our visual cues of contact.The changes in color appeared to be preferred concerning the display of distances and proximity information. Size changes anddeformation effects appeared to be preferred in terms of perception of contact forces between the parts. Last, light sources wereselected to focus the attention of the user on the contact areas.
