Abstract
This project researched haptics and object physical properties to ascertain whether some specific properties are more important than other ones, and what level of mismatch is tolerable between a physical prop and a virtual object representing the prop. Two objects have been chosen, a pan and a hammer to test the mismatch between the versions. The chosen properties were surface texture, size, and shape. Different papers have been analyzed which include techniques that can be used to perform the experiment. The two objects were modelled and textured to resemble the real-world objects as best as possible, and their surface texture, size and shape were given three levels of fidelity, with 0 being the most inaccurate. An evaluation was performed at Aalborg University Copenhagen campus, but due to the COVID pandemic the sample size was very small. Regardless, the data was analyzed and the results show that size is more important than surface texture and shape when matching virtual props with physical objects. The data also showed that surface texture and shape could be at fidelity level 1 to register a match between the virtual object and physical prop.
