Adaptation of the pencil-and-paper CTT to yield the DOME-CTT. a Trails A (left) and B (right) tasks from the pencil-and-paper CTT. The first and last balls are each indicated by a picture of a hand (pointing and stop signing, respectively, seen here in Trails B only). b Schematic depiction of the spatial geometric orgnizaiton of the target balls in the three dimensional space. c Trails B task from the DOME-CTT, as viewed by the participant. Ball size varies as a function of its proximity to the participant in the VR space. A fixed pointing stick marker is represented by the red ball. Its trace is depicted in yellow, while the red, more pronounced trace is used for visual feedback in the VR space. The first and last balls are indicated using the hand icon
