Virtual Path Integration Task

 

Description: This task assesses path integration in a desert-like virtual environment. It is a virtual analog of real-world path completion tasks and tests how well one infers a direct path of return based on the perception of optic flow information. A passive outbound travel phase ensues before a homebound/homing phase, in which subjects/players must find the most direct path of return to the point of origin. Simple paths were intermingled with complex paths, with the former featuring single turns and the latter featuring double turns during the outbound phase. Dynamic recording of path integration performance occurs in the form of distance and direction/turning errors (signed and unsigned), and homing latencies (i.e., time taken to return to the start from the terminus of the outbound path). A practice version of the task must be administered before the official test session.
