Validity and diagnostic performance of a virtual reality-based supermarket application "MEMOSHOP" for assessing episodic memory in normal and pathological aging.

Objective: MEMOSHOP is a virtual reality (VR)-based supermarket application for assessing episodic memory in aging. The aim of this study was to examine its construct validity against the gold standard paper-and-pencil neuropsychological test for clinical memory assessment in mild cognitive impairment (MCI) in older adults.

Methods: Patients with isolated subjective cognitive complaints (SCCs) or MCI were recruited in the Bordeaux Memory Clinic (MEMENTO cohort).

Touch-based interfaces for interacting with 3D content in public exhibitions.

A museum exhibition on the Lascaux caves provides the opportunity to experiment with touch-based interfaces manipulating 3D virtual objects. The researchers targeted three tasks: observing rare objects, reassembling object fragments, and reproducing artwork.
