Screenshot of the tasks in V+ conditions with additional map of haptic elements: The visual environment displays sound icons (e.g., a bell or hands clapping) within sound zones (SZ), and a grey square that marks the center zone (CZ). SZs and CZ (wave-marked areas) are active zones where a vibrotactile haptic feedback is provided. The scene is limited by two haptic walls (HW, solid lines). HWs (dotted lines) limiting CZ are only turned on in the game phases where only the left or the right game zone is used. The red circle is the game “cursor”. All units are in centimeters
