Navigation system mode: Argus Vision
"This intervention uses the navigational aid with the output sensory modalities configured as follows:~* Vision: Argus mode~* Haptics: none~* Audio: none Since this mode only provides the standard Argus vision, it is equivalent to using the base Argus II system without the navigational aid."
Navigation system mode: Depth Vision
"This intervention uses the navigational aid with the output sensory modalities configured as follows:~* Vision: Depth mode (at Argus II resolution and field-of-view)~* Haptics: none~* Audio: none"
Navigation system mode: Depth Vision with Haptic / Audio
"This intervention uses the navigational aid with the output sensory modalities configured as follows:~* Vision: Depth mode (at Argus II resolution and field-of-view)~* Haptics: yes~* Audio: yes"
Navigation system mode: Haptic / Audio
"This intervention uses the navigational aid with the output sensory modalities configured as follows:~* Vision: none~* Haptics: yes~* Audio: yes Since this mode does not provide any visual feedback, it is equivalent to using navigational aid completely blind without a visual prosthesis."
Navigation system mode: High Field-of-View Depth Vision
"This intervention uses the navigational aid with the output sensory modalities configured as follows:~* Vision: High Field-of-View Depth mode (at twice the Argus II resolution and field-of-view along each dimension)~* Haptics: none~* Audio: none"
Distance test vision mode: Low Resolution / Low Field-of-View
"This intervention performs the relative distance to two obstacles test with the user's vision output configured as follows:~* Resolution: Low~* Field-of-View: Low"
Distance test vision mode: Low Resolution / High Field-of-View
"This intervention performs the relative distance to two obstacles test with the user's vision output configured as follows:~* Resolution: Low~* Field-of-View: High"
Distance test vision mode: High Resolution / Low Field-of-View
"This intervention performs the relative distance to two obstacles test with the user's vision output configured as follows:~* Resolution: High~* Field-of-View: Low"
Distance test vision mode: High Resolution / High Field-of-View
"This intervention performs the relative distance to two obstacles test with the user's vision output configured as follows:~* Resolution: High~* Field-of-View: High"
