Documentation for Room-Size Estimation Data
--------------------------------------------

In the accompanying csv file (LeggeEtAl_RoomSizeEstimates.csv):

Column A: Subjects
	S01-S32: Normally Sighted Subjects
	LV02-LV18: Low Vision Subjects
	B02-B17: Blind Subjects

	*S04 did not complete room size estimation, and is not included here.

Column B: Room 
	Column B lists the seven test Rooms (A-G). The dimensions of the rooms are listed in a table below.

Column C: Door Side Length (ft)
	Measurement of the physical door side length of the room

Column D: Door Side Subject Response (ft)
	Subject's Response for the door side value

Column E: Non-Door Side Length (ft)
	Measurement of the physical non-door side length of the room

Column F: Non-Door Side Subject Response (ft)
	Subject's response for the non-door side value

Column G: Comments

Documentation for Spatial Updating Data
--------------------------------------------

In the accompanying csv file (LeggeEtAl_SpatialUpdatingEstimates .csv):

Column A: Subjects
	S01-S32: Normally Sighted Subjects
	LV02-LV18: Low Vision Subjects
	B02-B17: Blind Subjects

Column B: Visual Conditions
	Control: Normal vision, no restriction (able to look back at entrance and/or target bean bag). 
	Forward Facing: Normal vision, no goggles, no headphones, face forward (not able to look back at entrance and target bean bag).
	Preview: Subject given 10 seconds to look in the space from the door before putting on blindfold and headphones.
	Auditory: Normal and Low Vision subjects were blindfolded, and had no visual exposure to the room before or during the updating trials. 
	Deprivation: Normal and Low Vision subjects were blindfolded, and all subjects wore noise-reducing earmuffs. 

Column C: Room/Path #
	Lists the seven test spaces (A-G).  X refers to an eighth room where subjects were given practice trials and where five paths, numbered 1-5, were used for control trials for spatial updating. 

Column D: Starting Distance (ft)
	Measurement of the physical distance from subject at the end of the path to the starting point

Column E: Starting Distance Subject Response (ft)
	Subject's estimate of the  distance from their location at the end of the path to the starting point

Column F: Starting Direction (deg)
	Measurement of the angle in degrees from the subject's facing direction at the end of the path to the starting point

Column G: Starting Direction Subject Response (deg)
	Subject's estimate of the angle from their facing direction at the end of the path to the starting point

Column H: Target Distance (ft)
	Actual distance (true value) from the subject at the end of the path to the target beanbag dropped at the first waypoint of the path

Column I: Target Distance Subject Response (ft)
	Subject's estimate of the distance from their location at the end of the path to the target (beanbag dropped at the first waypoint of the path)

Column J: Target Direction (deg)
	Measurement of the angle in degrees from the subject's facing direction at the end of the path to the target (beanbag dropped at first segment of the path)
 
Column K: Target Direction Subject Response (deg)
	Subject's estimate of the angle from their facing direction at the end of the path to the target (beanbag dropped at the first waypoint of the path)

Column L: Comments
