These are some of the key areas of the design. Having these measurements to use as a guide for my design as well to see possible opportunities to design for with the existing mobility devices leaving room for improvement.

This diagram depicts the minimum clear width required by users of manual wheelchairs, powered wheelchairs and scooters to complete a 90-degree turn.
. The findings from the table above indicate that a width of at least 85 cm was required for 50% of the manual and power wheelchair users measured in this study to perform a 90-degree turn.


A width of 100cm was required in order for 95% of manual wheelchair and power chair users to complete the turn, with 95% of scooter users needing a width of at least 110 cm.  This data is based on measurements of wheeled mobility users performing 90- degree turns in a hallway, built with mock walls.

anthro 4This shows the minimum dimensions for the rectangular floor area required by occupied wheeled mobility devices (i.e., with the occupant seated in their own wheeled mobility device) when stationary. This is key for use in public areas including trains, buses, movie theaters and sports stadiums). The clear floor area width dimension also informs the minimum clearance width for successful passage through corridors, doorways, and wheelchair ramps. Currently, the accessibility guidelines prescribe a minimum floor area of 760 x 1220 for wheeled mobility access. The data indicates a minimum clear floor area of 786 x 1362 mm. for manual chairs, 827 x 1414 mm (33 x 56 in.) for powered chairs, and 837 x 1435 mm (33 x 56 in.) for scooters.

anthro7It references dimensions of clearance height and depth to the forward-most abdomen point on a person in relation to the built environment (tables etc). Shaded areas depict the amount of space required by the specified percentage of people if positioned with the abdomen touching an obstruction. This highlights a potential conflict with my design, as I want to increase the seating height for the user to be closer to eye level with a standing person, it will mean it wont be able to interact with table, desks etc very well. (user will have to use a chair instead)
