Deconstruct an Interaction: OCAD Annex Building Doors

The doors to OCAD’s Annex building are used daily by hundreds of students and teachers who wish to gain access to the facilities in this building, including the library, learning center, food court and various classrooms.

Logically, these doors should be easy to use and an efficient design, but our research has uncovered several glaring flaws in the current setup. In our research, we discovered that though the process is theoretically quite simple (grasp handle, pull/push door open, proceed through), there are numerous factors, including crowding, personal baggage load, arm usability and confinement to a wheelchair that could force one to halt the interaction until one is able to ask another for assistance. We found that the majority of students consider the doors too heavy and difficult to open, especially when one is carrying numerous items such as art supplies. In addition, there is currently no automatic open for wheelchair access and the small size of the doors in relation to the opening creates a bottleneck effect which leads to excessive crowding.


1.)    Replace the current doors with automatic sliding doors to eliminate usability problem, allow wheelchair access and expand usable space.

1.)    Shift entrance doors forward to near sidewalk and replace current doors with our custom double automatic sliding door setup. This setup will eliminate difficulties with opening the doors, improve doorway size and eliminate the bottleneck and opposing flow problems by splitting the traffic entering and exiting into two separate doors.
