  • ACTIVITY ANALYSIS OBJECT REDESIGN

    Using a Vacuum Cleaner to Clean an Apartment

    In the chart below, we’ve tried to break down this chore into basic steps. The Physical, Sensory and Cognitive columns all indicate what type of involvement is needed for that specific task. We did not analyze these steps from a social perspective, as this is usually an activity that is done in the privacy of one’s home.

    Activity Breakdown Physical Sensory Cognitive
    1. clear floor balance/strength/coordination to bend/lift see/sense where objects are located and where to move them to know which objects should be moved and which should not
    2. remove vacuum from storage mobility/strength/balance to maneuver into storage space to get vacuum & attachments see/sense of storage location and space around know the storage location
    3. plug in power cord flexibility to pull out cord and reach socket see/sense the socket location understand that the plug must go into the socket
    4. attach appropriate hose/nozzle hand strength and fine motor skills see/sense appropriate nozzle, location, connection know which attachment is appropriate and their location
    5. turn on vacuum fine motor skills with hands or feet, balance see/sense switch, awareness that it is working/clogged know how to operate the switch
    6. maneuver through space strength to pull, balance/awareness not to trip over cord see/sense where to clean–finding nooks & crannies, location of cord understand back/forth motion and what has been cleaned and what needs to be cleaned
    7. manage locations of cord, vacuum body, hose, attachment strength, coordination see/sense location of cord, vacuum, new socket understand concept of vacuum being attached to the wall and adjusting plug relative to rooms
    8. turn off fine motor skills see/sense the switch understand when finished, how to turn off
    9. unplug fine motor skills, balance, strength see/sense plug understand unplugging as a next step
    10. rewrap cord fine motor skills with hands or feet, coordination see/sense cord without tangling/knots realize cord needs to be wrapped up
    11. return to storage mobility/strength/balance to maneuver into storage space to get vacuum & attachments see/sense of storage location and space around know the storage location

    POTENTIAL ISSUES:

    Vision Impaired

    tripping over cord
    knowing position of all components
    knowing what has been vacuumed
    finding nooks & crannies
    knowing when you run out of cord
    locating new sockets

    Hearing Impaired

    longer response time if plug accidentally comes out of the socket/vacuum is off
    difficult to sense if the vacuum is backed-up

    Restricted Mobility

    the chord could pose a problem maneuvering around and not tripping over
    lifting/accessing machine and attachment

    PROPOSAL:

    A system for moving and managing large objects or devices with a wheelchair. Objects/devices are placed into a storage unit which is mounted on a wall via electro-magnetic powered latches (caribiners). The user backs up to the storage unit, located at wheelchair level, and by pressing switches, located on the armrests of the wheelchair, opens and locks the front latches, securing the unit to the back of the wheelchair, and opens the back latches, releasing the unit from the wall.

    A cordless, rechargeable vacuum cleaner could be adapted using this system. Attachments would be mounted on the wall nearby and all the vacuum controls would be located on the handle of the nozzle.

  • Final Project

    GLOVE DESIGN: In considering the design of the contact points, I did a series of tests with ink and disposable gloves to map out where fingers and thumbs get touch most frequently.

    I decided on copper mesh as the conductive material for the fingertips.

    A finer mesh ended up being the better choice both aesthetically & functionally.

    Final gloves were sewn by hand.

    I decided that a hand-operated control panel would be the other input device (as opposed to foot switches, etc.).
