Our Client
 Peter
 Age 17
 Junior at Lowell Catholic High School
 Suffered a stroke at just ten days old
 Has cerebral palsy
 Lost total motor control over the left
side of body
Objectives
• Design a videogame controller that can be
used with all modern game systems.
• Design it in such a way that Peter will be
able to access all of the functions
effectively with one hand.
• Consider aesthetics to minimize muscle
effort required to use said controller in
order to prevent Repetitive Motion
Disorders (RMDs).
Preliminary Research
 One handed controllers do
exist, but their aesthetics
make them unusable on a
regular basis.
 Not all aspects of a controller
are used at all times in most
games.
 A standard game controller
has 8 buttons, a 4-direction
pad and 2 analog “control
sticks”, each with two axis’.
Solution
•Standard Joystick is used as a
base and functions as primary
analog axis.
•The circuit for interface with the
game console will be removed
from a universal game controller.
Mode switch
•Buttons placed under inside of
fingers (“shoulder”) and finger
tips.
•Analog stick placed on top of
joystick, to be used by thumb
•Mode switch allows either of the
analog sticks to alternately
function as the directional pad,
depending on game being played.
Electronics
 A circuit to convert the analog signal
created by the sticks into 4 discrete state
digital signals for the directional pad.
 A circuit to switch the signal routing
between each of the analog sticks based
on the mode switch.
