2. Abstract
This week, our four-man team was tasked with creating an
innovative game controller for a user that has impaired use of
one hand. Through this presentation of 25 slides, our team will
showcase our combined core design concepts and introduce the
ODIN controller. The ODIN’s design meets industry standards in
usability and includes our own thought process inspirations, the
design purpose, methodologies, and assumptions. We have also
created detailed schematics and a working prototype. With this
prototype we performed playtests and documented the findings
in the presentation. Through our explanations and analysis we
hope to give you, the reader, a better understanding of our
processes and hope you will come to see the necessity of the
ODIN and other accessible controllers like it.

3. Introduction
Our goal for ODIN was to allow someone who has an
impaired use of one hand to still be able to play
modern video games with the same efficiency as
someone using a standard (two handed) controller.
This level of accessibility was key to our design as well
as our overall design process. Through this process we
came up with ODIN (Omni Directional Interface
Nexus) and have designed it to accomplish the ease of
use and productibility of modern game controllers.

4. Design Purpose
● Implement a controller design that is familiar to the user,
has a low skill requirement and as small learning curve as
possible.
● The controller design is targeting someone who is one
handed or has a disability that limits the use of one
hand/arm.
● A ergonomic, smooth, and natural feel of both the
controller and the input mechanisms using either hand.
● Our design utilizes an ten button design that simulates the
major buttons of most modern controllers.

5. Jeff’s Inspirations
● My inspiration came from a
combination of a mouse, which I
love using for games, and the
Cyborg Command Unit (picture
on the bottom right)
● I took those two controllers and
considered how I would play a
game using only one hand and
while sitting on the couch (which
is where most gamers play
consoles)
● My conclusion was that the
controller would need to be
attached the the user in some
way so that playing didn’t require
a flat surface to stabilize the
controller

(Houchens, 2015)

6. Dakota’s Inspirations
● My inspiration came from a
video I watched of a man who
makes modded one handed
360 controllers.
● His idea of putting the analog
stick on the bottom of the
controller to use with his knee
was a major design concept for
me.
● The last bit of inspiration was
the fact that I have played
games one handed before and
used different methods to
move the left analog stick.

7. Kyle’s Inspirations
● I was inspired by several current
controllers when I designed
PALM. Mainly, the Steam
Controller’s touchpad utility
combined with the 3D area
cameras similar to the Microsoft
Kinect system.
● I was also inspired by the child
game Simon for the button
colors and configuration. This
allowed for a simple,
recognizable system for
everyone.
● The main overarching design
key was the ability to use PALM
in any 3D environment by using
multiple cameras to detect the
player.

8. Jon’s Inspirations
● I really liked the modular
buttons of this controller;
however, I felt it was lacking
because of its flat design. It
does not look comfortable
to use.
● I think a modular controller
with a more ergonomic
design would be great!
● I wanted a controller for
one handed use and to fit
comfortably in a person's
hand.

9. Design Process

10. Design Method
Conceptual Design:
● The top of the controller needs to be
smooth and the buttons need to be
accessible by either hand.
● Movement in most games is done by
using an analog stick. To have one on
a single-handed controller, it would
have to be modular so it can be used
on either side.
● To stabilize the controller while
sitting on the couch or a chair, the
controller would need to be secured
in some way.
● The controller needs enough buttons
so that it will be consistent with
standard platform controllers.
● A USB cord is a universal option to
connect to different platforms.

13. Design Assumptions
●The controller should be secured by some method
so it doesn’t require a flat surface (ease of use)
●The analog stick should be modular so it can be
moved to the left or right side of the controller
depending on which hand the player is using
●The controller should contain both buttons and
bumpers to add functionality for complex
controller games
●All the buttons and bumpers need to be
symmetrical so either hand can use them the same
way

14. Button Mapping for Call of Duty
Call of Duty is a first-person shooter

You have various weapons at your
disposal such as gun, grenades, knives
and you can call in tactical aids such as
UAV missile strikes or attack helicopter

20. Play Test Summary
In order to determine the feasibility of
our design we conducted a playtest with an
expert gamer named Ryan. Ryan is a
Sophomore in high school and has been
playing video games since he was four. He
has experience using all types of controllers
for various platforms including:
● PC
● Xbox Original/360/One
● Playstation 1, 2 & 3
● Nintendo
NES/SNES/Wii/WiiU/Gameboy
Advanced
● Smart Phone
The playtest lasted approximately 30
minutes. During the playtest, Ryan was asked
about his initial reactions, the general design
of the controller, its use using only the left or
right hand, and its use in various game genres.

21. Play Test Results /
User Opinions
● His initial reaction to the controller: “It’s pretty
awesome”
● “It would take a little getting used to, but once a player
is used to it, it would be easy. Simple and complex.”
● “The controller could have a button by (in front and
above) the side analog stick for more options.”
● When asked about the side analog stick: “The side
analog stick isn’t weird at all. It’s basically the same as
a normal controller.”
● When asked about its use with a side scroller game:
“For Mario or Sonic, it would be weird to move the
analog stick up to move right instead of right when a
top analog stick, but it would be easy to get used to.”

22. Play Test Results /
User Opinions (cont.)
● When asked about its use with a first person shooter
(FPS): “For Call of Duty, if you could program the buttons,
it would be real easy. The top left bumper could be shoot,
the top middle button would change weapons, the top
middle bumper would be aim. X & Y aren’t really used
that much. The analog stick should have a push button
though like other controllers (like the Xbox One analog
sticks)
● When asked about the overall usability of the ODIN: “The
design is great and it could be easily patentable.”

23. Post Mortem
What Worked What Didn’t
● Work load was distributed
unevenly throughout the
team.
● Rarely had entire team
present at meetings due to
schedule conflicts.
● Example template
presentation had little to do
with current topic, which left
layout questions unanswered.
● Combining the core concepts
of each team member’s week
one designs.
● Having a physical prototype to
run playtests and gain useful
feedback.
● Meeting early on in the week to
decide the game controller
design.

24. Post Mortem (cont.)
What The Team Would Change
● With this being an unorthodox project
with restrictions, more time to better
understand what was needed in a one-
handed controller would have been
helpful.
● The ability to have more hands-on
testing with physical prototypes and play
testers who actually fit the project
demographic.
● Have a solid work schedule and meet
deadlines.
