2. Abstract
In these slides we will dive into what inspired each person on the team. They
will explain some of their own key features to their personal design and the way
they choose to do so. We will then explore the design that the team has
created together. Each team member will explain what they pulled from their
own design and how they implemented into the design that you see. We will
wrap things up with our schematics of the teams controller and what games
can be utilized for our controller, with our prototype and game test that we have
conducted.
3. Introduction and Design Purpose
We are designing a human-computer interface device more commonly known
as (HCI); our design is a controller for people with physical disabilities that only
have the use of one hand. Our objective is to make the best controller possible
for one handed use. We aim to have an easy to master and comfortable
controller for these types of gamers. Our presentation is going to show a clean
prototype and some important information on our product. We have also shown
schematics for the button layout and the design method behind our innovative
design. Lastly we have proof of our controllers value and use by capturing
pictures of extensive playtesting session that were performed to guarantee our
controllers usability.
4. Inspiration
The inspiration of placing a modular button mapping design is to give the player the option to use one-
hand whether it’s their left or right hand. Modular features make this controller flexible for the
handicapped player and customizable for the average player. “Address the flexibility to accommodate
all players, so making the core button scheme of (Triangle, Square, Circle, X) modular will allow the
player to adjust for left-handed or right-handed gameplay (Stewart, 2015).” In our design as a team
we put this flexibility on all the buttons, allowing for full customization; making the controller appealing
to not only one-handed players but also your standard two-handed player.

5. Inspiration cont.
My main inspiration came from both the Razor Naga mouse (Razer, Aug. 2009) and Razor Tartarus (Razer, Aug. 2013);
while the controllers were designed for the PC there are key features on it that I believe are very vital to a person who
plays games with only one hand that can easily be moved to a controller on the PlayStation 4. The most important
feature for me is how the controllers are shaped to fit better with our hands. This allows for better motions with our
fingers and less strain on our arm because it is natural to the way we already play games and how our physical body is
shaped. “Having movement controlled with the thumb is important as it is already what most current day controllers have
trained players to use, so it will be much more natural.”(Brandon Pounds, Week 1: Controller Design Discussion). These
two products also have a very rare shape that helps support the human hand, meaning that the size is much larger and
feels much more natural to control.

6. Inspiration cont.
The inspiration for my design aspect that has been incorporated into the team’s
controller design comes from the simple yet effective usability of Batman’s tools
in the video game Batman Arkham Asylum. When analyzing the tools that the
caped crusader uses one will see that his tools have an ergonomic control
layout most of the time placing a button under all of Batman’s fingers so he can
use the device’s multiple functions with ease. “The design of the controller uses
every finger to work the buttons allowing the design team to make the controller
compact and easy to use with one hand” (Austin Steyer, Week 1: Controller
Design Discussion).
- Austin Steyer
7. Inspiration cont.
I was inspired by the PS4 controller and gaming mice. I know
that we were not able to use a mouse, however I think mice are
very easy to use for a single hand. I wanted to take something
that was inspired by a mouse that had multiple hotkeys but for
PS4. I found multiple sites that stated why mice worked better
than controllers. Quoted from smi1ey off of tay.kinja.com “You
have more control over your mouse fidelity (tracking, weight,
sensitivity, etc) via software and hardware features. Most PC
games allow for fully customizing keyboard and mouse button
bindings, while this often isn't the case for controllers.”(smil1ey,
Ph18). When I designed my prototype I wanted to use not only
the controller but integrate it with the Project Morpheus
headset. I dove deep into the how Sony designed the controller
and how many working prototypes did they have. In my
research I found that Sony worked with multiple companies to
create a better gaming controller not only for players but to
designers as well. In this attempt I used the form of a mouse,
combined with having the keys in proximity to your primary
fingers.

8. Inspiration cont.
Well my inspiration came from my own mind. I sat down and I Just looked at my hand and tried to think of a
way to make a controller fit comfortably. After a while of thinking I put my cellphone down and tried some
ideas. I later came up with my original design, other than my cell phone’s shape and the buttons from the
Playstation 4 controller, the inspiration came from my mind. “While the Nintendo gave you a single analogue
stick to play with on its quirky trident controller in 1996, a year later, Sony launched the Dual Analog Controller
as a PlayStation peripheral. Ape Escape launched in 1999, becoming the first game designed specifically for two
analogue sticks, and we’ve been using the same control paradigm ever since.” The Galaxy S6 Edge's curved
screen helped me make the idea for my trigger buttons being on the bottom slightly.
- Justin Lelos
9. Design Method
Our team’s design methodology was pretty standard we went through each of
our first week controller designs and picked out what seemed to be the most
important and or most beneficial to the controller. We then shaped our current
design around these key features to make the best controller possible. As you
can see in figure one we attempted to give the controller a “natural feeling”
shape, close to the shape of a mouse for comfortability since there are a lot of
studies on the benefits of the mouse shape. In figure two we took the idea of
having all the buttons in close proximity for quick button mashing and
accessibility. Figure three shows that either hand can be used which gave us
the basis idea for having modules in our controller. Figure four shows that all
fingers can be used simultaneously at anytime on the controller for ease of use.
Lastly figure five shows two analogs which we decided to use on our final
design for easier directional control of the player and camera.
16. Design Assumptions
There are several ways to make games accessible to those with physical disabilities, one way is to
design games intended to be accessible for them also known as “one-switch games.” The other way is
to use special hardware, which makes mainstream video games accessible to physically disabled
gamers. I decided to use the modular approach with my design feature because I wanted this
controller to work for all sorts of games. If the gamer likes sports games, they can arrange the
controller to help them move with the player better and do special moves quicker. If the gamer like’s
first person shooters, then they can move the triggers and analog sticks into a position that makes it
comfortable to shoot and look around seamlessly. And even if the gamer is into role-playing games,
the gamer can change the button mapping to fit the way they play their character. Having a modular
feature adds relevance to the controller’s flexibility for every type of gamer. That way games that are
generally designed and mainstreamed can be enjoyed by persons with physical disabilities with ease.
- Anthony Stewart
17. Design Assumptions cont.
The design for the controller is to have a similar shape of a mouse yet larger, and have the controller be in proportion to
the average human hand; so the user has the most comfort and control over all the features of our controller. A
traditional mouse it is too small to fit the shape and size of the human hand, when the object is too small people will grip
or hover their fingers over buttons which can cause a lot of tension and strain not only in your hand, but your wrist and
entire arm as well. This creates a muscle overload and in short will cause many problems for both your nerves and
muscles leading from your hand up to your neck. “A conventional mouse instigates gripping and pinching next to
hovering of the fingers above the switch buttons. Based on in vivo tests during field research, it is assumed muscle
spasms in the deep neck muscles may occur” “Exertion of (unnecessary) static forces like gripping, pinching and
hovering (extensor loads) result in muscles acting continuously.” (van Zwieten,Schmidt, Helder, Lippens, Zoubova,
Zinkovsky, p. 02, para. 06, 2011) So in order to prevent this problem the controller must be shaped based on the
natural position and contour of both the human hand and arm. A mouse is easiest to use with only one hand, which is
why it is important to understand the setbacks of a conventional mouse when creating a controller that has a similar
shape to a mouse. Having a person use a controller that is natural to their physical body will eliminate many of the
physical issues that can occur. “According to us such effects can be avoided by means of providing fitting support, thus
preventing the mentioned muscle overload.” (van Zwieten,Schmidt, Helder, Lippens, Zoubova, Zinkovsky, p. 03, para.
03, 2011) Allowing the controller to remain stationary will also provide less stress on the wrist and again prevent any
physical problems. This is why the controller is designed to fit the shape and size of the human hand as well as remain
stationary on a flat surface.
- Brandon Pounds
18. Design Assumptions cont.
Our design for the controller is very simple. We wanted something that did not require you to use your legs or any other body part.
We really looked deep into how the PS4 controller’s schematic is laid out and how the players uses it. Having the thumb be your
main point of movement and placed on the side, it allows the player to grip the controller with very little strained to the wrist or arm.
This is because when laying your hand flat on your thumb sits on its side. We also understand that some fingers are shorter than
others so having the keys at a slight angle makes the controller feel natural and easy to use. I found a study that showed there is a
great split between users using controllers compared to using a mouse. But in this study I also found that a majority of the people
use both mouse and controllers or that they would like to use both. The article from tay.kinja.com by smi1ey shows this.
· “37% of Kotaku readers prefer to use a mouse and keyboard if possible.
· 40% of Kotaku readers prefer use a controller if possible.
· 23% of Kotaku readers use both about the same.
· 48% of Kotaku readers are willing to use both as needed/preferred.
(Smi1ey, PH3)”
This shows that by design this type of controller we could not only design for single arm players, but to players that prefer the use of
a controller or a mouse. We have created this controller to fit the design of a mouse that is accurate to your hand and the way your
fingers are oriented naturally.
- Aaron Christian
19. Design Assumptions cont.
My individual design assumption from week one was having two analog sticks. I
was originally thinking about the one but I found it would be difficult to play
many games with only one analog. So I stuck with the classic two analog sticks
based off of the PlayStation 4 controller. The other reason I chose two is
because when I was testing my other designs I always felt that I was missing
something and it was the second analog. After many different types of prop
types I found placing them close together for the thumb and index or index and
ring finger was the best control options. The only way I could see myself
successfully using a controller would be my dual analogs.
- Justin Lelos
20. Design Assumptions cont.
My contribution for the controller was the utilization of all of the digits on one
hand. By using more fingers for the controls and placing the buttons in a natural
arch the player has a faster reaction time when moving from one button to
another. With a simple and easy to use default button layout our controller is
easy to learn. That being said the modular system added by another designer
allows players to move the buttons to a more comfortable layout for individual
use.
- Austin Steyer
21. Control Mapping
Battlefield is a first person shooter that a lot
of players play and enjoy. We have made
sure that we have designed the controller
to fit the gamer’s needs to be able to play
not only Battlefield, but all first person
shooters. Our schematic shows how easy
and comfortable it is to shoot while looking
down sights, using the Aim and Shoot
buttons (L2,R2). We have also made it
easy for players to reload weapons( ),
change weapons( ), and even use the
knife feature(R3). We have made sure that
all controls are applied for any type control
layout that the player prefers.
22. Control Mapping
Little Big Planet is a staple game for
the PlayStation in its entirety. From
the first game of the Franchise to the
newest it has continued to captivate
all players regardless of their game
preferences. This is why we are
using it as a key scheme for our
controller. Most of the controls are
used by the same buttons. The O
button, X button, button, button
will be operated by the players
middle or ring finger. The same will
be used for both trigger buttons and
the R1 and L1 buttons. Players will
use their index finger to control the
right analog stick to aim and the
directional pad for the expressions.
Players will use their thumb to move
their character with the left analog
stick.
23. Control Mapping
FIFA is a fast-paced game
that requires response and
precision in button
interaction. This button
mapping allows the player
to use middle finger and
ring finger to reach all shoot
and pass buttons while still
maneuvering with the ease
using the thumb stick.

Thought on Controler:
Subject believed with minimal practice that the controller would be natural and
easy to use. Subject confessed that he was worried as to whether or not the
controller would stand up to an inclusive and active game such as a first person
shooter due to the default location of the action buttons ( Triangle, Square,
Circle, Cross.) Subject believed that the modular nature of the controller would
fix these problems.
26. Post Mortem
What happened correctly for our design process would be that we had multiple
designs then built on them and created the best combination between them all. We
also had great synergy and were able to work together to maximum capacity.
What happened incorrectly is that we got to in depth about how the controller would
actually function using codes past the prototype design expectations.
What we would do differently would be to focus on specifics of the assignment
without getting too into our project. The team was very passionate which isn't
necessarily bad but we should stick to the prototyping piece instead of final design.
Designing a controller for only one hand is both complex and takes a lot of
forethought in how to use the human hand to its full extent without hindering the
player.
