4. Some Context…
• Work done in collaboration with IGDA Accessibility
SIG for Constance Steinkuehler, former Senior Policy
Analyst at the Office of Science and Technology Policy
in the Executive Office of the U.S. President.
• Heavily inspired by WC3/WCAG and IGDA
• 10+ years of application and web
development experience.
5. Someone You Should Know…
IGDA (International Game Developers Association)
Game Accessibility Special Interest Group

• Game Accessibility Top 10
• Methods for Providing Accessibility
• How Many Need It?
• Etc.
6. What Type of Applications Are We
Talking About…
Visually Dynamic and Rich User Experiences
on Mobile Platforms.
7. What is Accessibility…?
The ability to fully experience
an application even when
functioning under limiting
conditions.
8. Possible Limiting Conditions
Vision
• Vision Loss (e.g. mild,moderate, severe, blindness)
• Color Blindness
• Visual motor impairment (e.g. visual tracking, diplopia)
• Visual field loss
9. Motor (e.g. arms, hands, trunk, legs)
• Motor control impairment (e.g. coordination,
aiming, response speed)
• Muscle weakness (e.g. paralysis, paresis)
• Muscle Tone (e.g. rigidity, spasticity,
hypo/hypertonicity, tremor)
• Balance (e.g. vestibular, visual, proprioceptive, )
• Range of Motion limitation
11. Hearing
• Hearing Loss (e.g. mild, moderate, severe, deafness)
Vocal & Communication (i.e. speech)
• Speech disorder (e.g. articulation, fluency, voice)
• Language (e.g. form, content, function)
• Muteness
12. Type Number %
Some Numbers… Visual – Severe 1,768,000 0.8

13. Can we be all things to all people…
No, but it’s a nice goal to strive for.
14. So Why We Should Care?
• User Satisfaction
• Reach Greater Audience
• Address Government Regulations
• Provide New Skill Building Opportunities
15. Practically speaking…
• Project Requirements
• Budget and Resource Considerations
• Platform Limitations
• Demographic Considerations
• Etc.
16. Current State…(Games)
Vision - Even the simplest issues (such as font size and contrast) are rarely
considered, resulting in significant issues for older players in particular.
Hearing - Subtitling/captioning is relatively commonplace, however the implementation is
highly inconsistent and usually patchy and poorly executed.
Motor – New input devices, control schemes, and mechanics has contributed to significant
growth.
Cognitive - Although many therapeutic titles exist for profound cognitive
impairment, commercial considerations are rare.
Vocal & Communication - Speech is now beginning to be included as an input method as
well as simply communicating with other players on select titles.
17.
18. • Great for Interactive Apps
• Low to Mid-Cost
• Touch Screen Accessibility
• Many (cheap) Apps
• Convenient
• Unique Development
• (often) Special Distribution
• Noisy Input
19. Screen Readers Possible, but…
Unity 3D does not support Screen Readers!
Puts everything on developer which is a major
challenge and demand on resources.
20.
21. You will need to make compromises…
• What are their interests?
• What limitations could they have?
• What will make your audience happy?
22. • Adolescent and young males with SCI
• 16 to 24 year old
• Racial and ethnic minority backgrounds
• Gaming Experience
• Expectations
• Devices (which ones they own and play)
• How often they play
23.
24.
25. Inspiration
• South Park
• Adult Swim
• Call of Duty
• Assassin’s Creed
• Uncharted
• Ratchet and Clank
• Mario
• Zelda
• Deathspank
• Fallout 3
• Hot Shots
• Naked Gun
26. 1. Manual Dexterity
• Includes full control of one or more hands to severely limited movement of
fingers or the need for peripheral devices such as mouthsticks.
• Poor articulation of the fingers often leads to knuckles dragging or fingers
accidentally resting on the device which creates multiple unintentional “taps”.
2. Varying Touch Speed & Accuracy
• Motor impairment often leads to lack of control over pressure sensitivity,
speed, and accuracy due to muscle weakness and involuntary movements.
27. 3. Limited Range of Motion
• Due to muscle atrophy or direct neuropathy an individual’s range of
movements may be limited requiring devices to be placed in strategic spots
(e.g. resting on thigh) or mounts. For those affected this often prevents access
to the full screen.
4. Spasms and Involuntary Movements
• For those affected, involuntary movements big and small can lead to accidental
taps, interrupted swipes, and lack of accuracy.
28.
29. Double taps often lead to accidental clicks
and false-positives due to spasms, multiple
fingers/knuckles on the device, or lack of
force when interacting.
Relying on single taps, swipes, and context
sensitive menus
Requires additional development and
design considerations to juggle the many
interactions players have come to expect.
30. Response time, accuracy and player abilities can
vary, which makes it difficult. (The experience is
too hard or too easy)
Focusing on cerebral/thinking challenges can
lower frustration and shift emphasis away from
twitch reflex.
Risk of being too easy, difficult to fit certain
genres, doesn’t satisfy “twitch junkies”
31. • Some can’t use both hands
• Dual joysticks need to go
• Difficult to juggle multiple actions
• Requires extra care with design
• Often needs special code (ex. Auto-aim)
32. Those with limited motor function often struggle with long precise
gestures due to spasms, placement of the device on their thigh or in a
mount, and a general range of motion limitations.
Quick swipes are easier for individuals to execute and thus leads to
greater enjoyment.

36.
37.
38. Address health and social
situations for those with SCI.
Built around established
conventions found in games.
If the game is “FUN” they
will keep playing giving us
more opportunities for
reaching them.
39. Player is confronted with real considerations
(pressure releases, day planning, bowel/bladder, etc. )
But need to earn cash, fight animal minions,
save the world
Action / Adventure / RPG

45.
46. Tap where want to go in
environment and character goes
there
Pros
• Very accessible
• Passes all the guidelines
Cons
• occasionally frustrating and dull
• less direct control over player
• can’t control speed
47. Player drags his finger along the screen
The character is locked to the touch point.
Pros:
• Allows for fine control of the character.
• Easy to implement and cheap
48. Cons:
• Requires long gestures and constant
interactions.
• More reflex than cerebral
• Player must path around obstacles
• Device gets noisy input
49. Scrollbars on either side of the screen control
the player’s “wheels” independently.
Pros:
• Good connection with character
• Mimics real-world wheelchair
• Can do fancy maneuvers
• Small modification can work for mouth sticks
Cons:
• High reflex requirement
• Hard to juggle multiple activities
50. Virtual Trackball over screen. Swipe in direction
player should go. Speed and length of swipe
affects speed of player.
Pros:
• Good connection with character
• Can build up momentum
• Mimics real-world wheelchair dynamics
• Can do some fancy maneuvers
• Works for mouth sticks
Cons:
• Some reflex requirement
• Susceptible to multi-touch woes
Editor's Notes
This project in it’s simplest form is aimed at creating a fun and engaging game that addresses many of the health and social situations for those with a Spinal Cord Injury.The game is built around common conventions proven in the game industry and uses any method suitable for a given situation such as action, adventure, sports, and puzzle solving with a strong emphasis on off-beat (and sometimes crude) humor to deliver the messages of the game.

Even though the game has elements of puzzle solving, adventure, action, sports, shooting, and driving; at it’s core it is an Action-Adventure-RPG game with character development being a significant part of the experience. The player character for the game is a recent SCI patient who needs to adapt to their new abilities and the world around them. As a SCI individual the player is confronted with real considerations of someone with a SCI such as pressure releases, day and meal planning, and managing assistants/friends. The player must manage the above while trying to earn cash for new gear, fight legions of animal minions, and figure out a secret plot of world domination.
Physicians, OT/PT, assistants, zombies
Against Dr. Schrync and his hordes of animal minions.
