Software for people - building apps for visually impaired users
Who
Why
When
What
team
company
Polish high-tech software company since 1991
Highly qualified staff – over 450 engineers, IT specialists, architects and developers
70% of revenue from export (USA, Europe, Asia)
6 offices in Poland, one in USA, one in Germany
clients and customers
to create software with social impact
to explore new areas
to build R&D
good business case
statistics
According to the World Health Organization
285 million people are visually impaired worldwide: 39 million are blind and 246 have low vision.
Approximately 11.4 million Americans are blind or visually impaired and one person goes blind every 11 minutes.
There are about 7 million visuall impaired iOS users
launched in 2010
part of building R&D
continued until now
iVirtualEye, POIG 1.4
started with small idea
R&D - using the smartphone as an aid
evolved into toolsuite for visually impaired
More and more ideas from the users and community
strictly ambitious research
pedestrian crossing detection
pedestrian light color detection
detection of approaching objects
pedestrian crossing assistant

Challenges
Target
Difficult to assess the solution

Difficult to run developer tests

Time to test the solution
hermetical environment
Difficult to access users, mailing lists are moderated and closed for commercial.
Best way to make contact - through the person within.
marketing and promotion
Technical
Staying in line with Apple guidelines
Performance
User feedback - vibrations, sound, privacy
Color detection
Working with VoiceOver:
- scarce resources (133 for VoiceOver vs 1711 for TableView on SO)
- interrupts
- redefined gestures in VoiceOver
- reduced number of available gestures, some inaccessible
- some patterns unusable (modal views in Skype)
Apple restrictions
Apple guidelines for applications - interface must be compliant with Apple requirements, no matter that application is for the blind.
real cases - cases that are difficult to figure out/predict
Torch for a blind person ?

• Points management
• Points and routes management
• Weather forecast
• Neighborhood exploration
• Backup and synchronization via Dropbox
• Automatic routes - tracking
Home
Application supporting blind and visually impaired people in everyday life.

Features:
• Bar- and QR codes scanning
• Bar- and QR codes generation for labeling
• Color recognition
• Light detection
• Digital magnifying glass
Magnifier
SeeingAssistant-Magnifier allows to use the phone as magnifying glass.
It is a subset of SeeingAssistant-Home functionality, working as a standalone application.
Light
SeeingAssistant-Light – light detector, which generates a characteristic, continuous sound.
The tone of that sound depends on light intensity.
It is a subset of SeeingAssistant-Home functionality, working as a standalone application.
SeeingAssistant family
Cloud computing
• Unlimited horsepower
• Ease of deployment (SaaS)
• Low costs for the end user
• Power tools
image processing and recognition
OCR
• gas meter reading
• hanged PC screen
public transportation numbers detection
One of the biggest challenges - make visually impaired independent.

How
Hardware
iPhone 3GS, 4, 4S, 5
iOS platform
release process
Software
iPhone 3GS, 4, 4S, 5
standardisation
- Standardized hardware
- Standardized OS
- 93% iPhones and 83% of iPad running iOS 6
accessibility
Available since iPhone 3GS, Apple's screen reader with build in accessible features made iOS the best platform. Android had screen reader called Talkback, which provided only basic abilities.
GPS
Get current location. Location Services uses a combination of cellular, Wi-Fi, and GPS to determine your location.
GLONASS (iPhone 4S or later). Different accuracy from 5m to more than 1000m.
Camera
Used for image processing - color recognition, light detection, magnifying glass, barcodes scanning.
Compass
Used to explore neighborhood.
VoiceOver
Built in IOS screen reader.
beta testers
group of beta testers, both blind and visually impaired, simple delivering application to them by website and e-mail using CI server.
feedback
AppStore releases
Delivering final version of application after tests and feedback.
Continuous Integration
- Monitoring commits and correctness of build
- AdHoc distribution for beta testers
Built in IOS screen reader.
UserVoice
UserVoice access built in application via UserVoice SDK. Standard access via website. Forum with threads and votes.
Voxer
Effective way to quick voice communication with beta testers.
e-mail
Standard e-mail channel.
