Bridging the communication gap
Vision statement
To become the world leader in sign language translation products
About Us
● four engineering students (4th year) from SFU
– Ganesh Swami (President and CEO)
– David Brayden (VP, R&D)
– Phoenix Yuan (COO)
– Kjell Eggen (CTO)
Agenda
● Problem overview● Voiceture solution overview● Design Implementation● Market analysis● Business model● Product demonstration
Problem• communication between a deaf/mute person and an English speaking person
• deaf and mute people depend on translators
Solution
● Integrated hardware and software solution
● Innovative algorithms
● Economical● Portable
System OverviewUser
Data Input Glove
Sensor Electronics
Computer Analysis System
User Interface
Key Features● Adaptive● Platform portable● Requires minimal
setup
System Implementation
Sensor PCB
Main Software flow
Technology
● bend sensors– Strain gauge– One per finger
detect finger position
– economical– reliable– Low profile
Technology
● sophisticated pattern recognition algorithm
● gaussian statistics
● adapts to the users specific gestures
● 7D statistical sample space
Detection AlgorithmStart
Create an index(0 = A, 1 = B, etc):
i = 0
Calculate the 7-D distance (d) from
letterData[i]
Increment i
Subtract a factor from the letter bin:
letterCounter[i] =- factor
Is the distance less than radius[i]
Calculate a Gaussian factor:
gFactor = exp( d^2 / (2 * radius[i]^2) )
Add the Gaussian factor to the letter bin:
letterCounter += gFactor
Is the letter bin enough to be output:
letterCounter > Threshold?
Are all the letters scanned:i = 26?
Output the letter:Result = letter[i]
Output nothing:Result = “noMatch”
Exit

Business model
● Product– Marketable product for sign language
translation– One time non-recurring cost ($400-$500)
● technology licensing– Customized solutions to meet specific
customer needs (i.e. teaching institutions)
Market position
● Segmentation– teaching aid– replaces human
translator (up to $70USD/hr!)
● Competition– image recognition
(not including English)
Languages in the US

Project Cost
Timeline
Prototype Status● 16 / 24 letters with greater than ~80% accuracy● remaining letters working with less accuracy
● resolution of the glove not to specifications● thumb sensor not sufficient
