Phase 0: Planning
Mission Statement
Product Description
The ARC of Monroe County has requested a communication board for one of its consumers who has limited
verbal and spelling capabilities. This would replace a paper-based communication book. In the past, the
individual has utilized a commercial electronic communication board that has a fixed membrane keypad with a
variety of changeable overlays. A prototype solution was implemented during the 2006/2007 academic year
that demonstrated the fundamental operation of a battery powered, touch screen, and LCD display based
device. Based on feedback from the customer, the prototype needs to be refined to more closely meet the
actual customer requirements in terms of size, weight, durability, and operational characteristics.
Key Business Goals The primary business goals of this product are to
Improve the quality of life for an individual with speech/spelling disabilities by providing the ability to express
his/herself through a picture based communication boa
Create a product that can be utilized by all individuals with speech and spelling disabilities throughout the city
of Rochester, and possibly the whole state of NY, contributing in a positive way to the community.
Primary Market
The primary market for this beverage container is the ARC of Monroe County
Secondary Market
Secondary markets for this communication board include any individual with speech and/or spelling
disabilities, as well as children between the ages of 3 and 7.
Stakeholders
Stakeholders in the design of our product include the following:
The ultimate consumers
The ARC staff who interacts with the consumers regularly
The families/friends of the consumer
The visitors to any area in which the product is being used

Phase 0: Planning
Resource Requirements
People
EE faculty (RIT)- assist team wit embedded system design, hardware and software, and user
interface design and circuitry.
ME faculty (RIT)- assist team with packaging, materials, and durability design
ISE faculty (RIT)- provide guidance with manufacturing and ergonomics knowledge
ARC Monroe Southwest- provide team with specific customer specifications. Can consult team on
status of product through development phase, providing input regarding efficacy and usability of
product.
Environment
ARC Monroe Southwest: Can observe customer using the communication book (current)
RIT: Space for storage, testing, and construction.
Equipment
RIT: Equipment for assembly and testing of device. Computing tools for hardware and software
development.
Required, a significant amount of this equipment can be found in the Electrical Devices lab. The
team will have access to this lab.
Materials
NSF: Funds to purchase materials to assemble product
RIT library: Reference documents for applicable codes and regulatory agencies
RIT: Materials from last years design team (P07001) such as the end product, BOM’s, and
engineering logbooks- Electrical Devices Lab.
Major materials such as LCD screen, computer software/hardware have relatively short lead times
(2-3 weeks) and will not have to be ordered prior to the start of Senior Design I.

Phase 1: Concept Development
Identify Customer Needs - Interviews
Primary Customer(s)
So far, two interviews have been conducted with the faculty guide Dr Phillips. The overviews
were both very detailed and the primary objectives emphasized were captured.
Lisa Drewski has been contacted via email and an interview for this week will be finalized via
phone on Monday September 24th. An interview guide is documented and the responses will
be recorded in the engineering logbook.
Other Stakeholder(s)
An email was sent to Dr Debartolo regarding a meeting discussing last years project. She has
not yet replied, but hopefully an interview will be conducted this week.
Amy Feekes – She is the caregiver for the end consumer, her phone number and email
address were recently acquired. Ameeting will be hopefully be conducted with her on the same
day the interview with Lisa takes place
Past Senior Design Team(s)
This project is a continuation of a project that was completed last year (P07001).
The team’s webpage on the edge website is currently available, as well as the engineering
logbooks used by the team during senior design I and II from last year.
The team’s final product is available for the team to use (benchmarking analysis, etc)
EDGE™
Phase 1: Concept Development
Identify Customer Needs - Benchmarking
Competitive or Cooperative Solutions
The optimal product that most closely meets customer requirements is the Dynavox 4
Currently, a paper based communication book is used in which the user must scroll through dozens of pages
in order to locate the appropriate symbol. The symbols appear upside down if the person they are
communicating with is standing in front of them.
Examples I would like to bring to a benchmarking session include the end product produced by last year’s
senior design team, printouts containing detailed information regarding the Macaw device (considered
inadequate) and the Dynavox 4 (considered ideal)
Everyone will examine the three products and record any observations/recommendations of what they like
and dislike, and what should be implemented in our product.
Last years device is present in the Electrical Devices lab in the Electrical Engineering department, the other
two products have been researched online and print outs containing prices and specifications have been
obtained.

Future Plan
Where do you go from here?
From this point, I look forward to meeting with Lisa and Amy this
week. This will result in a finalization of the desired end
product as well as a re-evaluation of the customer needs.
Once this is complete, a second draft of the concept
development phase will be able to be done. Other than that,
an effort can be made towards searching for possible
candidates to be on my team for Senior Design I and II.
