Project Summary

The 911 Simulator System will be a tool used by fire departments and other emergency responders to routinely provide 911 training for residents who may not be familiar with how to make emergency calls using the 911 emergency response systems. This training is often provided to school children starting from the 1st grade. Other groups who will benefit from this training include immigrants who cannot communicate in English or Spanish, immigrants from countries with different 911 systems, or individuals who are not familiar with calling for help. A system used for this type of training currently exists, but does not provide the desired functionality.

The goal of this project is to develop a simulator that is portable, accessible for deaf and hard-of-hearing individuals through text access and is easy to use in a classroom setting to teach the use of the 911 emergency response system. The expected result is a functional prototype that can be used by emergency responders in the 911 emergency response class.

Stakeholders

• Trainer
• 911 Operator
• Homeowner
• Volunteer
• Audience
• MSD Program

Project Goals and Key Deliverables

• Portable
• Audience-friendly
• Include texting for Deaf and Hard of Hearing community
• Low cost and easy to maintain and replace

Team Vision for Product Definition Phase

• Work with customer on needs from the community
• Make a device that is accessible to all new residents and students

Constraints

• The 911 Training Simulator ("The System") must operate from a standard 15A 120v receptacle.
• The System must not be able to actually contact 911. In other words, it must not be capable of initiating real cellular calls.
• The System must be easily transportable by a single person.
• Input devices must include every commonly used type of phone. (This includes cellular flip phones, smart phones, and landline phones.)

Team Plans for next 3-week phase (System-Level Design):

Desired deliverables at end of System-Level Design Phase:

• Plan for how all devices will interact via central processing
• System design that details breakdown of audio and video handling
• Breakdown of how processing will be designed to evenly distribute workload among team members

Individual Plans for next 3-week phase (System-Level Design):

Elijah:

• Analyze existing 911 Simulator (current pros/cons, features, etc.)
• Maintain effective communication with Customer
• Confirm requirement with customer (do mobile phones need to connect wirelessly?)
• Explore options for wireless communication options (other than cellular) for flip phone
• Determine required user interface (text, call) for flip phone
• Determine required capabilities of flip phone (wired/wireless, display, keypad, etc.)
• Work with team to determine possibility of designing simple training phones instead of utilizing/modifying existing phones.
• Select final flip phone model
• Work with Dania and Grace to map requirements to design functionality

Dania:

• Explore options for wireless communication options (other than cellular) for smartphone
• Determine required user interfaces for smartphone (audio, text, etc.)
• Determine required capabilities of smartphone (battery, wireless, OS, etc.)
• Select final smartphone model
• Coordinate identification of skills for each team member

Alex:

• Coordinate with Elijah and Dania during process of determining requirements and selecting phones
• Work with team to explore possibility of designing a training phone instead of utilizing an existing flip phone
• Work with Zhengguo to select smartphone interface technology
• Work with Zhengguo to select flip phone interface technology
• Work with Zhengguo to determine the computing hardware to use for the simulator (one combined unit, separate audio and video, etc.)
• Oversee consolidation of system-level design

Zhengguo:

• Explore options for disabling real 911 capabilities in existing smartphones and flip phones
• Work with Alex to select smartphone interface technology
• Work with Alex to select flip phone interface technology
• Determine required I/O for simulator's main unit (AV output, input for trainer, etc.)
• Work with Alex to map design functionality to hardware selected

Grace:

• Determine required interface for 911 operator (trainer)... Keyboard, phone, display, etc.
• Select peripherals for operator's workstation
• Select landline phone for students to use
• Coordinate with Alex and Zhengguo in selection of final hardware to facilitate design of final enclosure for simulator
• Work with Dania and Elijah to map requirements to design functionality
