• For navigation and music selection
• Majority do not support a variety of apps
Rationale for Selection: Customer Needs
• Survey
• Gauged what apps people wanted

Concept Generation
• Primarily Brainstorming
• Drew inspiration from external search and customer needs survey
• Created a large list which we narrowed down to the most efficient,
safe, and practical solution
Concept Selection
• Wanted a system to fully connect the user to the vehicle
• Wanted a safer alternative to manual controls
• Decided on the Integrated Voice Command System
➔ Safe (less distractions)
➔ Easy to use
➔ Customizable user experience
➔ Variety of functions

Interface
A Day in the Life of a User
• Vehicle start-up: system greets, updates, and informs
• During travel:
➔ Voice commands for
◆ Applications
◆ Navigation
◆ Music
◆ Vehicle Systems
◆ Internet Search
◆ Etc.
A Day in the Life of a User
• Fully customizable:
➔ Language
➔ Appearance
➔ Tone (voice)
➔ Start-up settings
➔ Updates
● Can be put into sleep mode
● Alerts for vehicle problems or maintenance
● Vehicle Systems
Life Cycle Assessment
Planning/Design:
• LaborTeams for software/hardware and housing
• 3-5 year design time
• Prototyping- High cost and time variability
Use:
• Maintenance-Software updates via download, hardware fixes at
dealership/mechanic
• Sustainability/Duration-Should last for life of car, updates may not be
supported after warranty is up
Life Cycle Assessment
Recycling:
• Materials• No hazardous materials
• No reuse value
• Cannot be uninstalled and reinstalled
• Cost• Included in car recycling costs
Economic Viability
• Cost: approx. $3,000 (retail mark-up)
• After the car is purchased, the only other cost from the system
would be data service charges
• Could be produced for well under $3000 due to existing
components in the vehicle
• Profitable
• Customer interest and satisfaction
