HUDNAV
3rd Party Heads Up Display for Driver Safety
HUDNAV
Automobile is the predominant way of transportation in the USA. With a focus on improving driving safety with the aid of technology, this project aims to make advanced navigation features accessible for all cars and all drivers.
Secondary Research
Vehicle Safety & Driver Distraction
According to NHTSA(National Highway Traffic Safety Administration)..
In 2021, 3,522 people were killed and an estimated additional 362,415 people were injured in motor vehicle traffic crashes involving distracted drivers
In 2021, there were 644 nonoccupants (pedestrians, cyclists, and others) killed in distraction-affected trafficcrashes.
In 2019, 9% of the fatal traffic crashes (33,487) are distraction- affected. 14% of the distraction- affected fatalities involves Cell phone usage.

User Interviews
with 4 drivers who drives with navigation systems...
Tobias
Cochran
Cochran
24 yrs old; lives in Houston, Texas; drives at least once per day; uses Google maps on phone with a phone stand
“I had a problem with the first phone mount when it couldn't dropped down low enough so it took up like half of my visibility and block the center of my windshield so that was definitely a problem where l just couldn't see enough out of my car.
Julius
Biberman
Biberman
24 yrs old; student at Rhode lsland School of Design: lives in Providence, Rl; uses Google maps on phone and holds it by hand
“I used to have one (phone stand) but then it broke and then I bought another one and that one also broke. So l don't use them anymore. l just hold it by hand when I'm driving ... or if l have a passenger with me, sometimes Ill have them give me directions, but generally I'll just be holding it myself.

Boyd
Student at Carleton University: 31 yrs old; lives in Ottawa:Use Google maps on phone for navigation; secures phone in cupholder
Yeah,I get distracted for changing songs. Sometimes I'm checking social media. Yeah, I'm not a great.I'm a somewhat distracted driver. won't swipe through lnstagram, but if l get like a notification... Sometimes l don't have to look it up, but sometimes I'm at a light.I'l look at my phone.Which is not good.

Spears
Professor at Rhode lsland School of Design;lives in Providence; uses Apple maps on phone for navigation with apple watch for hectic feedback
“I try not to but I probably look,I probably take my eyes off the road a handful of times during a single drive to adjust the music right or read a text message which l really try not to do, or look at navigation directions.
Data Points
An afinity map was created based on the analyzed data points and users experience from the interviews.
Below are the main themes identified from the affinity map.
Below are the main themes identified from the affinity map.
Driving with Navigation
Frustration
Stress
Multi-tasking with phone
- Texting when driving
- Checking SocialMedia
- Choosing music through phone screen
Direction Lacks Clarity
- Complex Intersections
- No Lane Indication
Distraction Occurs Frequently
- Phone Placement blocks driving field of view
- Removes attention from road to check nav.
- Holds phone by hand for navigation
The road is ever-changing
- Performing Maneuvers
- Encountering traffic and accidents
- Extreme Weather
Define
Problem Discovered:
Drawbacks
of
Traditional Navigation Apps
- Placina the device - Recuires to purchasephone stand/phone mount separatelv
- Distraction- Drivers tends to frequently interact with the phone and multitask due to it placement
- Hard to See- The interface is often out of driver's FOV or the interface blocks drivers view on the road
Problem Statement:
How can we provide distraction-free navigation to enhance driver safety ?
Drawbacks
Realizing that driver's needs are different due to the driving environments,l created two different to tackle detailed user goals.

Stakeholder Research
StakeholderInterviews
In order to explore the industry of navigation, UX, and its relationship with automobile, seven interviews
were conducted with designers, engineers, and mangers who are active in this space..
were conducted with designers, engineers, and mangers who are active in this space..
“We want the drivers to relax, chill and no need to worry about handling the steering wheel and they can always pay more attention to the road."
“You have to take in the consideration that the driver cannot look at the map all the time."
“We were focusing on the users who finds driving in the city stressful.and looking, taking their eyes off the road stressful and following map shard.”
“So what we do in our routing algorithms is to reduce the number of left turns to take. Left turns are very dangerous."
“How do we make sure that drivers know that's a U turn or like you have to actually go around this block? How do we make sure we communicate the right info at the right time is what we are trying to focus here."

Strategy
Project Proposal: A third-partyHeads Up Display device thatdisplay navigation through theprojection of a mobile app
Technology Research
Heads Up Display (HUD)
First being utilized in aerospace, HUD technology uses combiner glass that's both reflective and transparent. This drastically enhances situational awareness by allowing users to view both the outside world and important on-screen information simultaneously, minimizing distractions during critical situation on the road.

Ul for Urban Streets
For Urban Driving, the navigation will showcase the map and the route in a zoomed-in level so the drivers will be able to see the nearby streets as guiding reference for route and location. The turn instruction icon provides guidance for the upcoming maneuver for complex intersections
Ul for Urban Streets
For Highway Driving, the map and the route are more zoomed out to deal with high speed environment.
To fulfill users' needs, the interface features pop ups on the side to warn users about the accidents,weather, or merging, increasing user' s response time for critical situations

High-Fidelity Model
The Final Model was built in Fusion 360 and 3D printed with ABS plastic filament for the highest fidelity. The Assembled device was printed matt black to minimalize visual distraction when in use.
Hinge Mechanism
The hinge mechanism features a swivel-like design with damping so the glass can be adjusted and stays in the desired angle with stability.
Beams
Splitter Glass
Splitter Glass
This projection device utilizebeam splitter glass with 40%transparency and 60%reflection rate,ensuring userssituational awareness andnavigation clarity simultaneity.
Securing the Device
The bottom of the base are attached with double-sided adhesive pads, giving users the flexibility to place it anywhere on the dashboard.
Placing the phone
The front of the device has a cutout so the device can be easily taken out after usage. The inlay of the device features a layer of silicone grip pad ensuring that the phone stays static during the drive
Cutouts for Charging
Considering the fact that navigation often requires the phone screen to be on for extended period of time, the sides of the device features cutouts for charging cable
