UX Case Study
Project done as part of the course CS6755 - HCI Foundations by Dr. Bruce Walker
A detachable interface mounted on a bike handlebar that helps food delivery bikers communicate with customers and restaurants in the delivery process
A dedicated on-boarding app for setting up the dPod device

User Testing & Iteration
In this project, we ideated and designed a setup device for food delivery bikers that enables them to perform the core functions of calling, texting. navigating and updating status for orders while on-the-go. The setup consists of 4 main parts.
The biker's safety is kept paramount in the device's
design and the interaction with the device using the
attached joystick is limited to minimum in order to avoid any safety hazards while riding.
User Research Process
The bikers work as independent contractors and often take on multiple orders on different applications at the same time
Bikers often stopped to check GPS / call customers on the way.
Bikers often spent time waiting at the restaurant for the order to be prepared.
Bikers do not have any workers compensation or healthcare included.
User Group Analysis
Third Party App Employees
Single Restaurant Employees
To consolidate our findings from the research methods, we created an Affinity Diagram to get a visualized picture of the notes generated during the interviews as well as in the literature review session and the competitive analysis report. We wrote our raw and low-level notes
on the yellow stickies, and grouped them with the pink, blue and green stickies to generate major themes and pain points for our users.
Major Themes and Pain Points
Our Affinity Diagram revealed a lot of major themes and pain points about our users that were radically different from the assumptions
that we had made before starting the research. One major theme that occurred during the analysis of the Affinity Map was the issue of lack of effective communication between the biker and the customer as opposed to the previously thought navigation, which was only a secondary concern for most bikers.
Bikers often work in teams and make friends with other bikers.
Love for the Job
Bikers enjoy the adrenaline, freedom and the exercise that their job provides.
Bikers use their personal smartphones and bags for the job and prefer inexpensive equipment.
Do not have clear idea of location and customer preferences before starting.
Receiving the Order
Restaurants have huge waiting times and don't update order status in advance.
Relying on GPS slows down the process. Bike parking and safety is an issue too.
New bikers often take a lot of time to
learn assistive technologies for navigation and communication.
Are often riding on crowded roads to finish orders fast.
Brainstorming Diverging Ideas
After identifying the themes and pain points for our users, we then generated design ideas in a very divergent manner, which implies that
we generated as many ideas as we could. Most of our ideas were targeted towards tackling common themes such as efficiency of the
process and simplicity of the design.
Generating Design Ideas
After listing all the design ideas, we then rated every idea on 2 concepts - Creativity and Practicality (C and P in the image) on a scale of 0 to 5. The average of these 2 scores helped us get our Top 14 Design Ideas.

Designing the Information Architecture and Initial Sketches
We used our takeaways from the themes and pain points to design the structure of the device in two phases - designing the hardware of the
setup and then defining the information architecture.

Designing the Information Architecture
Structure of the dPod Setup
The dPod is designed and conceptualized as a set of four distinct components that work together from the start, when a biker receives the order till the order is finished and the biker updates the order status. The four distinct components in dPod are identified and explained below.
01. dPod Circular Interface
This is the main interaction screen (only has visual interaction; no touch is involved) while riding.This nullifies the need for the user to look down and navigate since the functioning of the joystick is widely intuitive, hence taking the safety point of the biker into consideration.
Pink Foam model of the device
The circular cylinder has a 4 inch diameter and a 1 inch thickness. The user interacts visually with the screen and controls the functioning with the four-directional joystick on the handlebar. The device can detached to ensure safety when the bike is parked on sidewalks as found during the user research process.

2. Four-Directional Joystick
(A typical image)
This device is the primary navigation control for the design. It is a
detachable (to accommodate handedness) flat joystick mounted to the side of the handlebar.
3. Bone Conduction Headphones
(A typical image)
Special type of headphones that sit on/around the ear and allow the wearer to hear their surroundings while listening to the headphones, thus promoting safety of the biker while calling customers.
4. dPod Connect Mobile App
To use the system, the user first opens the dPod Connect application on their phone and connects to the order tracking system. Then, the user can select deliveries to complete in the order. After that, the dPod Connect will automatically send all relevant information such as contact numbers and addresses to the circular screen interface, and the user is ready to get on the road and start the delivery. The application works in dual modes, based on whether the user works for a restaurant or for a third party application that supports multiple restaurants.
