Biker Safety Belt

User Research :

I did 20 face to face structured user interviews and created a survey of 30 people. I created a interview guide to ask all interviewees similar questions. Interviewees included people at the gym, jogging on streets, bikers in the parking lot, members of Virtual reality club and avid Pokemon game players. Questions based upon observations such as interviewees clothing, things, expressions were also asked.


Survey Analysis :

I created a survey which included multiple choice as well as open ended questions for 30 people. The survey has 20 questions but could be completed in 2 minutes. The purpose of the survey was to get insights into what kind of games college students prefer and the role gaming plays in their everyday lives. I observed that checkbox question, the option at the top were selected more often than those at the bottom. People might have been influenced by the order of the question.

The survey on Gaming experience was conducted on Oct 15, 2016 at UC Berkeley and most target population was students. As seen above, most students prefer adventurous and problem solving games. I learnt that many students reduced gaming duration in college as they found it to be a waste of time. Therefore, my team decided to make gaming more enjoyable by giving it a purpose.


Personas :

Based on the insights we got from the user interviews, I designed two user Personas. I designed them to reflect both the perspective of the biker and a car driver as they problem that we were going to solve affected both. The attributes that these people have were derived from the significant quotes that we got from our customers.

Ideation :

Design Strategy

In the ideation stage, I came up with 50 ideas that could solve the safety problem of the biker. Most ideas could be categorized as one of the branches of the mind map. We then sketched out a few of our top ideas to understand their scope and feasibility better.

To narrow down the ideas, we used methods such as Life cycle analysis, needs assessment narrow down the ideas, we used methods such as Life cycle analysis, needs assessment and 2x2 matrix. 1) The life cycle analysis helped use figure out the impact of the materials used on the environment. We realized that disposing the LEDs used would be an issue for the user. 2) The needs assessment was used to prioritize which needs to focus on. We decided to focus on convenience, functionality and physical design. 3) A matrix of gaming frequency and level of gaming interaction allowed use to place the existing user on the map to find our target market segment. Additionally, while picking the idea, the voice of our sponsors and other stakeholders was very important and they wanted a product that had a large customer base.

The design process was very iterative. As a team, we went over and lowly developed many ideas and tested them out. We made design decision and made changes based on our sponsor's needs.


Prototyping :

Our lo-fi prototype was just a conceptual model of our product. We started off with a jacket and added the key functionalities to it.

We later shifted to designing a belt as our research indicated that users wanted a product that was compact and easy to carry. The belt could address other issues such as size adjustment, incorporate backpacks, lower costs, etc. We later tested the belt with bikers to check if the biking inclinations, movement, etc affected the usability of the product.

Our Roadmap was based on the user needs that were prioritized during the interviews. I created user needs based on the my interview transcript and converted needs into the product features. The team then created a plan for future developments.

In future, I wish to develop a more hi-fi working prototype using arduinos and other electronics. I would also want to test my product more to get insights into the usability of the product. The project is in partnership with a team at Stanford University where the team is creating a stretchable and flexible material. Therefore, along they way I would want to use that material to enhance the functionality of my product.


Tradeshow :

This project was a part of a class called Human Centered Design. At the end of the course, I gave a 15 mins presentation of my product to a panel of five judges followed by Q&A. They work was highly appreciated and the positive feedback has motivated me to work further on. Additionally, I got some key insights from the judges that I would like to incorporate in future.


Brief :

Bike safety belt is a wearable device that allows biker to give indications of his directions to the people around him at night to increase safety.

Role :

User Researcher doing interviews, survey analysis, design strategy.

Purpose :

...

Design Process :

Began with one on one interviews, surveys and need finding Designed persona, storyboards, and brainstormed ideas. Carried out user testing with a lo-fi prototype and developed a design strategy.
