The Objective:

To design a mobile application capable of alerting those who travel on foot to potential hazards on their commute in real time. 

The Method:

I utilized skills including:

  • Client Interviews

  • Potential User Interviews

  • Affinity Mapping

  • Wireframing

Kristina T.

The Process:

I started my first ever design project by falling back on the interviewing skills learned during my undergraduate research project at The College of Wooster. After hearing the problem, I compiled questions to ask the client and from her responses, questions to ask the potential users of such an application.

Example Questions:

  1. Where do you most often run into problems?

  2. What are the most common obstacles you run into?

  3. When would you be using this application?

Compiling Results:

Using my newly learned Affinity Map technique, I was able to neatly organize the results of my interviews into four categories:

  • Why I need the app

  • I will use the app when

  • I wish I had information on these issues

  • I want the app to give me these options

The Problem:

As a pedestrian, I want to know what the best route to take is when keeping to the sidewalks during my commute, avoiding obstacles that may cost time or cause injury.


Utilizing another newly learned skill, I created my first storyboard to help people visualize the transition from problem to solution.

User Testing:

Unfortunately first round testing revealed several weaknesses in the initial design including:

  • Use of the "!" to report obstacles was not obvious

  • Users needed to be able to distinguish between different types of obstacles

  • The app was too time consuming to use, especially the process through which obstacles were reported

Ideas for the Future:

  • Based on the initial user testing it was clear that significant changes were required to increase the app's ease of use while on the move.

  • The app would also benefit from a return to and expansion on the interview and survey phase, allowing me to pull more specific information from a wider demographic of users. 

  • In addition a comparative analysis of similar apps would provide insight into how apps designed to be used on the go simplified their interfaces.

The Solution:

A mobile application that will track and display pertinent pedestrian obstacles in real time while remaining clear and non-distracting.


A lack of familiarity with the concept led me to creating something more akin to a paper prototype. This mistake unfortunately used up too much time and prevented me from getting to make a post user test prototype.
