Overview

Where Are My Keys? (Again...)

I misplaced my keys (again). It felt like the world was crashing down on me until I found it the next day. Turns out it had slipped out of my pocket during lecture and fell under my chair. After talking to my friends about this incident, I realized a lot of people around me dislike using physical keys. I decided to design a new system that allows for young adults living in apartments to easily unlock their doors.

Interview

Discovering attitudes and behaviors

I interviewed 5 participants (ages 20-27) who live in apartment housing. The purpose of these interviews was to better understand their attitudes and expectations when locking and unlocking their front door.

Insight #1 - Certain keys are difficult to use

Participants believe that metal keys are especially hard to twist and insert, and overtime get more and more difficult to use. Keys are also a hassle to take out and use when a participant's hands are full. One participant even admits that they always leave their front door unlocked to prevent the hassle.

Insight #2 - Keys are easy to misplace

Every participant has locked themself out of their apartment at least once in the past year - some even once a month. Participants recount these moments as extremely stressful, because they often do not know what to do. They also note that fees associated with lock outs and lost keys are very expensive, which is an added stressor.

Insight #3 - Customization is important

Every participant has their keys on a keychain that they have customized to fit their personal style. Some participants attach acrylic anime figurines and others keep tiny plushies on their keychains. Customization also serves a utilitarian purpose by offering visual distinction.

Insight #4 - Security is a concern

4/5 participants value security and want to be certain that their apartment is safe to live in. Some participants take extra precaution such as checking that their front door is locked every night before going to bed.

Insight #5 - Passing around a key

All participants admit that they have passed around their key to their friends, family, significant others, and roommates before for a variety of reasons.

Insight #6 - People enjoy the tapping mechanism

All participants believe that the tap to unlock mechanism is very quick, easy, and satisfying. One participant expressed it as "cool wack-a-doodle time."

Design Question

How might we design a new system that makes it easy for residents in shared living spaces to unlock their doors?

User Persona

Understanding the audience

Based off the user interviews, I created a persona to illustrate the needs, goals, frustrations, and motivations of the users. I then created a journey map to analyze the potential emotions and pain points associated with entering and leaving the apartment.

Information Architecture

Setting up the blue print

Using the user persona and journey map, I brainstormed essential features of the app and mapped out the architectural structure of the app.
