Impact That Speaks for Itself
We conducted three rounds of usability testing including A/B tests, think-aloud sessions, and SUS surveys to evaluate how users experience the app.
"Great work! The gesture you designed is brilliant, it feels like you are actually opening a door. The implementation of the prototype is excellent."
"Gesture-based entry and visitor access with integration of Apple/Google Wallet is an excellent idea. The interaction and security protocols are thoughtful and effective."
"Great work! The UI is stellar, and in terms of user experience, it’s incredible."
"The gesture is so cool. Glad you guys didn’t just make a Figma prototype and actually developed the app. Please bring this to Universities as student access cards!"

Reimagining Mobile Access: Gesture-Driven Entry for Smart Security
Overview
We partnered with Johnson Controls to design a mobile-first access control system that replaces keycards with secure, gesture-driven smartphone access.
The solution features intuitive actions like tap, twist, and swipe to unlock doors, along with built-in visitor management for seamless check-ins, making workplace access faster, smarter, and more secure.

Challenge
How might we create a mobile access control system that is secure and intuitive for managing the physical access across work environments?
Johnson Controls offers cutting-edge building technology solutions across industries like government and corporate offices, ensuring safer and smarter spaces worldwide. As part of their vision to expand seamless and secure access beyond offices to gated communities and other facilities, they sought a better, more user-friendly way for people to manage entry. Our team stepped in to explore and design a mobile access control system designed to meet this evolving need.

What Users Struggled With
User interviews revealed the challenges that were faced by the users, needing improvement in mobile access control solutions.
"Over time, my keycards and fobs just stop working reliably. Sometimes the door won’t even scan my card."
“Visitors have to rely on me as there aren’t clear instructions at the entrance. It’s annoying having to help every time.”
“I’m always misplacing my keycard, which means calling security and waiting for him to let me in."
“I like the mobile app, but if my phone dies or Bluetooth fails, I have no way to get in. That’s why I still carry a physical key.”

Breakdown Of the Problem
1.
Physical keycards and fobs degrade over time, causing unreliable access.
2.
Lack of clear instructions for visitors forces residents to assist constantly.
3.
Misplaced keycards and phone dependency create delays and inconvenience.
4.
Mobile app and Bluetooth solutions are unreliable, leading to reliance on physical keys.
Research Process
Business Strategy
Market Opportunity Analysis
We studied the building technologies and smart systems market, analyzed industry trends, customer segments, and competitor presence to identify the total, serviceable, and obtainable market opportunities for Johnson Controls.

Efficient Visitor Management
02
Role-based door access
03
Offline / backup functionality
04
Advanced customization
Understanding the User
User Analysis
We conducted 14+ user and expert interviews, surveys, and a field visit to understand needs and expectations. Insights from this research helped us create our persona, Allie.
User Journey
Based on our user interviews, we created a journey map for Allie, our persona, an employee unlocking her office door and managing visitor access. We found that while basic access was straightforward, visitor access was the task most users struggled with, often leading to confusion and frustration. This analysis helped us identify opportunities to simplify the process and improve the overall experience.
Task Analysis
After understanding how users go through the process and creating the user journey, we collaborated with the Johnson Controls tech and engineering team to develop a task analysis for each step, highlighting what’s important to integrate into the app for a smoother, more efficient experience.

All Sites, One App
Effortlessly manage multiple locations from a single dashboard.
Mapping Out the Ecosystem
IOT Architecture
We collaborated with engineers to understand the technical feasibility of our design concepts and how they could translate into a functional door access system.
Mid-Fi Wireframes
After exploring early concepts through sketches, we moved into mid-fidelity wireframes to establish a solid foundation for the app. Working closely with the tech and engineering teams, we defined the core screens for door access and visitor management, ensuring the structure was clear and technically feasible.
Core System Features
Onboarding
The onboarding process provides secure, personalized access. Admins set role-based permissions, and users authenticate via email, create a passcode, and enable Face ID for quick, contactless entry—ensuring both convenience and strong security
It begins by adding your organization/company-issued access card into your Apple/Google wallet - the first step to seamless door access.
A simple twist gesture activates door unlocking to your nearby door through built-in motion sensors.
Alternatively, users can swipe the unlock button to unlock nearby doors, receiving subtle sound and haptic feedback once access is granted.
Navigate to the Doors page to search for specific doors, view nearby ones within range, or quickly access your favorites.
Gesture Control In Action
Twist to Unlock
The system recognizes the user’s Twist Gesture via phone sensors and communicates with the smart door reader, instantly unlocking the door.
We developed a working demo that includes both the door reader interface (iPad screen) and the mobile access screen. The screen reflects live access status, demonstrating the full end-to-end functionality.
Visitor Door Access
The user navigates to the Visitor page and enters the visitor’s details. An email invitation is then sent to the visitor to start the verification process and receive their temporary pass.
How the Proposed System Solves the Problems
Inconvenience of Physical Access Cards
Traditional keycards are easily misplaced and require manual replacement. The proposed system uses BLE/NFC technology, allowing users to unlock doors securely through their smartphones, reducing dependency on physical cards.
Inefficient Visitor Check-In
Process
Manual visitor access causes delays and security gaps. This new system enables guests to receive digital passes and check in seamlessly without downloading an app, improving both speed and user experience without any delays.
Limited Visibility and Control Over Access
Users previously lacked real-time awareness before unlocking doors. By integrating live camera previews and multi-site control, the system empowers users to make informed decisions, ensuring greater security and transparency.
