Bravida Card Reader
Interface Design: Universal Access
February 2010
3 weeks
Problem
Bravida has been selling access control and security systems in the Scandinavian market for the past ten years. They wanted to update their existing card reader to work through touch free handling for universal types of users.

Objective
Design a universal access card reader that can be implemented within the next few years.

Solution
Identifying key problem scenarios that main personas encountered help guide the final solution of the project. Through smart RFID, the outcome is a system that eliminates the swiping mechanism for hands-free identification. The device identifies if the user has a disability notification, administrative capabilities, screen level of tilt, or language preference. The dynamic keypad provides customization for placement of various icons or higher level of security capabilities.

My roles: leading team meetings and brainstorming sessions; conducting user interviews and testing; and user interface design.

Collaborators: Mohammad Bahadori and Joakim Nordlund

User Interviews
Umea University is Bravida’s largest client in Sweden, thus we interviewed students who had daily interaction with the card readers to gain a better understanding of the design problems. Users were observed using the existing magnetic card swipe system and were asked how they felt about the features and their ideal access card reading system.
Ideation and Sketch Models
As a result from ideation, we produced four different low-fi card reader sketch models for user testing. Each model was evaluated based on:

Intuitiveness
Privacy
Speed
Feedback
User Test
Evaluating our test results and research led us to refine our ideas. Users evaluated the following: Preferred RFID item (card or item for key chain) Display graphics Button’s shape, size, layout Preferred viewing angle
Final Concept Generation
The solution is a customized and flexible system that displays only what is relevant to each user. There are different levels of password security, display reading angles, and information display depending on the user’s preference and role. The dynamic keyboard allows for various placement of numbers and simple icons.

The RFID identifies: User name or ID Disability notification Administrative capabilities Preferred language and angle of keypad and screen display after an initial one time setting.
