MesoSystems BioCapture 650
Design a portable device for one handed use with critical consideration of the user interface and human factors for a first responder in a threat condition wearing typical protective clothing and using other emergency equipment.
The design process started with a user centric market audit including interviews with firefighters and first responders. A task analysis was developed to fully understand how a potential threat condition is approached and how a first responder acquires samples for testing. As prototypes evolved Stratos conducted human factors evaluations using gloves typically worn with Level A HazMat protective suits to test design assumptions and quantify usability solutions. Graphical and physical user interface scenarios were evaluated for visual, audible, and tactile viability.
The resulting design balanced the product's 8lb weight for comfortable handle grip during the 5 minute collection cycle and a variety of use positions. The disposable cartridge evolved to enable easy installation and replacement while used in a contaminated environment. The graphical interface incorporated a backlit display orientation and font size for constant visual contact through protective clothing. Visual and audible indicators were also incorporated to quickly indicate operational modes and error conditions. Cosmetic features were all designed to enable ease of cleaning and decontamination as well as communicate the visual language of an emergency threat response device.
Over a half dozen different configurations were explored and evaluated to optimize market acceptance, human factors, ease of use, and environmental functional requirements meeting the user goals of the project.
