The OSIM uGoGo is a handheld, portable massager that stimulates muscles through electrical pulse (EMS). A redesign based on OSIM's successful ProTherapist massager, the uGoGo is highly ergonomic - meant mainly for older consumers. Nevertheless, it also attracted younger users, especially executives and young, working adults.
I worked closely with design consultants to develop the usability design for the uGoGo. I created the interaction flows and defined the interface design as well as its CMF specifications for the product. I was humbled by the experience gained through this project: I learned to be more sensible to ergonomics and human factors when designing for older consumers.
I worked closely with the Product Development and Marketing teams to create user personas for the uGoGo. We conducted market and user research based on data obtained for the ProTherapist, gathering feedback and user insights.
I conceptualized the CMF designs based on the personas and research insights, after which I conducted a user feedback session to gather opinions and to help finalize the CMF design. I documented the final information into a control specification.
I evaluated production samples to provide feedback as well as design solutions to make sure that the uGoGo end product stayed true to its original design intent - which required many tedious rounds of iterations before we were able to sign off on for manufacturing production. In addition, I tested all interaction components and cataloged all defects in a design control document.
Based on the UX platform, I created the user experience and interaction workflows for the uGoGo and conducted user studies to validate the design concepts. The challenge I faced when designing this product was the careful attention for older users when designing for hand grip, finger strength, and legibility - as well as ease of understanding the user interface. I refined the designs based on the comments collected and documented all the final workflows into a specification. The engineers and quality assurance teams used this specification as the standard reference for the product development and testing.
