Medical Laser Application

Medical Laser Tablet Application

Overview

I was hired as a freelancer by a large medical device manufacturer to design the interface of a new dermatological laser product for treating vericose veins. The UI I designed here would eventually be developed for a proprietary, touch tablet device which was mounted to the large product.

This was an exciting project as I learned about a new industry, and the best practices of interface design for touch input. A doctor's mistaken input on the device could have serious implicaiton, so I worked hard to make the experience as clear and approachable as possible.

After meeting with the prodcut team in-person to dicsuss the project scope and requirements, I began the design process by creating a user flow for the application. The functionality of the product was fairly straightforward, with most user (doctor) input happening on one dashboard interface. 

There was one other user type who would access the device, and this was a company service technician. For this user role, I outlined a separate mode in which thye could access advanced settings anf product controls. 

After a few iterations on the user flow, making refinements as necessary and discussing with my client, we approved the flows and moved forward. My next step was to propose a few unique look and feels for the application's UI. My client wanted this product to stand out as being a modern interface, giving them a leg up over their competition. 

It also needed to be dead-simple to use for the doctor's administering the dermatological laser treatments using the tool. I proposed three diffreent options with unique navigational structures and visual treatments for us to discuss. Giving my client a few different options is a great way to open up the conversation and start to get everyone talking about the possibilities. 

We decided to move forward with a variant of option B as it most clearly presented the information while also representing the ethos of the company brand. 

At this point I began applying the UI direction to all of our defined screens in the user flow and developing a design system for the application. The cards interface on the home dashboard includes variable states depending on the device's data. This includes the laser status, aiming beam state and RFID card status. 

The final UI system came together as a successful design that was excitedly approved by my client's product team. We collaborated via InVision's inspect mode and comments system to define the development requirements.
