We decide to use the light, sound, aroma, and temperature as the product's functions. Building an IoT device was a big challenge, but the most important thing we took into consideration for building a prototype was implementing sustainable design. We decided to build a minimum viable product to put on display.
Once we have a clear detail of the product functions and specs, we started to build the OSO application. Before started it, I created the app map to organized the features and the content architecture based on the product. Then created the user flow for the different paths that users would take through the products to complete each task.
Before testing began, with regards to the task flow and prototype, we made some initial assumptions to help us better understand our users. Throughout testing notes and feedback were taken into consideration for each round of iteration.
Task 1: Use the app to start the sleeping mode.
Task 2: Use the app to control the product functions(brightness, volume, aroma, and temperature)
Task 3: Find the setting function in the app.
•Most participants clicked the "Let's sleep" on the home page, but after they click it the screen will pop out another screen of "Timer Setting".
•Most participants think it should have an easier way to start the products instead of click many steps.
•Most participants misunderstood the icons, such as the home icon, music icon, and aroma icon.
