Live Demonstration starts from 2:10 to 3:26
Stage 1: Research
In the beginning of this project development. I have done background research on the breathing skill types and impact. Also 2 interviews related to panic attack and phobias were conducted to understand more about the target audience. I summarised some essential condition of this product in order to fit the need of this user group. This device should be portable, light in weight and hard to break.
Stage 2: First Prototype
The first prototype is consisted of three major parts, heart rate sensor, OLED screen, and the combination of a LED light and microphone. The testing flow is similar to the current prototype, the only difference is the microphone is installed to allow users to interact with the system. If the user is doing the right action, for example, the led light switched on when the microphone detect input from the microphone. But based on the user testing result, the users indicated that the microphone made them nervous because when the microphone did not sense the input correctly, the LED light started blinking which confused the users.
Stage 3: Second Prototype
The second prototype removed the microphone, which was the one shown on the video on top. After the Video demonstration, three groups had left comments to my prototype. They indicated two major problems, the first one was the lack of interactivity, there was no feedback returning to the users when they were doing the 4-7-8 breathing practice. Also, the LED light were under the box which was not obvious enough to let them see clearly. And there was a lack of instruction of the 4-7-8 breathing practice.
Stage 4: Third Prototype
The current prototype, for interactiveity, i have used buzzer as an indicator and microphone that wrapped with paper to increase the accuracy. But the user testing result indicated that, the user’s attension was drawn, so that they were trying to get the feedback correctly, instead of focusing on practicing 4-7-8 itself. None of the participants could reduce their heart rate to 100 or below. They feel nervous when they are always at the irregular heart rate status. In the final prototype, i am not using microphone and buzzer to maintain the effectiveness of 4-7-8 breathing techniques. I have put the LED light above the box, so that user can see the LED indicator clearly that remind them which breathing stage they are at. Also, in order to give them better users expereince, I have stick a paper filled with the whole testing process in text is written on the white paper box.
