IP Week-6 Design & Sound Effect

Since the last few design ideas were not good enough and there were few drafts, I thought about a few more design ideas this week.





After asking others what they think, most agree that this one is more aesthetically pleasing.



Regarding sound effects, I plan to use the sound of water droplets on YouTube as the sound effects of various reactions on the phone dock. Here is the link that I will use as the sound effects for the product.

When the user puts the mobile phone down on the phone dock, there will be a sound of water droplets to indicate that the phone dock is starting to work, and the user should start to focus on their work. When the user's mobile phone receives a message and wants to reply, the user can pick up the mobile phone and reply to the message. When the user picks up the phone for more than 20 seconds, the phone dock will make a rapid water drop sound, and then the water drop sound will become slower and slower until it stops. This indicates that the water droplets have stopped and no longer dripping on the stone. Of course, if the user does not want to continue working, they only need to press the button on the phone dock, and then the phone dock will play a unique water drop sound to indicate that it stops working.


At the same time, I asked 4 target users what they thought about sound effects this week. They all said that the sound effect when putting down the phone can let them effectively know that the phone dock is working. But regarding the sound effect when the user picks up the phone for more than 20 seconds, the 4 users have different opinions. 1 user thinks that the sound effect was a bit scary. 3 of the users said that the sound effect was annoying but didn't give a strong feeling to them to put back their phone. Finally, the sound effect of the end, that unique sound effect can make them feel the feeling of the end but the ambiance sound effect can be longer, which would give users a sense of release. Regarding the concept itself, they said that it gave them a certain degree of strength to help them concentrate on their work.



In addition, this week I tried using an SD card reader to play sound, but it didn't work. Then I tried to use the DFPlayer mini module to play the sound, but it didn't work as well. After I refer to the DFPlayer mini connection diagram, I realized that I connected a wire to the wrong pin, and at the same time I forgot to use a resistor, so it couldn't work.

IP Week-14 Refine Concept & WIP

Image
I tried to change a bit my concept because after I listen to my lecturer's feedback. My lecturer said it's better to have a sound effect when the user is self-regulating. So, I was thinking if the phone dock has 2 modes, one is normal wireless charging, another one is self-regulation wireless charging. Therefore, I can have more sound effects to apply in my product, which are Open SFX, Self-regulation SFX, Warning SFX, and Shut Down SFX. However, after consulting the lecturer, my lecturer said this would be different from what I originally intended.  Because now users have options, they can choose not to use the self-regulation feature. But my purpose is to let people know how to self-regulate. So, I gave up using this concept and using the previous concept. At the same time, I received some feedback from my peers, some of them said that the prototype 2.0's light line should be wider. Some of them think the outcome will too big, and suggested I can create another version of...

IP Week-11 Choose Design & Concept

Image
Based on two designs from last week, I chose to use trees as my design concept. Concept (Tree):  The road to success is always difficult, just like the process of growing a sapling into a big tree. When the user puts down the phone, the trees have a white light that fades in and out, which means they're trying to grow (to achieve success). When the user picks up the phone, the tree shows an orange fade, which means the tree has no input and it going to dies. After 20s, if the user still hasn't put the phone back on the Dock, the tree will show the red light fading out (the tree is dead). Function test: Stop timer Timer sound & light effect The sounds effect used in the prototype: https://www.youtube.com/watch?v=1TTSWWobIQE https://www.youtube.com/watch?v=0tOn5hWBTjs

IP Week-10 Prototype 1.0

Image
This week I simply experimented with different states of buttons to show different lighting effects. Press and hold the button to display a light blue breathing light effect; release it, there will be a dark blue light effect for 2 seconds; press it again quickly to cancel the dark blue light effect immediately. Besides, I have also reduced the power sources of the prototype. Previously it required 2 power sources to work (one for Arduino, another one for wireless charger). Now I extend the wires from 5v2a adapter to provide power for Arduino and wireless charger. Now it looks cleaner than before. before: now: RGB lighting effect: After that, I successfully made the RGB have different effects according to the button state, and I integrated the DFPlayer mini into the component. When the button is pressed, DFPlayer mini will start playing the sound; when the button is released, the sound will stop. When all the components are ready, I start integrating them into a certain size. To be mor...
