Idea 1:
Choosing colors is not an easy task, at least for me. Every person working in the digital industry has faced or used a Newton wheel at some point in his life. Color Palette suggestion Tools like Adobe Color are very helpful. But what about the physical industry? How inconvenient it is to know the exact color of a physical object and use the online color suggestion tools. The color calculator will come in handy at these times. It will have a single pixel camera (color sensor) and will do the math based on the input and display the suggested palette in the 4 blocks.
The most important thing any dentist or tooth-care research paper will tell us is to brush regularly for at least 2 minutes. Toothpaste and brush are not as important as the time. Yet the dental industry will sell us products on different parameters like arrangement of bristles etc. Even the smart brushes only indicate the time that you have brushed , that too on the smart phone, which you typically will check after finishing the brushing regime. Moreover brushing twice daily is still a wishlist for many people. They just cant do it at night.
Imagine that you forget to brush at night, and a message goes to your boss that you did not brush. I believe this embarrassment will force you to brush your teeth. The toothbrush will use a vibration sensor, and keep track of the time of vibration. If it detects 2 cycles within 24 hours, it will not do anything, else it will post a shameful message on facebook / instagram or any other media on your behalf.
This is a persistent translator that will help you remember the word you asked it. When you ask for a translation by voice, it will provide the translation. After a while or when it detects motion next or turns on next, it will ask for the translation again, if you succeed the lamp will stay on, else the lamp will turn off. The experience part of it still needs to be refined. I plan to use the Google Speech to text API & Yandex Translate API for achieving this.
