Story:
Jack studies abroad in Australia where he has much homework and has to spend some time on the trivial by himself. He needs to make priorities for all his tasks including research and daily activities, such as buying food or doing exercise. It is common to use a to-do list, but you may forget it anyway. For example, a month earlier, he knew his speaker was out of battery. But he didn’t have time to go out so he wrote a to-do list, hoping someday he would go to a supermarket to buy batteries. Several weeks later, he invited his friends to his home. To make preparation, he went to the supermarket to buy vegetables and snacks, but buying batteries were forgotten. After his friends arrived at his home, a friend said, what about playing some music? He replied,” sorry, my speaker is in low charge”.
Solution one:
An intelligent hat equipped with a 3600-degree camera can remind you of the stuff you
wrote on your to do list.
1. Input the stuff you need to buy and upload the image of the stuff through an app.
2. The intelligent hat will remind you of the things you need when the camera finds the similar material based on Content-based Image Retrieval technology.
3. It saved your time and energy to check the to-do list.

Solution 2
Based on that scenario, another solution is to create an app. You can input your desired
stuff and the places where you can buy it. When the app detects you arrive at the areas
which you can get the material, a notification will be sent to remind you.
