For the last challenge I decided to develop the pillbox since I think it is very useful for old people and I know from personal experience that a lot of people forget about taking the right amount of pills at the right time and this device takes care of all those issues!
In the picture below you can see the pillbox and an additional wristwatch.
Old people can take this box to the doctor and he/she puts the right amount of pills into each container. There is one container for every single day of the week. Doctors also can program an alarm so that the pillbox reminds the person to take the pills. The speakers are for the alarm and they also read out the text that is displayed on the touchscreen. On the touchscreen the person can read what day/date it is and general information such as weather, news but also personal information (events, other alarms etc). Buttons make it possible to interact with the content on the screen in case the person does not like to use the touchscreen and there is also a button to turn the device on/off.
In case the person is not in the room or simply does not hear the alarm that is coming out of the speakers of the pillbox then there is a wristwatch that is connected via WiFi and the alarm also goes off on the wristwatch (vibration/sound).
To the best of my knowledge there is no such device on the market yet, however a lot of non-digital pillboxes are already out there. The wristwatch is a great addition to this technology since it makes it almost impossible for an old person to miss the alarm to take the pills.
Pretty much all of the functions and ideas are already out there but nobody has combined them in this way yet and I think it would help a lot of old people. Overall this technology is quite affordable and it will not take long time until it is on the market because of its simplicity.
