In my Light, Sound and Time class I was assigned to invent a time-telling device that is better than what’s already out there. The time-telling device that I decided to do was a book bag that tells you the time by the hour with a light that flashes from the straps which will vibrate too. The most challenging thing was getting the math part together and figuring out how to show the math concept for this device. What I learned from this was the different ways that time can be told or recognized. I learned that sun’s shadow can tell you the time wherever you are if you measure it right. What I am most proud of is choosing my time-telling device on time and not making it so complicated.
Book Bag Time
The time-telling device I chose to do was a book bag. The straps of the book bag light up within the hour. How the book bag lights up is by the warmth of the human body, it will also vibrate when the light flashes. When the book bag is worn, the book bag then activates itself when it starts receiving the body heat from your body. For example, if you saw that the time was 2:00 pm and your book bag straps light and vibrate up that means it has been an hour meaning it’s 3:00 pm. This book bag is also a timer, you can plug your earphones into your book bag and the device will let you know how close you are getting from your time being up. How my device shows Light, Sound and Time is, with the energy that the book bag is receiving from your body the book bag will light up when the time has changed. The timer has a programmed speaker so when you plug in your earphones the speaker will tell you how much time you have left from what you put the timer for. Last but not least, Time; every time the time changes by the hour the light and vibration from the straps will let you know it’s been a full hour.
My device is meaningful and effective because instead of wearing a wristwatch, you can simply tell when it hits a different hour when the light flashes and when you feel the vibration on your shoulders. You can also put in a time you have to be somewhere and it’ll let you know when your time is up. As I was researching about book bags, I found that book bags were started to be invented in California by two couples named Dick and Nena Kelty. The Kelty’s started making bags in their California home in the early 1950’s. As I was researching, the article said “the unassuming Kelty backpack signaled a paradigm shift in backpack design by prioritizing three fundamental modern concepts”:
Weight Matters
Durable Materials are Key
User Experience is Important
How my device solves common problems today is by the light that flashes and vibrates because the light flashes when it’s been a hour. If you know what time it was before you won’t have to check your time. The timer is just regular but you can also plug in your earphones and it can tell you how close you are from the time being done. Teenagers and people with low hearing or that are blind today will be able to use these book bags.
