My Inner Inventor

Sometimes, I come up with strange ideas of things that I would invent if I were skilled enough to invent things (or had the money to hire people who did).
A debit card with a dot that changed color depending on your account balance, or cars with magnets that repelled against other cars (no more accidents?)

I thought of another invention yesterday: technology emotion sensors. When I receive an email or text, my phone makes the same sound no matter the content of the message. My text sound happens to be very happy-sounding chime, so it always throws me off a bit when the happy chime chimes and the text is bad/sad news. With technology emotion sensors, the sound would adjust according to the content of the message. If the text said "Grandpa died" the corresponding sound would be somber vs. if they text read, "just won the lottery!!!!!!!!!!!"--happy sound. Of course, this invention would involve an invasion of privacy to some extent because the emotion-sensing computer/robot would have to scan the message for content. Overall, I think it would be helpful. One day if I have money I will hire a fresh-out-of-school techie to invent it for me.
