I'd suggest the "To improve how people navigate on earth" to still be a poor description. It doesn't use the jargon, but it also doesn't tell anybody about what the thing is/does/how people will use it. It completely lacks emotion and connection to a consumer.<p>"A map on your phone so you can get directions no matter where you are"<p>"A better location system so you can find the place you're looking for without having to look at or read directions"<p>I'd suggest "to improve" is not a goal, your description needs to be more concrete, yet flexible enough that you aren't limiting other peoples imaginative use of your product.
