When people think about the action of waving, it is pretty universally accepted as a greeting. However, waving can beckon someone over, can be out of pure politeness, can be a mean of dismissal, or can imply a host of other things. How are we to know exactly what someone intends by this simply gesture? Hey U, a brand new app released today for the iPhone and iPod Touch, attempts to bring some clarity (and fun!) to the act of waving. When using Hey U, you type a short message, wave your phone or iPod, and the message is briefly conveyed in the air to your target. Even though the actual act of waving may not be as graceful due to the presence of a device in your hand (which begs a warning: do NOT wave vigorously), everyone will know exactly what you wish to convey. With Hey U, a previously unoriginal acknowledgement gains a personal touch.
