We describe the early development of an experimental outdoor mobile augmented reality (AR) application, AR street view,‖ running on a Google Android Dev Phone 1. This project addresses the design of interaction and visualization techniques for AR user interfaces on mobile phones. Our experience suggests that usabili-ty is compromised by a variety of issues, including tracking and registration errors caused by the relatively inaccurate GPS and orientation sensor, the need to hold the phone away from the body in potentially awkward poses, and the relatively small field of view covered by the display and camera.
Who uses WhatsApp Messenger? From The look of the Play Store listing , a damn lot of people. Considering it's so popular, it's probably a pretty secure app, right? Think again. WhatsApp actually sends all chats in plaintext , so anyone on the same Wi-Fi network can easily pull your entire conversation - including pictures and videos - straight out of the air. And now, that process is even easier than ever thanks to a new app called WhatsAppSniffer . It's basically just a packet sniffer, but it makes the process of pulling WhatsApp chats out of the sky stupid-easy, and that's never a good thing. You might as well just shout your private conversations across the room.
