This paper presents a prototype of virtual transparency on a hand-held device. The prototype is restricted to such device with no additional material to show that a semblance of virtual transparency can be achieved with today's smartphones and has been designed be as simple as possible to use. The user's head is tracked using the front camera and the eyes co-ordinates are estimated from the head position. The area to be displayed is then computed from the these coordinates, an estimation of the distance head-phone and phone-scene, as well as the phone and lens specifications. It provides a realistic illusion of virtual transparency, not an geometrically accurate render of the scene, and still works in non-optimal situations (non-flat scene).
