Sometime simple solutions gets great results! 😉
I was in a conference and I a colleague of mine asked me if I could make a demo (from remote) of an app I developed and that I have locally on my smartphone. The solution I adopted was simple but effective and I want now to explain you, just in case you need in the future!
First, I started a simple phone call to allow me to explain the demo in real-time (I preferred not to use a skype videoconference to leave bandwidth).
Second, I started on my WP8 Lumia smartphone the Nokia Beamer app. This app allows you to send by email, SMS or a social network, the link of a web page where it will be shared the screen of your WP8 smartphone: it is possible then to choose to have an update every shake of the smartphone or (better) to make an automatic update that allows a real-time transmission of every change it happens on the phone screen. When that email arrive, the remote user has only to click the provided link (e.g. https://sb.beam.nokia.com/sb/session/BEnsXaTxhG) and on his browser he will see a copy of the screen of the remote WP8 smartphone.
Third, obviously leaving both the phone call and the Nokia Beamer app running in background, I had only to launch my app and make the demo making a real-time explanation of each phase through the normal phone call I started at the beginning.
PS (11/9/2015): unfortunately Lumia Beamer, the new name that was given to Nokia Beamer won’t be suppoted nay morte after 10/10/2015 (see Microsoft to end support for several Lumia Windows Phone apps on October 30)
But I want to tell you another tip that may be you don’t know: the use of the Office Remote app to use your smartphone as a remote controller to drive an office application on your PC (e.g. a Power Point presentation). And also this nice feature can be used easely by everyone!
On your WP8 smartphone, you activate the Bluetooth and launch the Office Remote app. On the other hand, desktop side, the add-in for Office Remote must be installed on the PC if not already There.
Then enable the Bluetooth also on the PC (possibly connected to a projector) where there are your slides/documents you want to show; make the Bluetooth pairing between the PC and the smartphone.
On your smartphone the Office Remote app shows you (as shown in figure) all the opened Office documents on the paired PC so you can select the one you want to control remotely.
In the following figures you can see some screeshot of this app’s user interface, in particular the ones to control the progression of a power point presentation and the moving inside a word document.
Last but not least, remember that now with WP8.1 there is the ability to project your phone screen onto a PC, TV or a projector. In particular in Windows Phone 8.1, there are two ways to project your screen:
Wireless: projecting your screen wirelessly uses Miracast technology. This requires a compatible receiver (e.g. a Smart TV, or something like the Netgear PTV3000), and will only be supported on newer WP 8.1 handsets.
USB: to project your screen via USB, you need a PC running the Project My Screen app. Simply install the app on your PC and launch it, then connect your phone and it should pop up a prompt asking you if you want to allow screen projection.
