Always Do a Trial Run
Once the connection is established, the file transfer to the appliance
begins by way of the Bluetooth connection, but the process can be very slow. In
my tests, a 5GB, 15-slide PowerPoint presentation took anywhere from 6 to 12 minutes to transfer fully. While I
could start the presentation once the first few slides had transferred, I found
the transitions between slides as well as on-screen animations to be very
sluggish with the file transfer still in progress, sometimes taking up to 10
seconds to advance from one slide to the next.
Therefore, I would advise users to transfer the presentation to the device
prior to the meeting, as the Presenter appliance has onboard persistent storage
accessible only to Presenter-enabled BlackBerrys. As this memory is persistent
across a device reboot, users should periodically wipe the appliance memory to
avoid leaving potentially sensitive corporate data behind on unsecured device.
An appliance wipe command can be triggered from the Presenter software menus.
With the presentation displayed on the external display unit, I could move
to the next slide by depressing the BlackBerry track ball or track pad twice. I
could also navigate to the previous slide or skip to a specific slide, or set
the slides to advance forward at a specified interval. Presenters can also pop
up their notes for a particular slide on the BlackBerry, while the main slide
appears on the external display. I could also blank the external screen with
the presentation still showing on the BlackBerry.
While many presentations used in my tests displayed well via the Presenter,
I found it could be finicky with some files. RIM's documentation states that
all presentations must be formatted with a 4:3 landscape orientation, although
in my tests I was successfully able to display very basic slides in both 16:10
landscape and 4:3 portrait via the Presenter, although the latter was
definitely off-center on the external display.
Of more concern, I found that with some presentations tables or pictures
that looked fine on a PC failed to render correctly within the Presenter
software and via the Presenter appliance. Also, on occasion, file transfer
would halt midstream and the presentation would fail to show on the external
display at all. Size appears to matter, although perhaps more with the size of
an individual slide than of the presentation as a whole. For instance, I was able
to display a 256-slide, 13GB presentation via the Presenter, while a smaller 5GB
presentation with 10 extremely busy slides failed to load. RIM recommends
adjusting the amount of textual content and animations in troublesome slides to
decrease the size of individual slides, so it is important that users test all
the slides of the presentation prior to their meetings to avoid any glitches or
hang-ups.
Also, the BlackBerry Presenter does not extend its remote display
capabilities to any other formats or file types beyond PowerPoint. I found that
I could not use the device in conjunction with Word Documents, PDFs, photos or
even Keynote presentations.
During tests I once also found that my presentation kept looping on the
external display even though I had instructed the software to end the
presentation and had turned off the Bluetooth radio on the BlackBerry. In this
case, the only way to stop the presentation was to power down the Presenter
appliance.
Thankfully, it appears that RIM intends to deliver improvements for the BlackBerry
Presenter that hopefully will address some of these problems. The company has
already released a Presenter manager application for Windows that can install
firmware updates down the road, although none were available during my tests.
I also noted that the Presenter offers itself to Windows as an 8GB flash
drive, but I could not pretransfer files to the device in this manner, as the
storage available to Windows is not persistent once the appliance powers down.
