Does Upoint work with back-projected screens, plasma TVs and LCD TVs?
Yes. The Upoint sensors allow it to calculate where it is pointing on the area of space where the computer-generated images are, completely independent of which technology is used to generate those images (e.g., back projector, normal projector, TV, plasma or LCD screen, etc, etc).
Do I need the PinPoints or can I just buy the Upoint wand?
You don’t need the PinPoints, but they’re good to have. Without the PinPoints, you can control the cursor by ‘pulling’ it out of the display’s top-right corner when you want to use it - this is known as Cursor Grabbing. With PinPoints, you simply point to where you want the cursor to be and it will appear there automatically.
Are the PinPoints connected to anything else?
No. The PinPoints are fully self-contained units, powered by their own battery, although you can actually hook them up to a continuous power source so that they are always charged. This is however not necessary. When the power on the PinPoints goes low, it will start flashing red periodically, to warn you that it needs a recharge.
Do I need to calibrate the PinPoints?
No. You simply fix the 2 PinPoints to the corners of the display. In fact, the default setup procedure during which the wand is aligned with the screen is exactly the same with or without the PinPoints. The system searches for and recognizes the PinPoints completely automatically - so you won’t even know they’re there.
How does the system know where I’m pointing?
The compass/gyro combination inside the wand tells it where it is pointing with respect to Gravity and North. During the one-time setup, the user tells the system where the display is by pointing to its corners. After that, the system simply calculates where the wand’s pointing line intersects the display, and positions the cursor accordingly.
Some of the other in-air mice such as the Gyromouse don't have to be pointed at the display at all to control the cursor. That flexibility makes them a lot better than Upoint, doesn't it?
Actually, the non-laserlike pointing offered by some of Upoint's competitors makes them far less userfriendly! After all, laser pointers are still by far the most popular tool used by presenters, as the way you point with it is so much like pointing with our own finger. Upoint's creators realized this a long time ago, and therefore created this 'direct-pointing' system.
How long can the PinPoints work on a single charge?
With normal use, you'll only need to recharge the PinPoints every few days.
How long can the Upoint wand work on a single charge?
With normal use, you'll only need to recharge the wand every few days.
How many PinPoints do I need?
Actually, you don’t need any PinPoints at all: the wand can work stand-alone, and allows you to drag the cursor out of the display’s top right corner any time you need it (‘cursor grabbing’). However, when you want the cursor to simply appear where you point straight away, you’ll need at least 2 PinPoints – enough to triangulate the position of the wand if the podium that you present from is level. If it is not, or if you require more power in really large rooms, you can add up to 10 PinPoints in total - all will be recognized automatically by the system, and you will be asked to point to each of them as part of the initial one-time setup.
How do I recharge the Upoint wand and the PinPoints?
Both the wand and the PinPoints are fitted with mini USB connectors that you can use with a normal USB cable to connect to a power source such as a laptop. You can even recharge them while they are in use!.
Can I activate buttons, menus etc that I point at?
Absolutely! When you work with Upoint you control the regular mouse cursor, moving it around as intuitively as you move around the laser dot of a normal laser pointer. Hence, all the things you do with a normal in-air or on-desk mouse can be done with Upoint - but in a far more intuitive way!.
How accurate does Upoint compute the point-of-aim?
Even with the high-accuracy state-of-the-art sensors inside Upoint, there will be a small error in calculating where the remote is pointing. However, since it is the size of this error in relation to the size of the display that is the important factor, this error is negligible when Upoint is used in its intended environment, which is large-screen presentation venues. That said, Upoint may be slightly less effective when used with, for example, a 20” computer monitor.
