Among the variety of equipment and accessories for study, presentations and infobusinesses a special place is occupied by interactive boards. Being essentially a large touch screen, and functioning in close conjunction with the projector and the manager computer, this device gives a lot of new opportunities lecturers, coaches, other information business specialists, and significantly facilitate their work. Today we will consider a short rating interactive whiteboards of various types and manufacturers that experts considered the best in its class. But first, briefly go through the classifications and give you some tips for choosing these kind of devices.

How to choose an interactive whiteboard
Interactive whiteboards vary quite significantly in principle work and implemented technological solutions. Select specific models are most often dictated by a combination of key technical characteristics. We will list them below, but first, some general universal tips.
Before you buy such a very expensive thing as interactive whiteboard, some preparatory work and take into account some recommendations.
One-stop Tip – Pre-Learn Information at the Internet about suitable models. Pay attention to reviews users. Take an interest in having dealerships manufacturers in your city – it will depend on how much You will have to wait for a solution to the problem during the warranty case. All this seems obvious, but so many ignore this stage, and too in a hurry with the purchase.
It is highly advisable to buy a complete set at once – board + projector. This will achieve maximum compatibility, and in some cases, a board with a “non-native” projector useless.
The scope of delivery must have a set of fasteners elements and fixtures, as well as installation instructions.
Choose a board with a matte finish. As an option – boards anti-glare, but matte is still preferable.
Interactive whiteboards also differ in the type of projection – direct or reverse. The straight line suggests the location of the proctor in front boards, reverse – behind. The first option is cheaper and easier to plan. mounting the board itself – you can simply hang it on the wall. Second the option is good in that the beam of the projector does not interfere with the lecturer, and he himself does not casts a shadow. But rear projection systems are significantly more expensive, and installation of the board requires highly specialized services specialist.
Reading the position of the stylus or finger / fingers of the lecturer is the key to the very interactivity due to which such solutions make sense. There are several ways to do this:
- Electromagnetic. The entire area of the canvas boards inside its structures are lattices of contact conductors. At touching the surface with a stylus, the place of contact is determined instantly and for sure. Such boards are relatively inexpensive, solid, in general reliable and durable, can be equipped with anti-vandal coated. On the other hand, such boards are susceptible to EM interference, you can work with them only with a stylus.
- Resistive. The principle here is the same as that of touch phones that were before the advent of the era of capacitive screens. Contact location is determined due to physical clicks. Here it is already possible to use not only the stylus, but also just with your fingers. The main disadvantage is a slight delay between touching and system response.
- Infrared. Sensors are located inside the perimeter, which determine the place of touch. Has almost everything advantages of resistive technology, plus it’s not afraid damage to the canvas, or rather, damage does not negatively affect on functionality. Cons – for the most part, a high price, sensitivity to interference.
- Optic. At the corners are miniature digital cameras at a certain angle to the canvas. Two cameras are enough, but four is better. You can work with the board with any opaque objects, but the positioning accuracy in such a solution is worse than in any of the above.
There are other recognition and positioning technologies such as like laser or microdot, but they are much less common and for the most part too expensive.
On this basis, active and passive boards are distinguished. Active powered by mains and connected directly to to the computer. The second is completely autonomous. Passive interactive boards have significantly less room for use technologies, so there are few of their types – micro-point, magnetic and several others. In our rating only active boards are present.
An extremely important parameter on which depends on which audience, and also what kind of information material will be calculated the board is directly at work.
Actually, the size of the board can be measured by the lengths of the sides, but more often this parameter is determined by the diagonal, as in TVs or monitors. An additional parameter is the aspect ratio. More than diagonal, the more viewers will be able to fully perceive information on the screen. Estimated calculations are as follows:
- from 2 to 10 viewers – at least 50 inches;
- from 10 to 25 viewers – from 60 to 90 inches;
- from 50 viewers – from 91 to 105 inches.
The data are based on the calculation that the size of the room is minimal. The larger the room, the larger board sizes will be needed for the same number of viewers.
It is also worth considering that many models contain so-called non-interactive areas around the edges that reduce useful area.
The technical features of an interactive whiteboard alone are not enough. so that it becomes a convenient multi-functional tool. That functionality directly depends on the software. This point must also be checked with the manufacturer or at a point sales and compare with the future use of the board. For example, if the board is supposed to be used at school on an ongoing basis, software must be as complete as possible or at least standard set of interactive software tools: ruler, compass, protractor, etc.
Another important aspect with regards to software is availability Russian localization. It must be complete, including instructions and updates. An exception may be unless if the board will be permanently used in an English class language.

Smart Board SB480IV4
Another smart whiteboard in our ranking formally has slightly less functionality than the previous solution, but is not without some qualities that characterize it on the good side.
SB480IV4 is an entire interactive kit that includes the board itself is included, a short-focus projector with a remote control remote control and accessory kit. SMART V30 Projector transmits an image with a resolution of XGA (1024×768) and the ratio sides 4: 3; supports HDTV via HDMI 1.4 input. Also a projector has a built-in 5-watt speaker.
This solution uses the same optical technology. gesture recognition DViT, as in the previous model, but no longer so perfect – only two cameras are used. This allows use the board at the same time no more than two people.
The size of the canvas board – 157×117 (77 inches). Image brightness under optimal conditions of external lighting reaches 3000 lm, contrast – up to 2900 to 1. Lamp life in standard mode operation is 6500 hours, in economical – up to 8000.
