Interactive touch screen : the best choice for a fixed installation.
If everyone had the budget for it, touch screens would equip every classroom or meeting room.
Interactive touch screens offer many advantages compared to interactive video projectors or whiteboards (or compared to equipments that incorporate video projectors).
What’s more is that touch screens are equipped with an Android OS et can be manipulated exactly like a giant iPad (or a giant Android tablet). They work exactly like touch tablets and go up to 2,3m in diagonal size !
- image quality is much higher (whether it be in terms of contrast, sharpness or definition)
- no adjustment is required to obtain high image quality (whereas an ultra-short-throw projector requires a competent installator to obtain good image quality)
- touch screen lifespan is 10 times longer to that of an interactive video projector (about 50 000 hours compared to 5 000 for a high-quality projection lamp)
- zero cast shadows when you take notes on a touch screen. Note-taking is a painless process on a touch screen whereas a video projector, even an ultra-short-throw one, always casts a least a few shadows
- no risk of glare on a touch screen
- interactivity possibilities are incomparable on a touch screen (finger or stylus pen) because sensors are located all around the screen
Touch screen diagonal size can be half the projection size of an equivalent interactive video projector for the same reading distance
The answer is no.
This conclusion can be drawn by doing a Snellen test on a 55″ touch screen and 110″ interactive video projector.
Simply comparing a touch screen’s diagonal size to the projection size of a video projector is a mistake. Touch screens have excellent image resolution and quality, to obtain similar levels of quality, a video projector has to have a projection size twice the size of a regular touch screen.1.
The diagonal size of an interactive touch screen must be half the size of an interactive video projector for the image to have the same resolution.
Interactive touch screen, video projector or whiteboard ?
The price gap between a touch screen and an interactive video projector is closing
Price comparison between touch screens and interactive video projectors
In 2008, a 65″ touch screen cost around 10 000€. Today it costs less than 4 000€ (with prices still continuing to drop).
A 55″ screen today costs less than 3 000€.
If we compare this to the price of an interactive projector which costs 1 500€, you still have to take into account installation, maintenance and depreciation costs.
For small rooms, choose an interactive touch screen
For all those who work with small groups (less than 20 people), our recommendation is to systematically choose a touch screen either a 55″ or a 65″. For the same price as a video projector, the image quality is incomparably better.
This recommendation is for :
- all businesses wishing to equip a 20-person meeting room
- kingergarden to year 1 primary school classrooms where groups are relatively small (15 / 25 students max, usually less).
Beyond 30 people, either a touch screen or an interactive video projector depending on the budget… and the investment package
The unique advantage of a interactive video projector lies in its projection size (2 to 2,50m in diagonal size) which can be obtained at a reduced price (approx. 1 500 € excl. tax ). Average lifespan is 3 to 5 years inclusing several support and maintenance operations (lamp, filter) which can be estimated at around 1 000€. An 84″ touch screen (2,13 m in diagonal) costs today less than 7 000€ and has a 10 year average lifespan with zero maintenance costs.
It is quite clear that a 84″ interactive touch screen offers greatly superior quality and has an annual cost around 700€ compared to 600 €/year at best for an interactive video projector.
Interactive touch screens available in our shop
For bigger rooms, interactive video projectors can be a good alternative
What’s more, they usually don’t offer the possibility to absorb the investment over a period of 5 to 10 years and have to work within tight budgets.
In this case, we recommend buying an interactive video projector.
For businesses that have to equip a similar room but have the financial ability to spread out the investment (loan, leasing agreement or depreciation), we recommend buying a large touch screen.
Interactive whiteboards are no longer the norm
Interactive whiteboards come in two separate parts : a video projector and an interactive screen.
The interactive technology is usually built into the whiteboard therefore fragile.
Its installation is more labour-intensive than for an interactive touch screen or an interactive videoprojector.
This type of equipment was very popular around 2010 but for all the reasons mentioned above, except for very specific cases, we recommend purchasing an interactive video projector or a touch screen.
… unless they use mobile whiteboard technology
On the other hand, mobile interactive whiteboards have very specific advantages and continue to be widely employed in schools and businesses (approx. 50% of the equipment we sell and 25% of the French market according to our estimations).
- A mobile interactive whiteboard such as the eBeam Edge can be shared between users (which avoids having to equip different rooms)
- It’s very cost-effective and easy to use
- Zero installation costs

Whether they are integrated to mobile interactive cases (mobile interactive video projectors) such as the VanITy Bag or the mini-ITsac, mobile interactive whiteboards are widely used in schools and require up to 10 times less investment.
