Stylus EMR

EMR stands for "Electromagnetic Resonance". It is a technology that is used in digital input pens.

This uses electromagnetic induction. A sensor field in the display or tablet generates an electromagnetic field. The pen contains a coil that interacts with this field.

The tip of the Stylus EMR offers 4,096 pressure levels, allowing you to vary the line width by applying different pressure, just like a real pencil. This ensures a very natural writing experience and high precision at the same time. Please note that the variation in line width depends on the end device used.

No. EMR pens do not require a battery as they draw their energy from the electromagnetic field of the tablet or screen.

However, please check the compatibility list and make sure that the EMR technology is available in the display of your end device before purchasing.

Regular use, especially with frequent writing, drawing or sketching, gradually wears down the tip of the pen. This can affect the precision and feel of the pen.

If the tip is worn, it can cause more friction on the surface of the tablet or screen. This can negatively affect the natural writing and drawing experience.

That's why we supply 5 pen tips right from the start, so that you are well equipped. You can easily pull out the old tip and insert a new one with the enclosed replacement pliers.

The scope of delivery includes 5 pen tips and interchangeable pliers for easy replacement.

If these are used up, you can find replacement tips here.

All Bookhoover variants are symmetrical and can be placed on either the left or right index finger to actively read and guide the eyes through the text.

Tip: Switch the Bookhoover to the non-dominant hand from time to time, read and write with this hand to challenge and train the brain anew.

Although it is natural to use the finger to focus on a text, as children do, this can be a hindrance as the finger is short and thick and covers too much text.

A longer object with a thin tip allows a wider field of view and offers a greater range of movement.

E-book reader Note: Here the finger would activate the screen.

The pen or similar must be actively held, which leads to constant strain on the hand muscles and the entire forearm. You will easily recognize the cramping of the hand and forearm when "holding the pen in the tweezer grip".

You also lose the ability of "natural finger movement" from the finger ball joint with a pen.

The Bookhoover as an eye guide combines the comfort and naturalness of your own finger by avoiding any kind of cramping, yet still offering the range of movement of a pen or a pointer.

Yes, the type of text lines you guide your eyes through is independent of the display. (classic books, printouts, eBooks on tablets or e-readers, newspapers, magazines, etc.) The pointing cap (pacer) is functionally the same for all Bookhoover variants as an eye guide.

Bookhoover® Graphite: The pencil tip can be unscrewed as a unit and replaced with a new one.

Bookhoover® Ink: The ballpoint pen pen unit can be unscrewed and fitted with a new refill.

Bookhoover® Stylus: Here, only the front tip is replaced after wear and tear. You can do this with the enclosed pliers.

Important: The pen variants and pen units are not interchangeable .

Info: The Bookhoover® Flow and the Bookhoover® Booky do not have an integrated pen.

The book cover is 3D printed from biocompatible PA12. We then insert the respective pen refills by hand to complete the reading tool. Thanks to state-of-the-art additive manufacturing, a completely new haptic product experience can be created.

The Bookhoover is produced using innovative 3D printing technology, the multi-jet fusion process. This allows its special filigree design and the flexible finger holder to be reproduced from just one material. It also allows a completely new haptic product experience to be created.

The 3D printed base bodies are then carefully assembled by hand with the respective pen unit.

Because you wished for it.

The Bookhoover Flow is a customer request and is based on your feedback.
As a light reading aid, the Flow is purely for guided reading to actively guide the eyes through the lines of text and benefit from the increased focus.

The same applies to the Bookhoover Booky. Satisfied users have already requested a smaller version as a reading aid for their children. This is precisely where the advantage of guided reading becomes apparent, in order to direct the attention of beginning readers and combine it in a playful way.
