TangiBookmark: Adhesive Stickers for Touch Screen Displays


A novel, sophisticated adhesive sticker and a related computer implemented method allow for the use of adhesive stickers with digital documents in the same way as used for paper-based documents.


Adhesive stickers consititute an efficient and easy to use tool to index documents. They can be labeled and easily relocated. However, they are so far not adapted for the use with electronic documents.

The use of known eletronic "bookmark" solutions for indexing electronic documents is complicated and not intuitiv for the unexperienced user. There is the intention to mimic the features of analog stickers by the use of software, but this is so far limited to particular kinds of electronic documents and it requires to much space of the screen.


Figure 1 illustrates the use of "TangiBookmarks" with a tablet computer. The user opens an electronic document and browses the pages. To index a certain text passage, the user places the inventive adhesive sticker at the border of the document displayed on the screen with touching the electronic contact section with at least one finger. By touching the sticker later on, the user can return to the indexed text passage. The sticker is made of paper, cardboard, plastics or any other appropriate material. The use of conductive materials such as copper enables the interaction between the sticker and the touch sensitive screen of a tablet computer or smartphone.


  • easy to use, intuitive
  • space-saving, in particular when used with small and medium displays
  • quick access to indexed text passages

Scope of application

  • tablet computers, smartphones, phablets, notebooks with a touch screen
  • indexing of text passages in electronic documents with a self-adhesive bookmark which can also be labelled


We are searching for a partner who is interested in licensing the technology aiming at an implementation, further development und commercialization of the solution.
