Kolibre Vadelma exemplifies the possibilities that exist with the open source software published by Kolibre. A talking book player can be built on various existing hardware platforms, including a Raspberry Pi-unit. Kolibre has published instructions on how to build a solution called Kolibre Vadelma (the finnish word for Raspberry). The source code is availabe at github.com/kolibre/meta-kolibre and the instructions on how to build the player is available in the wiki. The meta-kolibre layer uses the different Kolibre libraries to build the player…
Kolibre Vadelma navigation
To navigate in a book or in the menus with Kolibre Vadelma you will need a control panel, such as a keyboard or a number pad keyboard (numpad) with an USB interface. Kolibre Vadelma is by default designed to work with a numpad, but can also be configured to work with other control panels. And who knows? Perhaps speech recognition in the near future?
The keys on the numpad are arranged in pretty much the same manner as the keys on common DAISY players . The up, down, left, right arrow keys are used to switch navigation level and move back and forth in a publication. The number 5 key is used for play and pause.
