The Spix.PDF app intends to increase the use of technical documentation on the shopfloor by the technicians and field operators. The goal is to help the blue-collars to get the relevant information, keeping their safety at work, and focus on their duty.

The motivation for this application results from the following difficulties of the shop-floor workers:

– Be focused on their tasks (hands and eyes free)
– Access to documents, procedures, drawings
– Get quickly to the relevant information
– Keep their gloves, helmet, and hear protections

To answer such need, the following functions are implemented (or will be) in the Spix.PDF app:

– Voice recognition capacity, in several languages,
– Browse in pages: number, sequence, previous, next,
– Inspect pages: up, down, left, right, again, …
– Manipulate the page: rotate, mode 2 pages, …
– Zoom in page: top, bottom, middle, zoom factor, …
– Recursive zoom: based on a virtual grid
– Quick search in a defined list : names, references, …


The functions and the area of application of the Spix.PDF app may change and evolve in the future, according to the customers’ needs and expectations. The first feedback and return from the industrial are of primary importance to drive the future development of the software.
