Project Challenges

Usability and Accessibility for Field Engineers and Technicians
Interacting with different document formats and layout
Indexing, re-formatting the text in an unified way


Integrating with secured on site resources
Allocate engineers to site to get experience and constantly verify the design with field engineers.
Team is deployed both onsite and offshore to maintain continuous integration with target system .
Converting PDF, HTML and Word into intermediate HTML content.
• Innovative design to enable field engineers and technicians to quickly and easily access to targeted contents by categorizing, indexing, searching and bookmarking documents
• Converting and standardizing multiple document formats.
• Technologies: iOS 4,5, Objective C, PDF, Word, HTML Parsers


The application has been progressively deployed to various Airline divisions and  has received positive feedbacks from Field Engineers for the accessibility and convenience.
• Documents are now much more easily searched and accessed;
• Documents can be more frequently updated;
• The client reduced a lot of effort and cost from printing out and updating technical documents;
• Documents are synchronized to centralized and standardized;
