Solution
Phase 1: Meetings, research, planning
We came up with an idea to build a useful application on windows phone. Our friends have a windows phone, and they would appreciate, if they had a German dictionary in his phone, because it had not existed. We did research by asking people if they know windows phone or own it. Also, we find out how many students are learning the German language and how knowledge of German was needed. We asked people in school and on Facebook. 60% owned or knew someone who is using a Windows phone. In Slovakia, that time was 3.14% of people using Windows phone. On this platform were only paid German-Slovak dictionaries, so we decided to create German-Slovak offline dictionary for free. Users are using our dictionary because it is the only free German-Slovak offline dictionary for Windows phone. Also, our dictionary contains translations from reliable sources, so users always get correct translation. The application is easy to use, and it is even offline.
Phase 2: Problem Solving, Design, and Coding
We built a database with 1000 words and basic application at first.
Definition of the Problem
How to store and give translations to the user effectively.
Problem and requirement analysis
Database with correct translations. Search algorithm to find translations. Show all matched words and their translations.
Problem Algorithm
User type some letters of a word. After the user clicks on the search button, our search algorithm will look for all words in our database that matches user input. When some words match, we print him the result, which contains the word and its translation.
Phase 3: Testing
We have to test all different kinds of user input, for example, diacritic. When the user uses or does not use diacritics, we give him the correct word, that he wants. We also were testing, if our search algorithm works precisely. When everything was solved, we give the app to our friend to test it, if everything works for him.
| User input | Search algorithm | Test user |
| Diacritics, part of word | Get correct translation | Everything works correctly |
Phase 4: Summary
German-Slovak offline dictionary for Windows phone is the most reliable dictionary for Windows phone users. We find out an efficient way of how to search for translations in our database based on user input. We tested everything that is used in our application.
