Only those who have experience in building map (2D/3D) & indoor navigation engine (online & offline) are encourage to apply. Develop navigation engine for iPhone & Android for indoor like mall and building. Welcome to co-develop with map expert. We will be using wifi & bluetooth embedded device that we develop as triangulation or a fix point reference point for navigation. Each box will be between 10m-20m space within the building proximity. Do not need step by step, turn by turn. Just need to know where the person is with smartphone and where the person is going within the mall. The experience search also included shopping experience.
