ContactJS -- A Cross-Platform Context Detection Framework

Mobile devices like smartphones and tablet computers made it possible to access educational offers spatially and temporally unbounded. However, learners have different prior knowledge and preferences, and are in different situations. Contextual information can be used to adapt educational offers to the learners´ individual needs and characteristics. When it comes to the detection of such information a challenge however is to address the heterogeneous landscape of devices and operating systems (and thus programming languages) that learners are using. To meet this challenge this paper presents a cross-platform context detection framework.
