HCI can highly benefit from development of mobile context-aware applications. Therefore, three possible approaches to achieve this enhancement are listed as follows: first, considering the combination of multiple modalities such as eye movements, hand-based gestures and touch techniques in designing mobile context-aware applications. Second, further researches are required in the area such as context mapping, scheduling heuristic, information sharing, real-time data mining, wearable sensors, security policies, learning mechanism, virtual reality, and ontology modeling. Third, enhanced context-aware applications need to employ cheaper and lighter sensors (virtual and logical types), efficient ways to reduce power consumption, and innovative ways for information gathering from surroundings.
