*6.3. Future Perspective*

To overcome the technical challenges mentioned above, a number of future investigations are expected to focus on the following aspects:


body and human behaviors can be investigated for the further analysis. Research outputs may provide valuable reference for the studies of bionic robotics and for customized human intent estimation as well as smart recommendations in smart environments.

The above technical challenges may draw attention to the investigations of this field in the future, and the related studies about unobtrusive sensing, optimized sensing network and computing system, minor gesture and posture recognition, and further human body kinematics and behavior understanding are promising research topics that may add new features to HAR and create new opportunities of research and applications. Since HMI is a key attribute for the usability of information systems, HAR as a promising solution for the efficient and convenient interaction between human and inforamtion systems will play an important role in the future rich, sensing IoT world.
