Students can communicate more easily using smartphones and the internet. Individuals with high social anxiety tend to choose smartphones or the internet to substitute real-life social communication; they show h
The invention discloses an attitude and position estimation method based on vision and inertia information. According to the method, by fusing vision and inertia information of an image, motion state information is saved and updated by virtue of an expanded kalman filter so as to calculate the ...
With the widespread adoption of smartphones, mobile phone addiction has increasingly gained prominence among Chinese college students, exerting a profound and detrimental impact on their learning engagement. This study employs self-determination theory as a framework to examine the mechanisms through which...
In recent years, the application of digital technologies for learning purposes is increasingly discussed as smartphones have become an integral part of students’ everyday life. These technologies are particularly promising in the so-called “transition-in” phase of the student lifecycle when first-...
Mobile devices such as laptops, personal digital assistants, and mobile phones have become a learning tool with great potential in both classrooms and outdoor learning. Although there have been qualitative analyses of the use of mobile devices in education, systematic quantitative analyses of the effe...
The navigation information obtained from the inertial system is featured with continuity, high data-updating rate, good short-term accuracy, and stability. The magnetic, angular rate, and gravity (MARG) sensors involved in MEMS technology have been widely used in smartphones for pedestrian inertial ...
which involves the flexible recording of both behavior and its determinants using smartphones in real-time situations [98]. Ambulatory assessment has been shown to be a reliable and valid method for assessing PA behavior and its determinants [99], and it provides more ecologically valid and contex...
Aiming at the attitude measurement based on MEMS (Micro Electromechanical Systems) inertial sensors, this article analyzes the limitations of traditional flight attitude estimate methods applied to MAV (Micro Aerial Vehicle) at first. Then, an extended Kalman filter (EKF) is deduced and constructed w...
Ear-Phone: A context-aware noise mapping using smartphones. Comput Sci Fac Publ Presentations. 2015;17:1–22. [25] Ventura R, Mallet V, Issarny V, Raverdy PG, Rebhi F. Estimation of urban noise with the assimilation of observations crowd- sensed by the mobile application Ambiciti; INTER...
The real-time attitude information of agricultural small unmanned aerial vehicle(UAV) is a key factor to the decision and operation for variable rate program in precision agriculture. A real-time attitude estimation system of agricultural small UAV is designed here which consists of a microprocessor ...
