This article considers a further experimental demonstration of the equations of projectile motion employing the popular video-based motion modeling tool called Tracker. Using a downloaded video--of a free throw attempt by the NBA star Lebron James--from YouTube.com, the primary equations of projectile motion, together with a number of projectile…

Parents modulate their speech and their actions during infant-directed interactions, and these modulations facilitate infants' language and action learning, respectively. But do these behaviors and their benefits cross these modality boundaries? We investigated mothers' infant-directed speech and actions while they demonstrated the action-effects…

The rapid development of information and communication technologies has enabled the development of interfaces, which allow the recognition of the gestures and movements of the user. These interfaces, due to their affordable prices, are available to a wide range of users. They are called natural user interfaces (NUI). NUI are commonly used in game…

A Muscle-Computer Interface (muCI) is a human-machine system that uses electromyographic (EMG) signals to communicate with a computer. Surface EMG (sEMG) signals are currently used to command robotic devices, such as robotic arms and hands, and mobile robots, such as wheelchairs. These signals reflect the motor intention of a user before the…

The study investigates how learner experience with applications (apps) and how app types (native vs. non-native) influence performance in reading comprehension. Twenty-five high school students used different apps to read four texts. The students were asked to use the annotation feature of the apps to facilitate their reading. Ease of use,…
