Describe how the following industries use motion input: entertainment, military, athletics, and medical.

What will be an ideal response?

Entertainment: Motion-sensing game controllers enable a user to guide on-screen elements by moving a handheld input device through the air. Examples include handheld devices that enable gamers to use sweeping arm movements to simulate sports activities, such as a golf swing, balance boards that judge stability and motion when holding yoga poses, and remote control attachments, such as a steering wheel used to guide a car along a race course. Some controllers track peripheral motion within a specific area. With these devices, users can move their finger to draw or move their whole body to dance or exercise. Some use a device that can track small finger gestures, enabling users to be more precise in their movements. Facial motion capture converts people's facial movements into a digital format while they talk, smile, and more. Animators, for example, use the digital data to simulate facial movements to create realistic gaming avatars or computer-generated characters in movies. Facial movements, however, are more subtle and difficult to detect. Thus, the technology used for capturing facial motions requires more precision and a higher resolution than that required by gaming devices.?Military: Military uses of motion input include training, such as flight simulation or weapon usage. To ensure safety, trainees maneuver a helicopter or other device using motion input from a remote location. Motion input also aids in physical rehabilitation for wounded soldiers by providing a method for conducting physical therapy exercises outside of a military hospital. Another use of motion input is to assist in recovery from post-traumatic stress disorder. Sufferers of this ailment can use avatars and simulators to work through scenarios in a comfortable environment.?Athletics: Coaches and sports trainers use motion input to improve athletes' performance and to correct inefficient or injury-causing motions. Analyzing the arc of a pitcher's arm, and factoring the speed of the motion and the trajectory of the ball, can help improve a pitcher's accuracy and speed. Combining the athlete's motion input with complex algorithms can pinpoint areas in which the athlete can improve.?Medical Field: The medical field also uses motion input for training. For example, surgeons can practice new technologies in a simulated environment. Using motion input that enhances movements, surgeons also can operate less invasively. Surgeons even operate remotely, enabling experts to manipulate surgical devices and share their expertise to save lives around the world. Sports medicine specialists use motion input to assess injuries, determine treatment, and assist in physical therapy.
