概括
人们可以根据视觉反来调整动作,即使不看自己的手. 对视觉目标或光标变化的反应在运动的后期更为强烈,对目标和光标都类似.
科学领域:
- 发动机控制器 发动机控制器
- 人类的感官运动适应.
- 视觉运动转换的变化
背景情况:
- 个人通常在达到运动时固定在目标上,以持续更新其位置和运动.
- 然而,关于手的位置的视觉信息仍然可以用于更新运动判断,即使没有对手的直接视觉关注.
研究的目的:
- 调查视觉干扰对运动反应的活力如何取决于运动中的时间.
- 为了比较对目标位置中扰动的反应与手部位置 (光标) 的视觉反中扰动的反应.
主要方法:

7.5K
Velocity and position can be calculated from the known function of acceleration as a function of time. The total area under the acceleration-time graph and the velocity-time graph gives the change in velocity and position, respectively. In the case of an airplane, its acceleration is tracked using the inertial navigation system. The pilot provides the input of the airplane's initial position and velocity before takeoff. The inertial navigation system then uses the acceleration data to...

Consider a crane whose telescopic boom rotates with an angular velocity of 0.04 rad/s and angular acceleration of 0.02 rad/s2. Along with the rotation, the boom also extends linearly with a uniform speed of 5 m/s. The extension of the boom is measured at point D, which is measured with respect to the fixed point C on the other end of the boom. For the given instant, the distance between points C and D is 60 meters.
Here, in order to determine the magnitude of velocity and acceleration for point...

01:14Design Example: Resistive Touchscreen
358
A device engineer plays a crucial role in designing user interfaces for mobile devices. One such interface is the resistive touchscreen, which fundamentally consists of two metallic layers: a flexible upper layer and a rigid lower layer, separated by a narrow gap. The high resistance between these two layers is a key characteristic of this design.
When a user touches the screen, the two layers make contact at a specific point known as the touchpoint. This contact reduces the resistance between...
