Computer Interaction

The interaction technology in general is inseparable from the rapid development of Human-Computer Interaction technology or Human and Computer Interaction. Human and computer mouse interactions are called Virtual Mouse. Virtual mouse is designed for users to be able to interact directly with computers without using input devices such as conventional mice but using their hands as driving objects or using other media such as colors. In this research, testing is done on how to track an object that moves in order to do the mouse by using an intermediary in the form of an image processing-based webcam video that is taken in real-time using object tracking in the form of three color variables arranged based on RGB composition using the optical flow method in detecting its movement. Based on research that has been carried out as a whole the color object used as a pointer controller or mouse with the optical flow method can be detected properly in every condition.

Computer Interaction

This study evaluates and compares the suitability for child–computer interaction (CCI, the branch within human–computer interaction focused on interactive computer systems for children) of two devices: a standard computer mouse and the ENLAZA interface, a head mouse that measures the user’s head posture using an inertial sensor. A multidirectional pointing task was used to assess the motor performance and the users’ ability to learn such a task. The evaluation was based on the interpretation of the metrics derived from Fitts’ law. Ten children aged between 6 and 8 participated in this study. Participants performed a series of pre- and post-training tests for both input devices. After the experiments, data were analyzed and statistically compared. The results show that Fitts’ law can be used to detect changes in the learning process and assess the level of psychomotor development (by comparing the performance of adults and children). In addition, meaningful differences between the fine motor control (hand) and the gross motor control (head) were found by comparing the results of the interaction using the two devices. These findings suggest that Fitts’ law metrics offer a reliable and objective way of measuring the progress of physical training or therapy.

Computer Development

Technological developments in the field of computers getting faster requires the ability of each person to be able to follow the progress of computer development. Computer vision applications is an application that allows the computer to have the ability to be able to capture and understand the data, such as image and make decisions based on the data from the real object movement that was in front of the webcam and then the data obtained is processed in accordance with user needs. Digital image of a real object is captured by a webcam can be done in various ways making objects. In this research, object retrieval by utilizing activity in this object is that caught on webcam pen is through the form and motion of objects. Once an object is detected then the object is to move the cursor on a computer. To be able to perform image processing, this application uses OpenCV components. Meanwhile, to be able to perform tracking of the cursor object using optical flow method. Cursor moves when the pen has a rectangular sides and parallel to the pen position frame of grabber.
