Virtual Mouse and Keyboard for Computer Interaction by Hand Gestures Using Machine Learning

/in /by

Human-computer interaction has changed since the advent of computer technology. Gestures are a useful way to communicate, and the Covid-19 era had an impact on us. Both the keyboard and the mouse are tools used to communicate with computers. Here, we’ve attempted to use hand gestures to interact with the mouse and keyboard. Eventually, get rid of the electronics. Consequently, use a virtual keyboard and your finger to move the mouse cursor. Using different hand gestures, actions like clicking, dragging, and typing data will be carried out.
A webcam is the IOT device required to accomplish this. The output from the camera will be displayed on the system’s screen so that the user can fine-tune it. We employ tools like Python, Media- Pipe, and Open-CV. The Media-Pipe library offers features that improve the model’s effectiveness and is particularly helpful in AI projects. The user will be able to move the computer cursor with various hand motions, type on the virtual keyboard while holding coloured caps or tapes, and left-click and drag objects. In this research, we suggest a hand gesture detection system for a natural human computer interface that can control a virtual mouse and keyboard.

Improving a Two-Way Interaction Customer Service Platform in Company X using AHP

/in /by

The Covid-19 Pandemic has accelerated mass digitalization in most human activities, including in the construction industry. As a response to the social restriction policy during the pandemic, customers and companies have preferred doing business online. Company X has already launched an online customer service platform that could be maximally used during the social restriction policy. This platform uses SST (Self-Service Technology) to let customers perform their service independently. However, the platform was ineffectively utilized due to a lack of sense of two-way interaction. The stakeholders suggested adding a new feature based on the customer’s aspirations and the company’s considerations. During the development, understanding the relationship between the user and the system must be learned through HCI (Human-Computer Interaction). This research is primarily focused on the factors that affect layout design. The method to obtain a new feature in this customer service platform is using Analytical Hierarchy Process (AHP) to minimize inconsistencies while considering the new features.
