Machine learning is improving the state of the art in many fields of technology. This enables new paradigms in day-to-day tasks that will gradually make a shift in people’s lives. One of these emerging fields is visual based human-computer interaction (HCI), which offers huge potential. Many people are not able to use common human-computer interface devices, such as the mouse or keyboard. It is our hope that this emerging field will enable more efficient HCI methods, gradually improving the way we interact with computers.

In this context we have recently released Lima, a Microsoft Windows application which allows control of the mouse cursor by detected head movement, facial expressions and voice commands using a standard webcam. There is room for improvement, and more efficient visual based control methods and interactive functionalities to come. The app is now freely available for Windows 10 and 11 through the Microsoft Store, with some premium functionalities.

We believe this application can make a positive difference in the lives of many people who face challenges in using a mouse or keyboard. We hope you will give Lima a try and let us know what you think. We would love to hear your feedback and suggestions on how to improve the app and make it more useful. For that, please feel free to contact us at fidel.echevarria@outlook.com.

Thank you for your support and interest in Lima. Together, we can create a more accessible and equitable world for everyone.🌎
