**Preface to "Mobile Health Technologies for Ambient Assisted Living and Healthcare"**

The use of telemedicine and mobile devices is growing, and sensors might aid in creating creative solutions. Developing these solutions is crucial for monitoring senior citizens, lifestyles, and medical procedures.

This Special Issue's goal is to bring together academics and professionals in healthcare and medicine interested in using information and communication technologies (ICT) to serve people with special needs. The development of assistive technology for various users to follow sports and other activities is strongly tied to this study area. Data protection is crucial, and the development of these solutions for medical uses should be verified. The security and privacy of the information may be tied to other recognized research projects for their acceptability. ICT research has considerably improved quality of life and fully assimilated all citizens into society through medical rehabilitation and assistive technology. The technologies and research fields that influence medical informatics include databases, networking, graphical user interfaces, data mining, machine learning, intelligent decision support systems, and specialized programming languages.

Because mobile devices are commonly used for several everyday chores and are equipped with sensors that monitor various physical and physiological indicators, it is crucial to encourage the development of m-Health and e-Health solutions for healthcare practitioners. In this area, several solutions are now being developed. In addition, these can collaborate with emerging technologies for social assistance while enhancing life quality.

This book presents a collection of 11 studies related to the use of technological equipment for an improvement in quality of life, establishing its relation with other subjects. The editor would like to thank the authors for their interest in submission to this Special Issue, the reviewers that collaborated with the different reviews, the different people that helped in the promotion of this Special Issue, and the different institutions involved. This work is also funded by FCT/MEC through national funds and, when applicable, is co-funded by the FEDER-PT2020 partnership agreement under the project UIDB/50008/2020.
