- Proficient ambient intelligence based on the wisely selection of data sources in heterogeneous environmentsPublication . Melo, David Filipe Quinta; Pombo, Nuno Gonçalo Coelho Costa; Xu, LinaNowadays society tends to be more and more technologically evolved, with that a lot of personal information is shared with computational systems through online records; microphones that perform voice recognition in which it is processed remotely; application of filters on person portraits or recognition of the age at which the image is saved on a server to improve the standard of an Artificial Intelligence (AI). The devices we currently interact with end up compiling information about our consumption habits, routines, collected photographs, videos or personal content. Sometimes exposing our privacy to third parties, it is not noticeable where that data is been saved, or that is being stored. And if we could have a simpler device to perform some tasks, in which there was no camera, microphone or storage. No personal data will be processed locally or remotely, so the regulation European Union (EU) law on data protection and privacy, General Data Protection Regulation (GDPR), will not affect this kind of device. Furthermore, if a device of this nature was located in a public place, there would be no need for any requirement, consent or authorization to the intervening users or only those who approach the device, because would not differentiate the user or even recognize him, since the collection of gesture commands is performed through non-evasive sensors. Recently the world was surprised by the cases of a new coronavirus which caused a pandemic on a planetary scale. New rules had to be applied, to the way we interact with objects in order not to spread the disease. It was created a prototype discriminated in this study, using a grid of ultrasonic sensors, capable of recognize trained gestures. This interaction can be made from a distance of the prototype, and do not require contact, in which it solves a human interaction with the computer avoiding that the user has to use the touch on a component, thus avoiding the contagion of Corona virus disease of 2019 (COVID-19). The early stage results evidence that the proposed system is suitable to create a new input type of Human Interface Device (HID), and may replace devices as a remote control of television, to a new way to interact with information panels in public places, like a shopping mall, airports, train and bus stations.
