Power Efficient Smart Home with Voice Assistant

An Accessible Smart Home Based on Integrated Multimodal Interaction

“…Regarding home assistants, while many authors focused on a specific group of people, such as the elderly and/or disabled [ 37 , 38 , 39 , 40 , 43 , 63 ], our assistant is meant to be accessible to all home inhabitants, from younger to older, with or without temporary/permanent limitations. Furthermore, most works mainly aim at device control and/or home automation [ 38 , 43 , 63 , 64 , 65 ]. In contrast, our system goes beyond simple control or automation, by allowing obtaining rich relevant information on the home and its devices.…”

“…In general, few or no details are given in the relevant literature about the structuring and handling of data regarding the home and all its devices and appliances. Some works just mention the use of a database [ 34 , 36 , 37 , 44 , 64 ]. Only two contributions adopted a semantic approach similar to ours [ 49 , 66 ], by using an ontology, although none of them include an assistant.…”

“…Only two contributions adopted a semantic approach similar to ours [ 49 , 66 ], by using an ontology, although none of them include an assistant. As for system initiative, the few examples found in the literature are limited to a single type of alert: fire alarm according to information provided by flame and temperature sensors [ 64 ]; use of a light sensor to inform the blind users about day/night [ 40 ]; alert when an intruder is detected in the context of surveillance [ 39 ]; alert when a person with dementia leaves food in the cooker longer than needed [ 37 ].…”

“…An outlier is the conversational assistant proposed by Salvi and coworkers [ 36 ], which relied on Google’s Dialogflow platform. Other authors used commercially available assistants, such as Google Assistant [ 38 , 65 ] and Alexa [ 64 ]. In regard to the language(s) covered by the assistants proposed in the literature, the most common is English [ 34 , 35 , 36 , 37 , 38 , 39 , 64 ].…”

Only a few support different languages, such as Spanish [ 43 ], Indonesian [ 63 ], or Bengali [ 40 ].…”
