-In the previous chapters I either focused on output and the sense of touch, or input and the motor ability.
-The models I described in these chapters corresponded to my initial vision of interactive systems with separate input and output pipelines.
-I showed interesting contributions made with this vision.
-It is relevant in notification systems in which input is limited anyway.
-But even in these chapters the sensorimotor loop was already there.
-How could it be different?
-In this chapter I wanted to describe how thinkg with the sensorimotor loop in mind changed the way I approach HCI research.
-I described the foundations of the field, and their connections to many other research domains.
-Of course, each of these notions were individually studied for decades since their discovery, and they are still studied and extended today.

+%The models I described in these chapters corresponded to my initial vision of interactive systems with separate input and output pipelines.
+%I showed interesting contributions made with this vision.

+%But even in these chapters the sensorimotor loop was already there.
+%How could it be different?
+This document presents the evolution of my vision of Human-Computer Interaction as I practice it in my research.
+The first two chapters describe my early vision that either focuses on output and the sense of touch, or input and the motor ability.
+The third chapter describes the limits of this approach, and how the sensorimotor loop combines these two approaches to form a sum that worth more than its parts.
+However, each chapter presents useful lessons learned from years of research.
+
+\refchap{chap:output} was the connection with my Ph.D., which essentially focused on haptic feedback.
+I used haptics essentially to encode information with Tactons that users mostly received as notifications.
+My work focused on the encoding for the system side and interpretation on the human side.
+In this chapter, I presented work in which I studied other parts of the pipeline, in particular the device level on the system side, and psychophysics on the human side.
+My vision of this work evolved thanks to collaborations with researchers of other domains, like cognitive sciences, electronics, and material sciences.
+
+After working almost exclusively on haptic output, I got interested in input techniques as well.
+The \refchap{chap:input} describes the symmetry between input and output systems.
+The difference is who between the user and the system stimulates the other.
+Interestingly, while systems have many ways to stimulate human senses (\eg visual, audio, or haptic cues), humans essentially stimulate systems with gestures.
+However, the richness of the gestures we can perform and their properties we can measure is an endless source of input solutions.
+
+In \refchap{chap:loop}, I wanted to describe how thinking with the sensorimotor loop in mind changed the way I approach HCI research.
+I described the foundations of the field and their connections to many other research domains.
+Of course, each of these notions was individually studied for decades since their discovery, and they are still studied and extended today.
But instead of focusing on a precise notion, I rather wanted to take this opportunity to look at the whole picture.
It felt like a giant mind puzzle because all these notions are connected.
-It reflects the systemic approach in my research, and life in general.
-I like to understand all the sides of a problem rather than focusing on a specific aspect.
+It reflects the systemic and interdisciplinary approach in my research and life in general.
+%I like to understand all the sides of a problem rather than focusing on a specific aspect.
+Interdisciplinarity is certainly the most exciting aspect of Human-Computer Interaction to me.
+The design, implementation, and evaluation of interactive systems require knowledge of the users, their biology, their cognition, their behavior, and knowledge about technologies, their mechanics, electronics, and software.
+Many researchers are highly specialized in one of these aspects.
+I rather prefer a systematic approach that consists in studying all the angles of a research problem.
+It is a difficult practice because each research community has its own literature, methodologies, and practices.
+But it is also an infinite source of ideas to push my research in new directions.
+%In this document, I discuss the critical role of the sensorimotor loop for interactive systems, and its numerous connections to many research domains.
+%It is the notion that connects the results of these research communities

+\section*{Future work}
+In \refchap{chap:loop} I described interaction with three components: users and their sensorimotor loop, systems and their execution loop, and a shared environment.
+Each of these components is a source of research questions.
+So far, my research did not focus on any category of users, technology, or interaction context.
+I rather had a horizontal approach consisting in searching for appropriate solutions to any problem for any user.
+In my future research, I would like to focus on particular contexts, in order to favor incremental research and facilitate transfer of research results to the industry.

+\paragraph{Interaction in Metaverses}
+There is an increased interest in immersive virtual environments over the past few years.
+The idea of metaverses was already there decades ago in popular culture \cite{gibson84,stephenson92,cline11}.
+The technology also emerged decades ago~\cite{sutherland65,sutherland68}.
+However, like every technology, it required time and a lot of research to become mainstream.
+The availability of consumer-grade VR headsets over the last few years fostered research on interaction in immersive virtual environments.
+I described the contributions we made on this topic in \refchap{chap:input} and \refchap{chap:loop}.
+It is however still unclear what metaverses will be like \cite{guitton22}.
+Some see it as a shopping mall, others as a social network, a gaming platform, or a classroom.
+Whatever it will be, immersive virtual environments challenge our senses and abilities.
+Without the constraints of the physical world, there are many new possibilities to leverage the sensorimotor loop.
+\paragraph{Interaction in Space}
-\section{Future work}
+Humans will return to the Moon in the upcoming years with the ambition to keep a sustained presence at the end of the decade~\cite{smith20}.
+The objective is to prepare for manned missions to Mars.
+This ambition requires developping space activities to a scale never seen before.
+It will involve more humans and robots in space and mission control on Earth.
+%It will not only involve space agencies, but also private companies.
+Space challenges many aspects we take for granted on Earth.
+Entities in space live in a completely different physical environment, for instance with low gravity.
+And the interaction between entities on earth and in space suffers from communication constraints, like latency, limited bandwidth, and connection availability.
+There are therefore many open research questions related to the effects of these conditions on the sensorimotor loop.
