        <p>The emergence of affordable consumer drones promises new perspectives for interacting with the physical world around us. Affordable, accessible, and easy to operate drones have the potential to overcome geographic boundaries between users living in different locations and subsequently foster connectedness. Yet, the design space of using drones to facilitate social interactions beyond geographic boundaries is still underexplored. In this position paper, we envision principles derived from the concept of lucid engagement and the psychological need for connectedness to explore how drones can mediate social interactions. We introduce our design concept and discuss it based on a specific application scenario. We discuss the opportunities and challenges related to our interaction concept. Finally, we outline next steps for future research.</p>

      <title>Introduction and Background</title>
      <p>In recent years drones have become affordable for the
average consumer. Simultaneously, the field of
HumanComputer Interaction (HCI) started to explore the design
space of Human-Drone Interaction.</p>
      <p>
        Broader selections of different drone models and sizes and
the availability of automation frameworks [
        <xref ref-type="bibr" rid="ref2">8</xref>
        ] foster the
creation of new concepts and prototyping of novel drone based
user interfaces.
      </p>
      <p>
        Studies have shown that ‘flying user interfaces’ [
        <xref ref-type="bibr" rid="ref1">6</xref>
        ] can be
used, among other things, to interact with the world around
us, such as to provide assistance [2, 3] and as a means to
interact with other people [
        <xref ref-type="bibr" rid="ref12 ref13">19, 18</xref>
        ]. Consequently, drones
have the potential to significantly shape our communication
landscape [5]. However, drones have mainly been used to
foster utilitarian activities. There has been little exploration
of their potential for more ephemeral interaction qualities
going beyond facilitating communication, such as fostering
connectedness between humans. A sense of social
connectedness includes feeling connected to the world around
you, being part of the society, and feeling close to other
people [
        <xref ref-type="bibr" rid="ref9">15</xref>
        ].
      </p>
      <p>
        Drones also have inherent characteristics which make them
particularly suitable for supporting playful, ludic interactions.
They are transportable, easy to operate, and they also
address human fascination with flying objects. Ludic activities
describe playful activities driven by curiosity, such as
geographic exploration [7]. However, even though drones have
been used as toys (e.g. [
        <xref ref-type="bibr" rid="ref4">10</xref>
        ]), as hovering touchable objects
[
        <xref ref-type="bibr" rid="ref6">12</xref>
        ] (e.g. for VR [
        <xref ref-type="bibr" rid="ref3">9, 1</xref>
        ]), and to support communication [
        <xref ref-type="bibr" rid="ref13">19</xref>
        ],
the design space of drones to facilitate social interaction,
exploration, and ludic engagement is still underexplored.
Hence, one of the aims of this position paper is to envision
the potential of drones to support social connectedness
through geographic exploration of spatially separated users.
In contrast to previous work that explored drones as
digital companions (e.g. to accompany the user on their way
home) [
        <xref ref-type="bibr" rid="ref5 ref7 ref8">11, 13, 14</xref>
        ], we envision integrating the digital
companion qualities of the drone with the human companion
qualities to facilitate connectedness through shared
geographic exploration.

      <title>MaDrone: Facilitating Connectedness</title>
      <p>With MaDrone, we have identified opportunities for
connectedness that go beyond face-to-face video communication,
as detailed below.</p>
      <p>
        Connecting people MaDrone allows people, e.g. friends
and family, to connect remotely, i.e. across geographic
borders. The possibility to share visual content over long
distances supports social connectedness among users,
especially when they live in different geographic regions.
Providing a Bird’s Eye View Contrary to prevalent video
communication, drones can provide a feeling of
exploring through the bird’s eye view, allowing for ludic
engagement [7]. Through directly influencing the visual content that
is created, we create a feeling of agency for the user [
        <xref ref-type="bibr" rid="ref10">16</xref>
        ].
Increased immersion can also be obtained through
interactive arrangement simulating the natural way of conduct.
Enabling the remote participant to perceive both the presence
of the other person and their surroundings may enhance
the social benefits of telepresence experience.
      </p>
      <p>
        Negotiation of Control MaDrone allows users to
negotiate and share control (cf. Fig. 1) over the video content.
Previous work has already showed that shared interactive
systems (e.g. tabletops) that facilitate interaction between
co-located users can potentially lead to new communication
mechanisms [
        <xref ref-type="bibr" rid="ref11">17</xref>
        ]. Here, we aim to explore how novel
interactive systems (i.e. drones) can be used for geographically
distributed users.
      </p>
      <p>Connectedness beyond Social Bonds By building an
understanding of the living environment of another and
sharing the experience of exploring an area, MaDrone
creates a feeling of social connectedness. In addition, actively
exploring remote geographic areas supports building an
understanding of other living contexts and subsequently
fosters connectedness that goes beyond social bonds. It
allows connectedness to nature and society, and creates a
feeling of ‘being there’.</p>

      <title>Scenario</title>
      <p>Figure 1 illustrates the concept of MaDrone in the form of a
storyboard. The storyboard describes communication and
negotiation between Lisa and Max, as well as the
interaction with a drone located with Max.</p>
      <p>Initially, Max invites Lisa to explore the city with him. Lisa
is excited about this opportunity. When she accepts the
invitation, Max decides to guide Lisa through a nearby park.
He instructs the drone to follow him.</p>
      <p>Lisa enjoys exploring the park with Max. She follows his
tour on her computer screen. Later, she requests to take
control over the drone. Max receives her request and
accepts it.</p>
      <p>Lisa can now steer the drone herself and even focus the
camera on scenery that she wants to explore. She could
control the drone with her keyboard and mouse, but decides
to connect a joystick that she owns. Finally, when Max
decides to return home, he instructs MaDrone to return.</p>
    </sec>
    <sec id="sec-5">
      <title>Discussion and Next Steps</title>
      <p>Adding more users to a shared drone experience produces
challenges and opportunities. Future interfaces where
multiple users control a drone will need to include the means
to negotiate navigation. While past work explored different
navigation modes, such as gestural interaction with flying
drones and cultural influences on human-drone interaction
techniques [4], these traditionally assume that the drone
has a single pilot. In contrast, one of the main challenges
that arise from our vision is facilitating a positive experience
of the navigation negotiation in a dyad or a group of more
than two people.</p>
      <p>Another interaction design challenge stemming from our
vision is designing for the domestication of drones so that
they can become everyday objects, possibly fostering
ludic engagement. As users are often overwhelmed with the
initial perceived complexity of operating a drone or simply
scared of being hit, future designs should enable simplified
control so that a variety of audiences can have access to
the drone’s social features.</p>

      <title>Conclusion</title>
      <p>In this position paper, we shared our vision of how drones
can be used to facilitate social interaction through enabling
exploring geographical location together. We showed how
shared drone interaction can foster social connectedness
between remote users and thus cater to their social needs.</p>
      <p>We illustrated our vision with a scenario and a storyboard.</p>
      <p>The concept presented here illustrates a key challenge to
Human-Computer Interaction: designing interfaces that
enable multiple users to collaboratively use drones for social
exploration. Further, our work suggests that drones can
become a medium for ludic interaction.</p>
