Internship on investigating the size of small robots for user interaction

Investigating the size of small robots for user interaction

Background


Shape-changing user interfaces (UI) have emerged as a new way to interact with computers, using dynamic changes in a device’s physical shape for input and output. The prototyping of shape-changing UI, let alone their development, is a consensual grand challenge in the Human-Computer Interaction (HCI) community [1]. Programmable matter is a promising way to implement future shape-changing user interfaces. Programmable matter is defined here as a modular robot composed of a huge number of mm-scale, stand-alone, spherical and detachable robots that can rearrange themselves in the 3D space (http://projects.femto-st.fr/programmable-matter/), allowing for as many shapes as play-doh.

Research question


What is the optimal size for molecular robots from the user viewpoint? We will evaluate the users’ perception of different resolution of shape-changing interfaces made of small-scale robots to find the optimal size resolution. While current molecular robots can be used to implement low-resolution interfaces, higher resolution will be obtain through mock-ups of molecules of smaller sizes and today’s tangible UI.

Importance


Spending effort in developing extremely tiny robots might be a waste of time from the user viewpoint as users might not be able to perceive the difference.

References


The internship will address the challenge of introducing the interaction with the user with modular robots. This challenge has been barely addressed so far both in the fields of HCI and robotics [2,3,4].

Objectives of the internship


During the internship, the student is expected to:
• Review related work in the robotics and human-computer interaction fields,
• Build comparable prototypes at different relevant resolution,
• Design an experiment assessing the users’ perception of the different resolutions for different tasks,
• Implement the experiment’s software,
• Conduct the experiment,
• Analyze the results of the experiment,
• Write and defend her/his thesis.
For all these steps, previous work, material and experience from both supervisors will help to get a start and improve the student’s work.

Applicants


The internship requires making, coding and statistics skills. If you feel unsure about your skills but are interested in the topic, contact us.
