Internship on Skill Transfer and Tangible User Interaction
Skill Transfer Across the Scales of a Tangible User Interface
Typical elements of Tangible user interfaces (TUIs) include physical knobs, sliders and buttons. TUIs are widespread in users’ everyday and professional life. Example applications of use are airplane cockpits, sound and light mixing consoles, color grading consoles, car controls, etc. Current TUIs exist in different sizes. For instance, sliders are manufactured in a range from 1cm to 10cm. Recent advances allow to imagine TUIs that can adapt their size according to the users’ needs and the available space. As a consequence, users have to rescale their sensori-motor abilities or skills to achieve similar tasks using TUIs varying in size.
As a person uses an interface, s/he learns new motor skills to become an expert user of the interface. If the size of the interface can vary across situations of use, how well will the users’ skills acquired with a particular scale transfer to a smaller or larger scale? Some parameters such as the properties of the task may also affect transfer. A better knowledge of these parameters will help designers improving TUIs.
Filling in the gaps of current knowledge about users’ adaptation is essential to reshape the User Interfaces of tomorrow. In the critical domains where TUIs are widely and successfully used (cockpit, cinema, hospitals, etc.), the lack of skills’ transfer could costs money, usability, mobility and, sometimes, even security.
The ability to learn and adapt sensori-motor skills to different situations is extensively investigated in motor control literature, e.g. . This research field is providing experimental paradigms and theoretical frameworks that can help designers to evaluate and improve Human Computer Interaction (HCI) . The current project is at the crossroad of Motor Control (Cognitive Sciences) and HCI (Computer Science). Our approach will be based on recent studies of dynamics learning across changes in movement amplitude  and studies of users’ performance with a shape-changing tangible slider .

Objectives of the internship
During the 5 months time of the project (February to June 2016), the student is expected to:
• Review related work in both motor control and human-computer interaction fields,
• Design an experiment assessing the skill transfer across the scales of one or two typical tangible widget (e.g., a slider and/or a knob)
• Make the tangible widgets using local FabLabs like FabMSTIC (http://fabmstic.liglab.fr),
• Track the tangible widgets with the local high performance Optitrack system (http://www.optitrack.com),
• 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.
The internship requires good coding skills. Statistics skills are a plus.
