Internship: Design Exploration of 2.5D Mobile Display


2.5D displays or pin-based shape displays can physicalize digital information by moving an array of pins in z-axis [1, 2, 3]. They can change shape on demand, providing either flat graphical user interfaces or display 3D information in the real world. 2.5D displays let users directly manipulate them. However, the 2.5D displays largely rely on linear actuators such as motors, which require a large space beneath the interaction space. In this research project, we aim to explore different folding mechanisms, such as [4], to implement a 2.5D display that can fit in a mobile phone-sized volume.

Research Question

What is the optimal design and material for a single pin in an array making such 2.5D display? We will explore many origami folding designs (e.g., [4]) and materials and evaluate them. We will discuss the evaluation criteria including: travel distance of a pin, robustness, easiness of actuation, modularity and adaptability to differently shaped surfaces.

Required Skills and Experiences

Objective of the Internship

During the internship, the student is expected to:

For all these steps, previous work, material and experience from both supervisors will help to get a start and improve the student’s work.


Please send your CV and academic transcript to We will restart reviewing the applications mid-December, and you can apply until the position is filled.

If you have any questions, don’t hesitate to contact us.
