Since the introduction of shape changing interfaces, research in the field has contributed a number of taxonomies to classify shape changing interfaces according to different characteristics, including shape, interaction mapping, material, actuation, and information affordances, in an attempt to grasp the diversity of these interfaces in terms of design and information. However, to our knowledge there exists no classifications of input techniques that are used to deform shape changing interfaces through physical interaction. The interaction affordances provided by shape changing interfaces are important for interaction design and interaction mapping. The work presented here aims to analyse how deformable properties in shape changing interfaces are related to deformation techniques, in order to provide a first step towards the development of design guidelines for physical interaction with shape changing interfaces. The results of the study contribute an overview of interaction techniques based on the analysis of a set of 7 models with different deformable properties, each presented in 2D and 3D form.
