Mobile transformers are mobile device products with an innovative and/or adaptive form factor that users can modify dynamically, based on specific context and needs. Some products are still at the conceptual model stage (for example, the Nokia Morph); others are already commercially available. Modu’s Modu Mobile uses a modular, Lego-like approach, based on building blocks, to assemble and create the most appropriate form factor for a user at a given time. Nokia’s Morph instead adopts innovative materials (based on nanotechnologies) that enable flexible, foldable, stretchable designs — allowing users to transform their mobile devices into radically different shapes.
