This report provides details of the embodiment design process, including analysis, ideation, development and validation, of a 3D hand scanner. 3D scanning, the process of creating a digital 3D model of a physical object, has opened up new possibilities for personalised products and improved diagnostics in healthcare. Since the hand poses unique challenges for 3D scanning, Delft University of Technology together with Vectory3 have invested in the development of a 3D hand scanner. This collaboration has already resulted in a technological proof of concept. However the technology needed to be brought to a user context. Through analysis, promising applications were identified in the areas of anthropometry, orthopaedics and rehabilitation. These applications and their contexts offered a framework of requirements for the embodiment design. Based on the various contexts, a simple to use product appearing somewhat medical while remaining colourful and friendly was envisioned. In-context observations and usage research were used to design a simple scanning workflow that fits all application areas. This workflow and its interactions were verified in subsequent usage research. Moreover, two studies, on light transmission and emission respectively, provide recommendations on the construction, materials and light source of the soft box. Around this, a dense internal component layout was developed allowing a compact design. Using a range of mood boards, sketches and models, the product’s outer appearance was shaped in line with the product vision. Both interaction and form were finally validated in usage research by means of a rapid working prototype. Once the core scanning technology is sufficiently developed it can be integrated into the embodiment design. It is recommended to then optimise the design and start the process of certification for use in medical environments. Moreover, it should be recognised that in order to deliver a strong product an additional design effort should focus on the post-scanning process, including data retrieval and (post-)processing.
