DESIGNING MOBILE MULTIMODAL ARTEFACTS
Users' characteristics and their different mobility stages sometimes reduce or eliminate their capability to perform paper-based activities. The support of such activities and their extension through the utilization of non paper-based modalities introduces new perspectives on their accomplishment. We introduce mobile multimodal artefacts and an artefact framework as a solution to this problem. We briefly explain the main tools of this framework and detail two versions of the multimodal artefact manipulation tool: a visual centred and eye-free version. The design and evaluation process of the tool is presented including several usability tests.
