Usability evaluation of the epoch multimodal user interface: designing 3d tangible interactionsUsability evaluation of the epoch multimodal user interface: designing 3d tangible interactions Πλήρης Δημοσίευση σε Συνέδριο Conference Full Paper 2015-11-012006enThis paper expands on the presentation of a methodology that provides a technology-enhanced exhibition of a cultural artefact through the use of a safe hybrid 2D/3D multimodal interface. Such tangible interactions are based on the integration of a 3DOF orientation tracker and information sensors with a 'Kromstaf' rapid prototype replica to provide tactile feedback. The multimodal interface allows the user to manipulate the object via physical gestures which, during evaluation, establish a profound level of virtual object presence and user satisfaction. If a user cannot manipulate the virtual object effectively many application specific tasks cannot be performed. This paper assesses the usability of the multimodal interface by comparing it with two input devices--the Magellan SpaceMouse, and a 'black box', which contains the same electronics as the multimodal interface but without the tactile feedback offered by the 'Kromstaf' replica. A complete human-centred usability evaluation was conducted utilizing task based measures in the form of memory recall investigations after exposure to the interface in conjunction with perceived presence and user satisfaction assessments. Fifty-four participants across three conditions (Kromstaf, space mouse and black box) took part in the evaluation.http://creativecommons.org/licenses/by/4.0/116-122ACM symposium on Virtual reality software and technologyProceedings of the ACM symposium on Virtual reality software and technology Mania Aikaterini Μανια Αικατερινη Panagiotis Petridis Daniel Pletinckx Martin White Association for Computing Machinery 3D video (Three-dimensional imaging) Three-dimensional video (Three-dimensional imaging) 3 d video three dimensional imaging 3d video three dimensional imaging three dimensional video three dimensional imaging
