At softdevice, we have developed our own product, EKAKIO, a prototyping support tool that links graphic design software and hardware, with the aim of enabling users to easily extend their skills with little learning in situations where they are designing in areas in which they are not specialised. Now, on 25 November 2023, the ‘2023 Winter HCD Research Presentation Meeting’ was held at Kagoshima Women's Junior College, where a member of our company gave a poster presentation entitled ‘Development and practice of EKAKIO, a prototyping support tool that links graphic design software and input/output devices’. We also received an excellent poster award for this presentation.
