A participatory design approach to information architecture design for children

A design process that involves the participation of children should effectively elicit the needs of child users by considering characteristics such as their age-appropriate levels of cognitive ability, shyness, language skills, and motor-sensory capabilities. Since the 1960s, a variety of methods and guidelines have emerged specialising in children. Participatory design deals with the problem of enabling users to participate in the design process and with the task of generating ideas by means of generative toolkits and workshops. Hence, participatory design enables designers to look at problems from a childs standpoint and, simultaneously, deal with childhood traits such as shyness and immature language skills. This paper introduces two participatory design toolkits: namely Info Block and Info Tree. These toolkits enable users to build information architecture (IA) that can, firstly, reflect their cognitive characteristics and, secondly, elicit user needs with respect to the information architecture design of childrens websites. In a case study, the toolkits were used to evaluate the usability of the Yahoo!® Kids (Korea) directory. The results show that the information architecture of children differs from that of adults in depth, breadth, and clarity of contents and logicality. Finally, suggestions are made to improve the usability of childrens websites.

Designing collaborative services on the digital platform

This paper is based on an on-going doctoral research on service design for social innovation and sustainability. It introduces the notion of collaborative service and discusses its two dimensions in relation to ICT (information communication technologies). Case studies of collaborative service on the digital platform were conducted to identify the role of ICT in developing and diffusing collaborative service and a part of the result is introduced.

COVALENT, a method for co-designing value exchange in community-centred design

Abstract It is challenging to design for mutually beneficial relationships in a multi-actor service system when these actors have diverse and conflicting interests, and lack usable methods and tools that support the design process. This study introduces a novel method for co-designing value exchange (COVALENT). COVALENT integrates the value analysis model, co-design strategy and service design tools, to support the conceptualisation of reciprocal value exchanges based on the analysis of and matching between, stakeholders’ needs and resources. Its perceived effectiveness was validated through application to the development of community business models in Ulsan, South Korea. This study contributes to the knowledge of co-design by providing a method for co-designing services that aim to achieve reciprocal value exchanges in the context of community-centred design and by discussing the effectiveness of that method as perceived by users.
