Question first: Passive interaction model for gathering experience and knowledge from the elderly

Abstract

We propose the "Question First" interaction model, which aims to reduce the barriers to accessing online mobile information transmission for the elderly and aggregate their useful experience and knowledge for younger generations. "Question First" helps elderly users to transfer their knowledge or experiences by simply answering questions through conventional mobile terminals. The proposed interaction model is based on extending conventional interaction modes of phone calls and em ails, helping elderly users become fam iliar with social networking, without the requirement of learning to use social networking service interfaces. Ultimately, we aim to expand the social participation of the elderly in both online communication and online work such as crowdsourcing. We report the results of a two-week user study on the crowdsourcing of participants' experience and knowledge through online communication, and analyze the information obtained to evaluate the efficiency of this interaction model by extracting features of each participant's knowledge and experience via the proposed method.
