Methods and tools for human centered ICT: from human values to real-life innovation | Mulder, van Waart, Leurs & Choenni

Presentatie titel Rotterdam, 00 januari 2007 D-CIS Human Factors day 2008, Delft 10 September 2008

research in the field of human-computer interaction, intelligent environments and exploiting these technologies to understand user behavior and user experience as well as informing the design of innovative technology and interactive media.

User centered design An approach that supports the entire development process with user-centered activities in order to create applications which are easy to use and have added value to the intended users analysis design and requirements planning real-life evaluation human values

In this, the emphasis is on designing for the real world and therefore completing every stage in human-centered design, starting from eliciting (latent) user needs to implement innovative technology and interactive media in a real-life context of use. In this human centered perspective, co-creation and the involvement of users in the design, development, and evaluation of innovative technologies and interactive media is crucial.

Designing for the real-world In all stages of human centered design, methods are required to elicit information from and about users that are not as such available. It concerns both methods to obtain information about needs, desires, capabilities and limitations of people in an early stage of the design process, and methods for validating/evaluating the design in later stages of the co-creation process.

Method and tools

Human-centered ICT toolkit A guide to easily get an overview and understanding of user centered design and evaluation methods for interactive software and media. An overview of methods, tools and techniques available in literature. An overview of methods, tools and techniques learned and applied in CMI courses An overview of techniques and tools being employed in different IT- and media enhanced sectors (i.e., student projects).

Creative research tools and sensitive environments Traditionally, Human-Computer Interaction has been concerned with designing interactive systems for the workplace, which involved task- and goal-oriented activities aiming at more efficiency and maximizing utilities. Current innovative technology and interactive media however are growing in complexity. For example, it becomes possible to embed computing and sensing capabilities into a variety of environments, services and applications resulting in communication possibilities in a much broader set of contexts. Another dynamic characteristic of these emerging technologies is that they become more and more personal, they stay and go with one person a time and are consequently used in various contexts. Having a human centered perspective implies that such sensitive environments can monitor people’s behavior and can exchange information about this behavior. Moreover, it becomes an adaptive environment that meets dreams, wishes and desires of people, circumventing the need for the user to provide all information to the system consciously and manually.

In order to cope with these dynamics of real-life innovation, researchers as well as designers increasingly find themselves looking beyond conventional methods to address user needs and requirements. On the one hand we use and develop creative research tools to get customer insight; on the other hand we exploit the capabilities of ‘emerging technologies’ in the development of innovative measurement techniques and tooling.

Photo-ethnography Photo-ethnography is just an example of a research methodology that gives valuable insight in user behavior. It helps people to express themselves by using photography, providing deep insight into their lives, needs, and motivations.

Photo ethnography Observational method; "watching" rather than "asking" Participants interact with product or solutions to need Participant take video of relevant situations under study, e.g. their pet, their car, etc. Diary kept, & report behavior and attitudes to interviewer however…

Strengths and weaknesses Watching user behavior can reveal good insights about their attitudes. Participants get highly involved in study. Unforeseen relationships may be discovered Somewhat forced environment as people may modify behavior

Mobile phones with camera functionality are currently widespread available and image resolution has been increased up to 5 megapixels; these personal devices are therefore most conveniently situated for capturing (real-time) personal experiences in a less obtrusive and easy way.

Research on social cohesion… insights in sense of insecurity Respondents take their mobile phone with them Make a picture at places they feel insecure.. These pictures can be easily uploaded to the researcher’s blog Picture include automatic descriptions of the location, time, and annotated later on.

Having state of the art knowledge on methods of human centered design, students are enticed to exploit common available tools and techniques (RFID, Bluetooth, mobile phones, logging) and develop their own measurement tool and validate it in real-life context. Results from such in-situ evaluation are used to polish one’s measurement techniques and consequently contribute to the methodological innovation of the Human Centered ICT toolkit.
