The human-centred design of a product or a service begins with the needs and
wishes of its users. The user's perspective is retained throughout the design
process. With human-centred design approach the designed services and products
get more usable and they provide better user experiences. VTT provides Human
centred design services from planning and managing the human-centred
design process to individual design and evaluation activities.
At the beginning of the design process it is often impossible to know exact
user requirements. Therefore, design starts with initial user requirements,
which are re-defined as the design process moves ahead. Design ideas are
demonstrated to users and feedback is actively collected from them. Usage
scenarios, visualisations, paper prototypes and computerised prototypes can be
used to facilitate communication between designers and users.
The user's perspective must be taken into account from the start of the design
process: the earlier a new user requirement is identified or an old one
redefined, the easier it is to take these changes into account during product
According to the ISO standard (ISO 9241-210:2010, Human-Centred Design for
Interactive Systems, International Organization for Standardization),
human-centred design process consists of four kinds of activities that recur
during each iteration cycle of the design process:
understanding and specifying the context of use
specifying the user requirements
producing design solutions to meet user requirements
evaluating designs against requirements
Human-centred design underlines the importance of co-operation between users,
designers, and usability specialists.
The design process can be complemented with user studies on the context of
use, which provide information about the physical, social, and technical
environment into which the product will be launched. The results of the user
studies can, for example, indicate whether the product should be adapted
users' existing habits of use or whether new ways of action are emerging with
the use of the product.
