what is human computer interaction
“HCI is a field of study, a discipline that is concerned with the design, implementation, and evaluation of interactive computer systems for human use and with the study of major phenomena surrounding them”
what is human-centered design
The approach that puts human needs, capabilities, limitations and behavior first, then designs to accommodate these.
what are the experience models
- Day-in-the-Life Model
- Identity Model
- Relationship Model
- Collaboration Model
- Sensation Board
what are the traditional contextual design models
- Sequence Model
- Decision Point Model
- Physical Model
- Personas
is driven by the realization that
a product is always part of a larger practice, used in the context of other tools and manual processes to deliver value to the user’s overall life and work
contextual design
refers to a set of models that are used to understand and analyze the context in which a system or software is used
contextual design model
what is the first phase of contextual design
- gathering of in-depth field data
- interpret as a team
illustrates the roles and responsibilities multiple people take on while they coordinate within a work process to be supported by a product.
flow model
are designed to help people internalize the world of their users
graphical models
represents the influences on a person, a group, or an organization, revealing the cultural milieu in which the product will have to succeed.
cultural model
depicts the structure and flow of activity as it manifests in space, including layout, tools used for an activity, and footsteps taken in service of the activity
physical model
represents the steps and intents of the activities to be supported, equivalent to a task analysis
sequence model
illustrates the structure and usage pattern of an artifact used during the activity, which will be put online or eliminated
artifact model
illustrates how behaviors of the target activity unfold in different places in the user’s life, detailing what is done in each location and the devices used
day-in-the-life model
highlights important relationships in the user’s life, showing how the target activity influences connections among people
relationship model
a variant of the Flow Model, captures different types of collaboration observed during interviews, including interactions and shared goals
collaboration model
reveals core identity elements relevant to the target activity, including sources of pride, self esteem, and values identified during interviews
identity model
visually represents key visceral experiences that the new product should evoke, based on data from user interviews, with key messages for designers
sensation board
are vital tools that help teams collect, incorporate, and use data related to user experiences. They provide a structured way to communicate insights derived
from users’ lives, highlighting the importance of understanding users’ behaviors and contexts
experience model’s in contextual design
is a way to involve interested
parties who are not local
- so that they can touch the detailed user experience as it is collected (another immersion opportunity)
remote participation
Capturing these models in the interpretation session makes it possible for the team to describe and analyze aspects of the user work practice in a concrete, shared, tangible way.
