HCI Ambient and peripheral displays

It is common in the ubicomp literature to see the term “ambient display” used
interchangeably with “peripheral display”, but in this question, we are going to want you
to consider them as separate, but related, ideas on how to present information to an
individual. The answers to parts a-c can be given in a paragraph, and the answer to
parts d-should be more extensive and relate to existing literature on the topic.

A. One of the first examples of an ambient display was noted by Weiser through the
work by artist Natalie Jeremijenko, called the Dangling String or LiveWire. Briefly
explain how that display worked.

B. Based on the operation of Dangling String, define an ambient display in terms of the
relationship between the information in the physical world that is to be communicated
and the means by which that information is portrayed to someone viewing the ambient
display.

C. Weiser wrote about the notion of “calm” computing, describing a world in which
information did not constantly scream for attention, but could be made easily available
when and if an individual desired. The idea of a peripheral display comes from this idea
of an individual being able to easily move some piece of information from the
background to the foreground of their attention. Given this definition of a peripheral
display, what is the relationship between an ambient display and a peripheral display?
Give an example of an ambient display that may or may not be a peripheral display.
Give an example of a peripheral display that may or may not be an ambient display.

D. Mankoff et al. (CHI 2003) showed how to adapt an existing HCI evaluation technique,
heuristic evaluation, to support the specific design challenges of ambient displays. Pick
some existing usability evaluation technique and discuss how it could be applied to
evaluate peripheral displays. Describe how aspects of the usability technique may or
may not need to be adapted to target the relevant features of a peripheral display (e.g.,
its “calmness”).

E. Briefly outline how you would conduct a research study to determine whether your
modified usability technique works, in the same way that Mankoff et al. conducted a
research study to demonstrate how heuristic evaluation adapted for ambient displays
worked.

  3. Insight Generation: Visualization promotes insight generation by enabling analysts to explore and interact with data in real-time. Interactive visualization tools allow users to manipulate parameters, filter data, and drill down into specific subsets, enabling them to uncover hidden insights and make data-driven decisions more effectively. For instance, interactive dashboards can visualize key performance indicators (KPIs) and allow users to explore data from different perspectives, leading to actionable insights and improved decision-making.
  4. Communication and Collaboration: Visualization enhances communication and collaboration by providing a common visual language for conveying complex information to diverse audiences. Visualizations serve as powerful communication tools that can convey insights, findings, and recommendations more effectively than textual or numerical data alone. By presenting data visually, analysts can communicate their findings to stakeholders, decision-makers, and the broader public in a compelling and accessible manner.
  5. Predictive Analytics: Visualization supports predictive analytics by enabling analysts to visualize historical data, model outcomes, and evaluate predictive models. Visualizations of predictive models, such as decision trees, regression analysis, or neural networks, help analysts understand model behavior, identify influential features, and interpret model predictions. This understanding is critical for validating model performance, identifying areas for improvement, and making informed decisions based on predictive insights.
