Challenging Ableism: A Critical Turn Toward Disability Justice in HCI
A reflection on our learnings from the CHI 2022 "Dreaming Disability Justice in HCI" workshop, and why we continue to call for disability justice, despite the limitations of how we practice it within academia and industry.

Brain-Load, Stress Levels, and Visual Complexity: Digital Tools for the Detection of Intangible Human-Environment Interactions
How does the built environment affect our brain? The way we perceive our environments plays a crucial role in how our brains respond to cognitive load. Understanding the impact of spatial complexities on our cognitive processes could inform future design guidelines for more responsive environments.

Remaking Everyday Objects for Physical Computing
We are surrounded by objects that have been designed and made for a wide range of purposes. Alongside the development of specialized electronic devices, we can look to these objects as a functional resource for tangible computing. By deconstructing such everyday objects and uncovering their structures, they become a material that can be remade into new physical interactive systems.

Interactive Murals: New Interactions and Educational Opportunities for Diverse Youth
Interactive murals integrate electronics into traditional murals to create a new kind of public art as well as a new kind of large-scale and community-situated technology. This article introduces interactive murals along with a set of activities designed to engage young people in technology and the arts. We describe the process and outcome of workshops in which a muralist, two interaction design researchers, and a group of diverse teenagers designed and built a large-scale interactive mural on the exterior wall of a local building.

Visualizing flow data using assorted glyphs
This project visualizes a scientific dataset containing two-dimensional flow data from a simulated supernova collapse provided by astrophysics researchers. We started our project by designing visualizations using multiple hand drawings representing the flow data without taking into consideration the implementation constraints of our designs. We implemented a few of our hand drawn designs. We used an assortment of simple geometric graphical objects, called glyphs, such as, dots, lines, arrows, and triangles to represent the flow at each sample point. We also incorporated transparency in our visualizations. We identified two important goals for our project: (1) design different types of graphical glyphs to support flexibility in their placement and in their ability to represent multidimensional data elements, and (2) build an effective visualization technique that uses glyphs to represent the two-dimensional flow field.

Explanation component of software system
Explanation is an important feature that needs to be integrated into software products. Early software that filled the horizontal software market (such as word processors) contained help systems. More specialized systems, known as expert systems, were developed to produce solutions that required specific domain knowledge of the problem being solved. The expert systems initially produced results that were consistent with the results produced by experts, but the expert systems only mimicked the rules the experts outlined. The decisions provided by expert systems include no justification, thus causing users to doubt the results reported by the system. If the user was dealing with a human expert, he could ask for a line of reasoning used to draw the conclusion. The line of reasoning provided by the human expert could then be inspected for discrepancies by another expert or verified in some other manner. Software systems need better explanations of how to use them and how they produce results. This will allow the users to take advantage of the numerous features being provided and increase their trust in the software product.

A human's eye view
Frameless Rendering (FR) is a rendering paradigm which performs stochastic temporal filtering by updating pixels in a random order, based on most recent available input data, and displaying them to the screen immediately [1]. This is a departure from frame-based approaches commonly experienced in interactive graphics. A typical interactive graphics session uses a single input state to compute an entire frame. This constrains the state to be known at the time the first pixel's value is computed. Frameless Rendering samples inputs many times during the interval which begins at the start of the first pixel's computation and ends with the last pixel's computation. Thus, Frameless Rendering performs temporal supersampling - it uses more samples over time. This results in an approximation to motion blur, both theoretically and perceptually.This paper explores this motion blur and its relationship to: camera open shutter time, current computer graphics motion-blur implementations, temporally anti-aliased images, and the Human Visual System's (HVS) motion smear quality (see 'quality' footnote) [2].Finally, we integrate existing research results to conjecture how Frameless Rendering can use knowledge of the Human Visual System's blurred retinal image to direct spatiotemporal sampling. In other words, we suggest importance sampling (see 'sampling' footnote) by prioritizing pixels for computation based on their importance to the visual system in discerning what is occurring in an interactive image sequence.

Techniques & tools for using color in computer interface design
Contemporary computers predominantly employ graphical user interfaces (GUIS) and colour is a major componenet of the GUI. Every man-machine interface is composed of two major parts:the man and the machine [4]. Color interfaces are no different in that they are also based on two parts, the Human visual system (HVS) and a color display system. A theoretical examination of these two components establishes a foundation for developing practical guidelines for color interfaces. This paper will briefly examine theoretical aspects of both components and established techniques and tools for the effective use of color for software interface design.
