Seven segment number displays are ubiquitous and popular. They are simple and familiar. They seem to make economic sense, and with only seven segments they require little wiring and electronics to support. They are cheap to buy and cheap to use; they make seemingly effective and unproblematic products. This paper illustrates many examples of problematic uses of seven segment displays that could have been avoided. More generally, the paper raises design questions and some solutions to be… 
Rationalizing the Need of Architecture-Driven Testing of Interactive Systems
TLDR
This paper proposes to follow an opposite approach, starting from a generic architecture for interactive systems (including both software and hardware elements) for identifying in a systematic way, testing problems and testing needs and makes it possible to identify how software testing knowledge and techniques can support interactive systems testing.
Employing Number-Based Graphical Representations to Enhance the Effects of Visual Check on Entry Error Detection
TLDR
The use of number-based graphical representations (GRs) as a complement to conventional numeric representations (NR) to enhance visual checks, so users can examine both GRs and NRs to detect errors, is proposed.

TLDR
Focusing on Arabic key interfaces, which use digit keys 0-9-· usually augmented with correction keys, this paper introduces a method for formalising and managing design problems in number entry user interfaces.
The Effects of Number-related Factors on Entry Performance
TLDR
It is found that number length influenced the probability of committing errors, while the position of presentation did not, and the findings provide implications for the design of both number representations and the sociotechnical systems that surround them.
Providing Semi-private Feedback on a Shared Public Screen by Controlling Presentation Onset
We describe a novel technique to provide semi-private feedback on a shared public screen. The technique uses a no-onset presentation that takes advantage of perceptual limitations in human vision to

Interactive numerals
TLDR
Interactive numerals are introduced as a new concept and show, like Roman numerals and Arabic numerals, interactive numerals introduce another way of using and thinking about numbers.
Hidden Interfaces for Ambient Computing: Enabling Interaction in Everyday Materials through High-brightness Visuals on Low-cost Matrix Displays
TLDR
This work leverages parallel rendering to enable ultrabright graphics that can pass through everyday materials and unlock expressive hidden interfaces using rectilinear graphics on low-cost, mass-produced passive-matrix OLED displays.
StreetWise: Smart Speakers vs Human Help in Public Slum Settings
TLDR
This paper presents the findings from a detailed analysis and comparison of the two question-answer corpora; discusses how these insights might help improve machine-powered smart speakers; and, highlights the potential benefits of multi-sited public speech installations within slum environments.
Using Nomograms to Reduce Harm from Clinical Calculations
TLDR
It is argued that "the latest IT" does not automatically confer benefit: its effectiveness should be empirically evaluated like any other medical intervention, and further development and stringent evaluation are required before deployment in safety critical environments.

Interactive Numbers a Grand Challenge
Numbers are used everywhere, but today numbers are mostly created and used interactively; they are not just passive written objects. People interact with numbers in almost every area of life.
Legibility of Seven Segment Numeric LED Displays: Comparisons of Two Fonts at Various Distances
The legibility of seven segment numeric displays was investigated for two different numeric LED fonts at five reading distances. An alternative font as proposed by Van Nes and Bouma (1980) was
A Comparative Study of Seven Segment Numerics
TLDR
Where time is not critical, SN readability is comparable to CN, but in situations where time is critical, periodic SN training should be employed to preclude readability problems.
On the Legibility of Segmented Numerals
Research on the legibility of many new symbol configurations has not kept pace with their increasing use. Such novel configurations appear, for instance, in segmented numerals. This paper reports
Calculators are needlessly bad
TLDR
This article reviews a representative calculator that is “state of the art” and shows it has an execrable design, but the design is shown to be confusing and essentially non-mathematical.
FatFonts: combining the symbolic and visual aspects of numbers
TLDR
This paper introduces FatFonts, a technique for visualizing quantitative data that bridges the gap between numeric and visual representations that is based on Arabic numerals but, unlike regular numeric typefaces, the amount of ink used for each digit is proportional to its quantitative value.
Number Entry Interfaces and Their Effects on Error Detection
TLDR
An experiment that investigates the effect of interface design on error detection in number entry produces more accurate inputs than the serial interface, and the magnitude of errors suggests that the incremental interface could reduce the death rate relative to the numeric keypad.
Reducing number entry errors: solving a widespread, serious problem
TLDR
Under reasonable assumptions, it is shown that the probability of out by 10 errors can be halved by better user interface design, and a demonstration user interface is provided to show that the approach is practical.
The Art of Computer Programming
TLDR
The arrangement of this invention provides a strong vibration free hold-down mechanism while avoiding a large pressure drop to the flow of coolant fluid.
