Exploring Button Design for Low Contrast User Interfaces

Abstract

Mainstream display technologies have progressed towards higher resolutions and contrast levels. However, for IoT applications, where displays are embedded in the environment, there are requirements to optimize displays for lower power consumption or minimal environmental impact, potentially sacrificing contrast or switching time. We approach this issue by considering the spatial design of UI components. As a first step, we explore switch type UI components (e.g., check box, toggle switch) and evaluate the performance of 4 alternative spatial designs at low contrast levels. As a contribution, we open the issue of spatial UI design for low contrast and demonstrate an approach for its evaluation.

Service Design Methods for the Design of Smart Surfaces

“…EC materials are not light emitting, making them suitable for environments such as the bedroom, where artificial light may have negative impact on human sleep patterns (Czeisler, 2013). Finally, EC displays are very thin (around 3 mm), flexible and can be produced in in any shape (Jensen, Colley, Häkkilä, et al, 2019), which enables their integration into a variety of different products as user interfaces (Colley, Genç, et al, 2021) or soft robots (Löchtefeld & Milthers, 2021), and are specifically suited for interactive smart surfaces.…”

Prototyping and Design of Transparent and Flexible Electrochromic Displays

“…EC displays have already been used in a variety of different applications, from simple user interfaces [1], notifications [20], hybrid board games [12], over ambient lighting [10,11], wearables [3,6,8], as part of a learning activity [19] or in a soft robot [18]. We hope that this course will motivate participants to develop novel applications for EC displays as well as to investigate the field of printed electronics for HCI further.…”

ECPlotter: A Toolkit for Rapid Prototyping of Electrochromic Displays

“…In addition to being non-light emitting, electrochromic displays hold their display content even when removed from an energy source, resulting in a low power consumption [4]. While the first electrochromic displays were limited to a single-color only, recently researchers have also shown how to fabricate multilayered color displays (Naijoh et al.…”

“…TransPrint [16,31,32] extends this line of work by presenting a fabrication process for screen-printing electrochromic displays, which uses an off-the-shelf hardware setup that can be used in makerspace activities [18] by non-experts to produce their own display designs. Based on this technique also a variety of prototypical applications have been developed in the past, ranging from simple user interfaces [4], notifications [36], hybrid board games [21], over ambient lighting [19,20], wearables [5,15,17], as part of a learning activity [30] or in a soft robot [34]. For our research, we built onto this work and will try to automate the fabrication process of electrochromic displays using printed electronics.…”
