“…The frequent use of stepwise transitions for high priority alarms confirms the guidelines for urgent notifications of Matviienko et al [25]. Therefore, we designed four light patterns using stepwise brightness transitions.…”

“…In 2015, Matviienko et al [25] developed guidelines to map information to light patterns. They structured similarities in existing light encodings and, based on that, defined four information classes (Progress, Status, Spatial, and Notification) based on that.…”

“…However, the design space for light patterns contains more parameters than just the hue. Prior research has shown that other parameters, such as, e.g., the blinking frequency or brightness, affects the perceived urgency of the delivered information [25]. For that reason, we conducted a participatory design study to design light patterns that represent three levels of urgency, based on the given color mapping.…”

Technology plays a prominent role in intensive care units (ICU), with a variety of sensors monitoring both patients and devices. A serious problem exists, however, that can reduce the sensors’ effectiveness. When important values exceed or fall below a certain threshold or sensors lose their signal, up to 350 alarms per patient a day are issued. These frequent alarms are audible in several locations on the ICU, resulting in a massive cognitive load for ICU nurses, as they must evaluate and acknowledge each alarm. “Alarm fatigue” sets in, a desensitization and delayed response time for alarms that can have severe consequences for patients and nurses. To counteract the acoustic load on ICUs, we designed and evaluated personal multimodal alarms for a wearable alarm system (WAS). The result was a lower response time and higher ratings on suitability and feasibility, as well as a lower annoyance level, compared to acoustic alarms. We find that multimodal alarms are a promising new approach to alert ICU nurses, reduce cognitive load, and avoid alarm fatigue.

“…Ambient notifications in the form of light colors or light effects received increasing research interest distributed across recent years (e.g., [2,3,7,5,6,10]). For example, Hazlewood et al [3] studied a small spherical object made of frosted glass, which illuminated with different colors in order to reflect the confidence level of students during university courses.…”

“…Our system falls into the category symbolic sculptural display as we display only few information in an abstract sculptural way. Matviienko et al [6] studied a variety of ambient light patterns and presented design guidelines to help in designing ambient light systems. In particular, their guidelines suggest that colors known from traffic lights (which our system is based on) are most suitable for assessment of everyday situations.…”

Smart home technology became more and more widespread within recent years. They aim to make life easier and taking over unwanted tasks. In traditional homes, it is often not clear whether all windows and doors of a house are closed before inhabitants leave the home or go to sleep. However, this can be easily addressed by smart homes. We present a system based on opportunistically located ambient lights that assist inhabitants of a smart home in answering this question. In this paper, we show the concept of our system and the inhabitant-centered design process behind the development. The system was installed in a one-family smart home. We report on insights gained through data collected from this deployment over a period of six months. Within interviews, we found that the ambient light system gave inhabitants a more confident feeling about open doors/windows.

The front-seat passenger in a vehicle may assist a driver in providing hints towards points of interest in a driving situation. In order to communicate spatial information efficiently, the so-called shared gaze approach has been introduced in previous research. Thereby, the gaze of the front-seat passenger is visualized for the driver. So far, this approach has been solely investigated in driving simulator environments. In this paper, we present a study on how well shared gaze works in a real driving situation (n=8). We examine identification rates of different object types in the driving environment based on the visualization of the front-seat passenger's gaze via glowing LEDs on an LED-strip. Our results show that this rate is dependent on object relevance for the driving task and movement of the object. We found that perceived visual distraction was low and that the usefulness of shared gaze for navigational tasks was considered high.
