“…As stated above, sonification is intrinsically interdisciplinary. But some studies focus on either side, like the viewpoint of audio engineering [11], human factors [55,56], psychoacoustics [28,29], design [27], or arts [23,24,33]. Readers of such studies can expect to find the terminology from the respective discipline and results that are relevant to the specific discipline.…”

Sonification research is intrinsically interdisciplinary. Consequently, a proper documentation of and interdisciplinary discourse about a sonification is often hindered by terminology discrepancies between involved disciplines, i.e., the lack of a common sound terminology in sonification research. Without a common ground, a researcher from one discipline may have trouble understanding the implementation and imagining the resulting sound perception of a sonification, if the sonification is described by a researcher from another discipline. To find a common ground, the author consulted literature on interdisciplinary research and discourse, identified problems that occur in sonification, and applied the recommended solutions. As a result, the author recommends considering three aspects of sonification individually, namely 1) Sound Design Concept, 2) Objective, and 3) Evaluation, clarifying which discipline is involved in which aspect and sticking to this discipline’s terminology. As two requirements of sonifications are that they are a) reproducible and b) interpretable, the author recommends documenting and discussing every sonification design once using audio engineering terminology and once using psychoacoustic terminology. The appendixes provide comprehensive lists of sound terms from both disciplines, together with relevant literature and a clarification of often misunderstood and misused terms.

To date, sonification apps are rare. Music apps on the other hand are widely used. Smartphone users like to play with music. In this manuscript, we present Mixing Levels, a spirit level sonification based on music mixing. Tilting the smartphone adjusts the volumes of 5 musical instruments in a rock music loop. Only when perfectly leveled, all instruments in the mix are well-audible. The app is supposed to be useful and fun. Since the app appears like a music mixing console, people have fun to interact with Mixing Levels, so that learning the sonification is a playful experience. LINK TO APK FILEThe compiled Mixing Levels app can be found on my GitHub account.

“…In recent years, a number of novel HMI concepts have been proposed to both keep the driver in the loop and support drivers' re-entry into the loop after automated driving. These include tactile [11], visual [12], auditory (including speech-and non-speech-based [13]), and even olfactory cues [14]. Given drivers' likely high engagement in visual NDRTs in the future, the use of ambient Light-Emitting Displays (LEDs) has been explored as a means to provide peripheral light-based cues to drivers about an AV's current state, along with requests for a driver's attention or action.…”

Is Users’ Trust during Automated Driving Different When Using an Ambient Light HMI, Compared to an Auditory HMI?

The aim of this study was to compare the success of two different Human Machine Interfaces (HMIs) in attracting drivers’ attention when they were engaged in a Non-Driving-Related Task (NDRT) during SAE Level 3 driving. We also assessed the value of each on drivers’ perceived safety and trust. A driving simulator experiment was used to investigate drivers’ response to a non-safety-critical transition of control and five cut-in events (one hard; deceleration of 2.4 m/s2, and 4 subtle; deceleration of ~1.16 m/s2) over the course of the automated drive. The experiment used two types of HMI to trigger a takeover request (TOR): one Light-band display that flashed whenever the drivers needed to takeover control; and one auditory warning. Results showed that drivers’ levels of trust in automation were similar for both HMI conditions, in all scenarios, except during a hard cut-in event. Regarding the HMI’s capabilities to support a takeover process, the study found no differences in drivers’ takeover performance or overall gaze distribution. However, with the Light-band HMI, drivers were more likely to focus their attention to the road centre first after a takeover request. Although a high proportion of glances towards the dashboard of the vehicle was seen for both HMIs during the takeover process, the value of these ambient lighting signals for conveying automation status and takeover messages may be useful to help drivers direct their visual attention to the most suitable area after a takeover, such as the forward roadway.
