The Effect Of 3D Audio And Other Audio Techniques On Virtual Reality Experience

Three studies were conducted to examine the effect of audio on people's experience in a virtual world. The first study showed that people could distinguish between mono, stereo, Dolby surround and 3D audio of a wasp. The second study found significant effects for audio techniques on people's self-reported anxiety, presence, and spatial...

Auditory signal design for automatic number plate recognition system

This paper focuses on the design of an auditory signal for the Automatic Number Plate Recognition system of Dutch national police. The auditory signal is designed to alert police officers of suspicious cars in their proximity, communicating priority level and location of the suspicious car and taking into account the auditory environment of the...

Roughness vs. contrast in natural textures

We investigate the effect of contrast enhancement on the subjective roughness of visual textures. Our analysis is based on subjective experiments with seventeen images from the CUReT database in three variants: original, synthesized textures, and contrast-enhanced synthesized textures. In Experiment 1, participants were asked to adjust the...

Transitional Journey Maps: Capturing the dynamics of operational policing

Operational police work can be characterized by the continuous switching between surveillance, responding to incidents, and office activities. Transitions between these activities are initiated by radio contact, messages on a mobile data terminal, or personal observations. The “information environment” emerging from these channels may cause...

Subband analysis and synthesis of real-world textures for objective and subjective determination of roughness

In a previous study we investigated the roughness of real world textures taken from the CUReT database. We showed that people could systematically judge the subjective roughness of these textures. However, we did not determine which objective factors relate to these perceptual judgments of roughness. In the present study we take the first step...

Audio-visual interactions in product sound design

Consistent product experience requires congruity between product properties such as visual appearance and sound. Therefore, for designing appropriate product sounds by manipulating their spectral-temporal structure, product sounds should preferably not be considered in isolation but as an integral part of the main product concept. Because visual...

Roughness in sound and vision

In three experiments the perceived roughness of visual and of auditory materials was investigated. In Experiment 1, the roughness of frequency-modulated tones was determined using a paired-comparison paradigm. It was found that using this paradigm similar results in comparison to literature were found. In Experiment 2, the perceived visual...

Impact of sound on image-evoked emotions

In two experiments the effect of sound on visual information was investigated. In Experiment 1 the effect of the visual appearance of product types with an expensive deign and with an inexpensive design on the experience of the sound recordings of these products was investigated. Recordings and pictures were systematically interchanged. Thus,...
