Cardiac auscultation allows diagnosing the heart by listening to its sounds. Current cardiac auscultation training is seeing a preference towards diagnostics equipment such as the echocardiograph that allows visualizing and listening to the heart to determine how the heart is working, rather than the use of the stethoscope which only provides auditory feedback, resulting in a loss of stethoscope-based...
In this paper, we describe and describe the quality indicators for the development of an adaptive user interface for 3D mnemonic schemes in the DSS. These indicators are of particular relevance for man-machine systems in critical applications: rocket and space technology, nuclear and thermal power engineering, transport systems and many others.
Block-based languages are a useful scaffold for novice programmers to create syntactically correct code. However, block environments that attempt to represent feature-rich languages, such as Python or Java, face serious usability and pedagogical challenges. How can the affordances and controls of a block be exposed, without over-complicating the block's interface and obscuring its meaning to the user?...
Tangible User Interfaces (TUI) have garnered significant interest in the past years as a potential solution to embed smarter technologies for education. The intrinsic ability of this technology to engage and intrigue students in active learning pedagogies has recently been successfully proven across all ages using various techniques. Predominantly amongst the effective technologies, has been the development...
Many Internet of Things applications provide methods to create mashup services with if-then-else approaches due to its simplicity. When a number of mashup services are increased, it may be suffered by service conflict, that is, mashup services may perform opposite actions or abnormal behavior at the same time. To overcome this issue, this paper proposes the concept of context descriptor to detect...
Software visualizations are used to support stakeholders in software engineering activities like development, project management, and maintenance. The respective tasks determine which aspects of software, i.e., structural, behavioral and/or evolutionary information, need to be visualized. To promote the usage of software visualizations they have to optimally support the needs of the respective stakeholder...
Software visualizations provide many different complex views with different filters and metrics. But often users have a specific question to which they want to have an answer or they need to find the best visualization by themselves and are not aware of other metrics and possibilities of the visualization tool. We propose an interaction with software visualizations based on a conversational interface...
This paper investigates the relationship between audio models for Virtual Reality (VR) video with respect to the senses of immersion and realism that each model delivers. Mono, Stereo, 5.1 Surround Sound, and a Virtual Spatialised Position configuration was developed for testing in a VR music video and evaluated with a user study. Participants experienced the VR video with these differing audio models...
In the era of the development of mobile technology, direct communication becomes a rare thing between humans to their families, causing the spatial communication between families, be it close family, distant family, or extended family. This can lead to familial relationships disappear, so that the grandchildren do not know their family tree properly. The “Geni.com” app provides a feature to record...
Being equipped with an appropriate user interface, building operating systems are capable of providing transparent information on energy consumption and generation in the household and achieving interaction with residents to implement energy management and optimization. In order to help provide a reference for the design of a more comprehensive user interface for building operating systems in the...
The purpose of this research is to infer the effect of web elements on web visual design. First, semantic differential Technique is applied to inquire the influence of web elements on website banner and content section and then we advance AE analysis of visual components properties of cognitive. At last, the statistical analysis is used to suggest web design reference. The paper presents a user interface...
Despite the increasing use of internet by Iranians, the bounce rates of the e-commerce websites are still high. This is because the e-commerce institutions are not familiar with designing websites based on their own target market preferences. So the purpose of this paper is to identify and to evaluate the effective visual factors for attracting online users. This study has been conducted by an attitude...
Voice-based systems allow users access to information on the internet over a voice interface. Prior studies on Open and Distance Learning (ODL) e-examination systems that make use of voice interface do not sufficiently exhibit intelligent form of assessment, which diminishes the rigour of examination. The objective of this paper is to improve on the achievements of previous studies by providing a...
We explore design approaches for cooperative work in virtual manipulation tasks. We seek to understand the fundamental aspects of the human cooperation and design interfaces and manipulation actions to enhance the group's ability to solve complex manipulation tasks in various immersion scenarios.
In this paper, a summary of various sensory technologies and interactions within them in wearable platforms is presented. In the first part of the paper, we discuss the way humans perceive various sensory inputs. Then, we review today's state of art sensor technologies for user interfaces, followed by discussions on opportunities uniquely enabled by the wearable form factor.
With the evolution of mobile technology, many devices are introduced with very limited screen sizes like smart glasses. This technology must be accompanied with new visualization techniques. A classic interface can't meet the expectations of the user who becomes increasingly hard to please. The challenge is to display information and allow the user a better navigation with less effort especially in...
Suppose we are given an autonomous vehicle that has limitations, meaning that it may need to transfer control back to the human driver to guarantee safety in certain situations. This paper presents work on designing a user interface to assist this hand off by considering the effects of the expression of internal and external awareness. Internal awareness is the concept of knowing whether or not the...
Accurately identifying images with subtly varying features from a large set of similar images can be a challenging task. To succeed, viewers must perceive subtle differences between multiple nearly identical images and react appropriately. The Rapid Serial Visual Presentation (RSVP) display technique has the potential to improve performance as it exploits our ability to preattentively recognize differences...
The Symbolic Execution Debugger (SED) is an extension of the Eclipse debug platform for interactive symbolic execution. Like a traditional debugger, the SED can be used to locate the origin of a defect and to increase program understanding. However, as it is based on symbolic execution, all execution paths are explored simultaneously. We demonstrate an extension of the SED called Interactive Verification...
Even today "beeps" are mostly used in consumer electronics (CE) as user interface (UI) sounds. Though this has not changed for at least 10 years, we think UI sounds could be designed more useful and fascinated. This time we investigated what kinds of sound are used on recent CE UIs, and how users use and what they think of these sounds. As a result, users mostly understand the message when...
