An animated agent’s believability, often defined as “the illusion of life,” has many facets, including the agent’s appearance, movements, and user interactions. Considering that human facial expressions are often not symmetrical, evaluating how facial ...

Source code comes in different shapes and forms. Previous research has already shown code to be more predictable than natural language at the token level: source code can be natural. More recently, the structure of code --- either as graphs or trees --- ...

People form impressions of their dialogue partners, be they other people or machines, based on cues drawn from their communicative style. Recent work has suggested that the gulf between people’s expectations and the reality of CUI interaction widens ...

Software language models have achieved promising results predicting code completion usages, and several industry studies have described successful IDE integration. Recently, accuracy in autocompletion prediction improved 12.8%[2] from training on a real-...

The field of Automated Program Repair (APR) has seen significant growth in the past decade. As the field progressed, the number of templates used by APR tools has grown substantially to increase the number of patches included within the domain each tool ...

Code completion is a popular software development tool integrated into all major IDEs. Many neural language models have achieved promising results in completion suggestion prediction on synthetic benchmarks. However, a recent study When Code Completion ...

This work investigates the practices and challenges of voice user interface (VUI) designers. Existing VUI design guidelines recommend that designers strive for natural human-agent conversation. However, the literature leaves a critical gap regarding how ...

Program code needs to be understood by both machines and programmers. While the goal of executing programs requires the unambiguity of a formal language, programmers use natural language within these formal constraints to explain implemented concepts to ...

Refactoring evaluation is a challenging research topic because right and wrong of refactoring depend on various aspects of development context such as developers' skills, development cost, deadline and so on. Many techniques have been proposed to ...

Software developers often make use of the online forums such as StackOverflow (SO) to learn how to use software libraries and their APIs. However, the code snippets in such a forum often contain undeclared, ambiguous, or largely unqualified external ...

Recent technological developments have finally brought virtual reality (VR) out of the laboratory and into the hands of developers and consumers. However, a number of challenges remain. Virtual travel is one of the most common and universal tasks ...

New interaction techniques, like multi-touch, tangible interaction, and mid-air gestures often promise to be more intuitive and natural; however, there is little work on how to measure these constructs. One way is to leverage the phenomenon of tool ...

Current statistical language modeling techniques, including deep-learning based models, have proven to be quite effective for source code. We argue here that the special properties of source code can be exploited for further improvements. In this work, ...

SharedSpaces is a WebRTC design prototype that creates a virtual media space where people can mingle and interact. Although you are in different locations, you appear side by side in front of a chosen backdrop. This interactive installation addresses ...

Human-computer interaction should be natural. However, the notion of natural is questioned due to a lack of theoretical background and methods to objectively measure the naturalness of a HCI. A frequently cited aspect of natural HCIs is their ability to ...

A frustrating aspect of software development is that compiler error messages often fail to locate the actual cause of a syntax error. An errant semicolon or brace can result in many errors reported throughout the file. We seek to find the actual source ...

The aim of this research is to generate measurable evaluation criteria acceptable to chatbot users. Results of two studies are summarised. In the first, fourteen participants were asked to do a critical incident analysis of their transcriptions with an ...

This paper explores if people perceive and perform touchless gestures differently when communicating with technology vs. with humans. Qualitative reports from a lab study of 10 participants revealed that people perceive differences in the speed of ...

This study aimed to investigate how the degree of naturalness and lexical emotional content of synthesised speech affects the subjective ratings of emotional experiences and how the naturalness of the voice affects the ratings of voice quality. Twenty-...

Because the chain of events in 3D imaging is vulnerable to different context- and technology-specific variables, it is important to understand the extent to which users can accept feature-specific differences between scenes without a decrease in the (...
