Mixed Reality (MR) simulation, in which a Virtual Reality (VR) system is used to simulate both the real and virtual components of an Augmented Reality (AR) system, has been proposed as a method for evaluating AR systems with greater levels of experimental control. However, factors such as the latency of the MR simulator may impact the validity of experimental results obtained with MR simulation. We present a study evaluating the effects of simulator latency on the equivalence of results from an MR simulator and a real AR system. We designed an AR experiment which required the participants to visually follow a virtual pipe around a small room filled with real targets and to find and identify the targets which were intersected by the pipe. We show that, with a 95% confidence interval, the results from all three simulated AR conditions fall well within one standard deviation of the real AR case.

We seek to close the gap between software engineering (SE) and human-computer interaction (HCI) by indicating interdisciplinary interfaces throughout the different phases of SE and HCI lifecycles. As agile representatives of SE, Extreme Programming (XP) and Agile Modeling (AM) contribute helpful principles and practices for a common engineering approach. We present a cross-discipline user interface design lifecycle that integrates SE and HCI under the umbrella of agile development. Melting IT budgets, pressure of time and the demand to build better software in less time must be supported by traveling as light as possible. We did, therefore, choose not just to mediate both disciplines. Following our surveys, a rather radical approach best fits the demands of engineering organizations. © 2007 Thomas Memmel, Fredrik Gundelsweiler, Harald Reiterer.

The microblogging service Twitter has become an important, and sometimes primary, source of information for many users. As a forum for sharing news and discussing events, it can provide instant access to the latest updates, but this is not always welcome. In the case of television shows or live sporting events, for example, tweets about them may reveal spoilers to users in different time zones or who are delaying their viewing until later. More broadly, because Twitter is a broadcast medium, users may often want to temporarily or permanently hide content about a very specific given topic. In this paper, we describe the unique challenges to HCI, social computing, and computational linguistics posed by the task of building an interface that blocks all tweets about a specific event or topic. We illustrate some of the challenges through a pilot experiment run for three major television events: the 2009 NFC Championship football game, the 2010 mid-season finale of the show Glee, and the 2010 season premiere of the show 24. While simple techniques achieve very high recall (> 98%), spoilers still make it through the filter and precision is extremely poor. We conclude with a description of challenges to the community in implementing this new and increasingly important feature. Copyright 2012 ACM.

In this paper we will describe a new approach to navigation and interaction with the visualization of a data space of an electronic product data management (EPDM) system. The main problems are the amount of data and therefore the location of an item of interest, show specific relations and narrow or expand the information space. We combine a scalab.e visualization of the hierarchical data space with search and filter techniques like dynamic queries and direct manipulation to solve the stated problems. We assume that the proposed concept for EPDM can be adapted to data spaces like social networks or company structures. Copyright 2008 ACM.

In this paper, we consider the hidden Markov model(HMM) parameter compensation in noisy environments with multiple noise sources based on the vector Taylor series(VTS) approach. General formulations for multiple environmental variables are derived and systematic expectation-maximization(EM) solutions are presented in maximum likelihood(ML) sense. It is assumed that each noise source is independent and having Gaussian distribution. To evaluate proposed method, we conduct speaker independent isolated word recognition experiments in various noisy environments. Experimental results show that proposed algorithm ahieves significant improvement. Especially, the proposed method is consistently more effective than the parallel model combination(PMC) based on log-normal approximation. © 1997 5th European Conference on Speech Communication and Technology, EUROSPEECH 1997.

An Alternate Reality Game (ARG) is a form of transmedia storytelling, with narrative elements that are distributed across multiple communications platforms, ranging from print materials to mobile devices. ARGs also represent a new genre of transmedia practice where players collab.ratively hunt for clues, make sense of disparate information, and solve puzzles to advance an ever-evolving storyline. While players participate in an ARG using everyday communications tools, such as phones and web sites, the interaction design challenges are not an "everyday" process. Designers must create and connect story bits across multiple media (video, audio, text) and multiple platforms (phones, computers, physical spaces). Further, they must engage and connect with players of varying skill levels. Few studies have explored the design process of education-based ARGs, or their relationship to participatory design. This research systematically investigates the design and play of ARGs as participatory design spaces and vehicles for scaffolding information literacy practices. © 2012 Author.

Six-degrees-of-freedom (6-DOF) trackers, which were mainly for professional computer applications, are now in demand by everyday consumer applications. With the requirements of consumer electronics in mind, we designed an optical 6-DOF tracker where a few photo-sensors can track the position and orientation of an LED cluster. The operating principle of the tracker is basically source localization by solving an inverse problem. We implemented a prototype system for a TV viewing environment, verified the feasibility of the operating principle, and evaluated the basic performance of the prototype system in terms of accuracy and speed. We also examined its application possibility to different environments, such as a tabletop computer, a tablet computer, and a mobile spatial interaction environment. © 2011 ACM.

My father's kitchen table

interactions 2008年第1期15卷 67-68页

作者： Druin, Allison University of Maryland Human-Computer Interaction Lab.

Allison Druin, director of the human-computer interaction lab.(HCIL), shared her experiences during her research work for the development of advanced interactive technologies. Druin wandered about her father's mode of interaction with a wireless mouse that he used to find much more complex than the wired input devices. Druin concluded that those people who are at the beginning of their lives or those who have experienced a great deal of life can be concerned about their physical abilities, memory recall, and how robust the technology really is. HCI professional were only required to understand users' lifelong interaction between people of their technologies, and further support the opportunities for advanced technologies and possibilities for the future.

Pulitzer Prize-winning journalist Nicholas Kristof argues that "in this century the paramount moral challenge will be the struggle for gender equality around the world." In this paper, we present a design model for empowering low-income women in the developing world, in ways that cut across individual application areas. Specifically, this model characterizes a possible trajectory for NGOs and women to engage with each other and among themselves - potentially augmented by technology - to help women escape from poverty. The fieldwork components in this study took place over 15 weeks in three phases, with a total of 47 NGO staff members and 35 socio-economically challenged women in rural and urban India. Interviews and co-design sessions with seven proof-of-concept prototypes showed that women appeared to belong to five distinct stages of "growth" in striving towards independence. We report the technology design lessons from our co-design sessions to illustrate how user readiness, relationship building at the community and family levels, and integration with state, national and international level programs, should be taken into account in the broader context of intervention design.

The lack of reliable, personalized information often complicates sexual violence survivors' support-seeking. Recently, there is an emerging approach to conversational information systems for support-seeking of sexual violence survivors, featuring personalization with wide availab.lity and anonymity. However, a single best solution might not exist as sexual violence survivors have different needs and purposes in seeking support channels. To better envision conversational support-seeking systems for sexual violence survivors, we explore personalization trade-offs in designing such information systems. We implement a high-fidelity prototype dialogue-based information system through four design workshop sessions with three professional caregivers and interviewed with four self-identified survivors using our prototype. We then identify two forms of personalization trade-offs for conversational support-seeking systems: (1) specificity and sensitivity in understanding users and (2) relevancy and inclusiveness in providing information. To handle these trade-offs, we propose a reversed approach that starts from designing information and inclusive tailoring that considers unspecified needs, respectively. © 2022 ACM.
