abstract = {For touch typists, using a physical keyboard ensures optimal text entry task performance in immersive virtual environments. However, successful typing depends on the user’s ability to accurately position their hands on the keyboard after performing other, non-keyboard tasks. Finding the correct hand position depends on sensory feedback, including visual information. We designed and conducted a user study where we investigated the impact of visual representations of the keyboard and users’ hands on the time required to place hands on the homing bars of a keyboard after performing other tasks. We found that this keyboard homing time decreased as the fidelity of visual representations of the keyboard and hands increased, with a video pass-through condition providing the best performance. We discuss additional impacts of visual representations of a user’s hands and the keyboard on typing performance and user experience in virtual reality.},

abstract = {Immersive spaces have great potential to support analysts in complex sensemaking tasks, but the use of only manual interactions

for organizing data elements can become tedious. We analyzed

the user interactions to support cluster formation in an immersive

sensemaking system, and we designed a semi-automated cluster creation technique that determines the user’s intent to create a cluster

based on object proximity. We present the results of a user study

comparing this proximity-based technique with a manual clustering technique and a baseline immersive workspace with no explicit

clustering support. We found that semi-automated clustering was

faster and preferred, while manual clustering gave greater control to

users. These results provide support for the approach of adding intelligent semantic interactions to aid the users of immersive analytics

systems},

abstract = {Glanceable Augmented Reality interfaces have the potential to provide fast and efficient information access for the user. However, where to place the virtual content and how to access them depend on the user context. We designed a Context-Aware AR interface that can intelligently adapt for two different contexts: solo and social. We evaluated information access using Context-Aware AR compared to current mobile phones and non-adaptive Glanceable AR interfaces. We found that in a solo scenario, compared to a mobile phone, the Context-Aware AR interface was preferred, easier, and significantly faster; it improved the user experience; and it allowed the user to better focus on their primary task. In the social scenario, we discovered that the mobile phone was slower, more intrusive, and perceived as the most difficult. Meanwhile, Context-Aware AR was faster for responding to information needs triggered by the conversation; it was preferred and perceived as the easiest for resuming conversation after information access; and it improved the user’s awareness of the other person's facial expressions. },

abstract = {The recent developments in Augmented Reality (AR) eyeglasses promise the potential for more efficient and reliable information access. This reinforces the widespread belief that AR Glasses are the next generation of personal computing devices, providing efficient information access to the user all day, every day. However, to realize this vision of all-day wearable AR, the AR interface must address the challenges that constant and pervasive presence of virtual content may cause. Throughout the day, as the user's context switches, an optimal all-day interface must adapt its virtual content display and interactions. The optimal interface, that is the most efficient yet least intrusive, in one context may be the worst interface for another context. This work aims to propose a research agenda to design and validate different adaptation techniques and context-aware AR interfaces and introduce a framework for the design of such intelligent interfaces.},

abstract = {Future augmented reality (AR) glasses may provide pervasive and continuous access 

to everyday information. However, it remains unclear how to address the issue of virtual 

information overlaying and occluding real-world objects and information that are of 

interest to users. One approach is to keep virtual information sources inactive until 

they are explicitly requested, so that the real world remains visible. In this research, 

we explored the design of interaction techniques with which users can activate virtual 

information sources in AR. We studied this issue in the context of Glanceable AR, 

in which virtual information resides at the periphery of the user’s view. We proposed 

five techniques and evaluated them in both sitting and walking scenarios. Our results 

demonstrate the usability, user preference, and social acceptance of each technique, 

as well as design recommendations to achieve optimal performance. Our findings can 

inform the design of lightweight techniques to activate virtual information displays 

in future everyday AR interfaces.},
