This work develops a theoretical framework for a virtual community for people with long-term, severe mobility disabilities. It proposes strategies for implementing a virtual community model based on user information needs. The central theme to emerge from their narratives is how the use of information and communications technology (ICT) allows them to regain a sense of control. The conclusion is that the technology provides strategies for independence and facilitates self-empowerment.
The purpose of virtual reality is to make possible a sensorimotor and cognitive activity for a user in a digitally created artificial world. Recent advances in computer technology have led to a new generation of VR devices such as VR headsets. Accordingly, virtual reality poses many new scientific challenges for researchers and professionals. The aim of this book, a manual meant for both designers and users of virtual reality, is to present the current state of knowledge on the use of VR headsets in the most complete way possible. The book is divided into 13 chapters. The objective of the first chapter is to give an introduction to VR and clarify its scope. The next chapter presents a theoretical approach to virtual reality through our Immersion and Interaction methodology also known as "3I^2 model". Then, a chapter about human senses is necessary to understand the sensorimotor immersion, especially vision. These chapters are followed by several chapters which present the different visual interfaces and the VR headsets currently available on the market. These devices can impart comfort and health problems due to sensorimotor discrepancies. A chapter is devoted to these problems, followed by a chapter that gives a detailed discussion of methods and 32 solutions to dispel, or at least to decrease, VR sickness. The following three chapters present different VR applications that use VR headsets (behavioural sciences, industrial uses and Digital Art) and the final chapter provides conclusions and discusses future VR challenges.
What's a mother to do, besides dishes and dinners and dirty laundry? Being a mom is one of the very best "jobs" a woman can have, but sometimes it would be nice to slip away for a conference with other moms, right? Grateful mom, and now grandmother, Margery Kisby Warder invites readers to a "virtual" retreat that fits any mom's schedule and nearly every budget. Margery believes we need never outgrow our imaginative gifts, so she's prepared a "women's event" that an attendee holds in her hands. Of course a few friends could gather while little ones are preoccupied and discuss what the virtual guest speakers told about their lives as mothers. Who wouldn't want to hear from Eve? From Mrs. Noah? How about listening to wealthy Sarah and the lessons she's learned after giving birth to Isaac when she's ninety? These celebrity women of the Bible will the the presenters - but if you put the book down, you can come back to the very last word she spoke. Why, that may even be almost as good as getting together with other gals for a ladies' time away. The price of the ticket to this event is whatever you paid for the book. The worth? That depends upon how much you gather from the speakers, the author's comments, and the scriptures that are printed within the book for your easy access to them. Come on, get comfortable, the festival for women is about to begin and no one is going to take that spot reserved for you.
