In this paper we review the limitations of existing theories in explaining cybersickness and propose a practical alternative approach. We start by providing a clear operational definition of provocative motion stimulation during active HMD VR. In this situation, whenever the user makes a head movement, his/her virtual head will tend to trail its true position and orientation due to the display lag (or motion to photon latency). Importantly, these differences in virtual and physical head pose (DVP) will vary over time. -

Motion and Context Sensing Techniques for Pen Computing
Motion and Context Sensing Techniques for Pen Computing Ken Hinckley1, Xiang ‘Anthony’ Chen1,2, and Hrvoje Benko1 * Microsoft Research, Redmond, WA, USA1 and Carnegie Mellon University Dept. of Computer Science2 ABSTRACT We explore techniques for a slender and untethered stylus prototype enhanced with a full suite of inertial sensors (three-axis accelerometer, gyroscope, and magnetometer). We present a taxonomy of enhanced stylus input techniques and consider a number of novel possibilities that combine motion sensors with pen stroke and touchscreen inputs on a pen + touch slate. These Fig. 1 Our wireless prototype has accelerometer, gyro, and inertial sensors enable motion-gesture inputs, as well sensing the magnetometer sensors in a ~19 cm Χ 11.5 mm diameter stylus. context of how the user is holding or using the stylus, even when Our system employs a custom pen augmented with inertial the pen is not in contact with the tablet screen.

Organizing Screens with Mission Control | 61
Organizing Screens with 7 Mission Control If you’re like a lot of Mac users, you like to do a lot of things at once. No matter how big your screen may be, it can still feel crowded as you open and arrange multiple windows on the desktop. The solution to the problem? Mission Control. The idea behind Mission Control is to show what you’re running all at once. It allows you to quickly swap programs. In addition, Mission Control lets you create multiple virtual desktops (called Spaces) that you can display one at a time. By storing one or more program windows in a single space, you can keep open windows organized without cluttering up a single screen. When you want to view another window, just switch to a different virtual desktop. Project goal: Learn to use Mission Control to create and manage virtual desktops (Spaces). My New Mac, Lion Edition © 2011 by Wallace Wang lion_book-4c.indb 59 9/9/2011 12:04:57 PM What You’ll Be Using To learn how to switch through multiple virtual desktops (Spaces) on your Macintosh using Mission Control, you’ll use the following: > Mission Control > The Safari web browser > The Finder program Starting Mission Control Initially, your Macintosh displays a single desktop, which is what you see when you start up your Macintosh. When you want to create additional virtual desktops, or Spaces, you’ll need to start Mission Control. There are three ways to start Mission Control: > Start Mission Control from the Applications folder or Dock. > Press F9. -
19Th Century Writing Activity: Pen &
Lesson Plan: #NoyesArtatHome 19th Century Writing Activity: Pen & Ink Activity based on letters on display in the Noyes Museum’s Estell Empire Exhibition For ages 12 & up Experience with cursive* writing not necessary Assistance from an adult would be helpful. Overview: Round Hand Script: This was the dominant cursive* writing style among 19th century writing “masters,” whose An account book from John Estell’s general store models were engraved on metal. Letters Circa 1836 – 1837 sloped to the right, and thick lines were © Collection of Stockton University produced on the downstrokes using a flexible, straight-edged (not pointed) pen nib (tip). Thin lines were made by using the corner of the nib. Round hand included decorative swirls referred to as “command of hand.” Copperplate: This type of writing was made with a flexible, pointed metal pen. Copperplate script differs from round hand in the gradual swelling of the broad strokes on curved forms and the narrowness of the backstrokes of b, e, and o. Definitions from Britannica.com: https://www.britannica.com/topic/black-letter Project Description: This lesson provides a brief overview of handwriting in the 19th century and a hands-on writing activity. First, paint with a teabag to make “old” looking paper. To write, use a quill** pen with black ink or watered-down paint, or a marker. Try to read and copy the example of 19th century writing. Can you write your own name, or a whole letter to a friend? Supplies: 8.5 x 11” piece of paper A tea bag; preferably a darker tea such as black tea (Lipton, Red Rose) A watercolor brush Your choice of: a quill** pen and black ink, watered-down black paint with a fine-tipped brush, or a black marker (for example: Crayola – “broad line” or Sharpie – “fine point,” the newer, the better) *Cursive writing is a style of writing in which all of the letters in a word are connected. -
