Canny, Chair With an estimated 4.6 billion units in use, mobile phones have already become the most popular computing device in human history. Their portability and communication capabil- ities may revolutionize how people do their daily work and interact with other people in ways PCs have done during the past 30 years. Despite decades of experiences in creating modern WIMP (windows, icons, mouse, pointer) interfaces, our knowledge in building ef- fective mobile interfaces is still limited, especially for emerging interaction modalities that are only available on mobile devices. This dissertation explores how emerging sensors on a mobile phone, such as the built-in camera, the microphone, the touch sensor and the GPS module can be leveraged to make everyday interactions easier and more efficient.

    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.

  • KSPC (Keystrokes Per Character) As a Characteristic of Text Entry Techniques
    KSPC (Keystrokes per Character) as a Characteristic of Text Entry Techniques I. Scott MacKenzie Dept. of Computer Science York University Toronto, Ontario, Canada M3J 1P3 +1 416 736 2100 WQEGOIR^MI$EGQSVK Abstract. KSPC is the number of keystrokes, on average, to generate each character of text in a given language using a given text entry technique. We systematically describe the calculation of KSPC and provide examples across a variety of text entry techniques. Values for English range from about 10 for methods using only cursor keys and a SELECT key to about 0.5 for word prediction techniques. It is demonstrated that KSPC is useful for a priori analyses, thereby supporting the characterisation and comparison of text entry methods before labour-intensive implementations and evaluations. 1 Introduction An important research area in mobile computing is the development of efficient means of text entry. Interest is fueled by trends such as text messaging on mobile phones, two-way paging, and mobile web and email access. Coincident with this is the continued call in HCI for methods and models to make systems design tractable at the design and analysis stage [5]. This paper addresses these two themes. We propose a measure to characterise text entry techniques. It is calculated a priori, using a language model and a keystroke-level description of the technique. The measure is used to characterise and compare methods at the design stage, thus facilitating analyses prior to labour-intensive implementations and evaluations. 2 Keystrokes per Character (KSPC) KSPC is an acronym for keystrokes per character. It is the number of keystrokes required, on average, to generate a character of text for a given text entry technique in a given language.

  • Off-The-Shelf Stylus: Using XR Devices for Handwriting and Sketching on Physically Aligned Virtual Surfaces

  • Displaying Images on the SMART Sympodium
    Displaying Images on the SMART Sympodium Anything you can display on your computer monitor will be projected onto the SMART Sympodium when you are connected to the system. For example, you could display: Word Documents Images Pages on the Internet PowerPoint Presentations Statistical or Design Programs Touching the SMART Sympodium screen with the pen stylus is equivalent to clicking on your computer screen using your mouse. Tap once on the Sympodium for a single mouse click; tap twice on the Sympodium for a double click. Drawing on the Sympodium Screen Use the stylus attached to the SMART Sympodium to draw on the screen. Do not write on the SMART Sympodium screen with dry-erase markers or pens. Note that the stylus pen color is changeable. It will write in the color you select by pen color selection buttons located at the top of the Sympodium screen. Also note that the pen and mouse are interchangeable. However if you lay the pen on the screen,the mouse will not function properly. Always rest the pen near the inside bottom of the screen when not in use. Note the buttons at the bottom of the Sympodium panel. These are shortcuts to some of the Sympodium tools. By default, the Floating Tools are not active. To activate them, click on the Start Menu and then "SMART Board Tools". The toolbar will fade in on the left side of the screen. To customize the appearance of your tools: Click on the "Gear" icon at the bottom of the Floating Toolbar. Drag the desired tool onto the bar; likewise, drag the undesired tool away.

    Stylus Enhancement to Enrich Interaction with Computers Yu Suzuki, Kazuo Misue, and Jiro Tanaka Department of Computer Science, University of Tsukuba 1-1-1 Tennodai, Tsukuba, Ibaraki 305-8573, Japan {suzuki,misue,jiro}@iplab.cs.tsukuba.ac.jp Abstract. We introduce a technique to enrich user interaction with a computer through a stylus. This technique allows a stylus to be manipulated in the air to operate applications in new ways. To translate the stylus manipulation into application behavior, we take an approach that we attach an accelerometer to the stylus. Such a stylus allows control through new operations like rolling and shaking, as well as through conventional operations like tapping or making strokes. An application can use these operations to switch modes or change parameters. We have implemented a number of applications, called the “Oh! Stylus Series,” that can be used with our proposed technique. Keywords: Stylus Enhancement, Interaction, Accelerometer, Behavior. 1 Introduction Computer operations based on a stylus, compared to those with a mouse, have the advantage of being direct and easy to understand. In terms of the interaction style, though, most stylus operations simply replace mouse operations, so these operations do not take advantage of all the ways a pen-shaped device can be handled. Potential interface techniques have not been realized because computers cannot detect stylus positions and movements when a conventional stylus is not touching the display. Our goal is to make pen-based applications more useful by enabling a computer to detect such manipulations of a stylus and use them to govern applications run on the computer.

  • Neonatal Intubation Simulation with Virtual Reality and Haptic Feedback
    Neonatal Intubation Simulation with Virtual Reality and Haptic Feedback BME 400 University of Wisconsin Madison Department of Biomedical Engineering October 10th, 2018 Team Members: Team Leader: Carter Griest ​ Communicator: Isaac Hale ​ BSAC: Sara Martin ​ BPAG: Jessi Kelley ​ BWIG: Joey Campagna ​ Advisor: Beth Meyerand (Medical Imaging) ​ Clients: Dr. Ryan McAdams and Dr. Brandon Tomlin ​ Abstract Respiratory distress syndrome (RDS), a neonatal disease characterized by difficulty breathing, is remarkably common among premature infants, affecting up to 60% of the population. Patient outcomes resulting from RDS are undesirably poor. Neonatal intubation, the primary treatment for RDS, is an extremely difficult procedure to perform. Unsatisfactory patient outcomes are in part due to ineffective training methods, which include video instruction and intubation performed on mannequins. A more realistic training method that better replicates the procedure’s technical challenges and stressful nature would enhance physician competency, resulting in improved clinical outcomes. Virtual reality (VR) is an innovative tool becoming increasingly used in the medical field, particularly for simulations. VR provides a means by which individuals can be visually and acoustically immersed in a non-physical, yet responsive, environment. Via the incorporation of haptic feedback devices, virtual simulations can include somatosensory feedback, greatly increasing simulation realism. Cutting edge medical VR simulations with haptic feedback already exist and represent the future of medical training. Integration of a well-designed virtual environment with haptic devices that imitate a neonatal intubation procedure would provide a more effective means of training. Currently, the simulation includes a prototype operating room, and beginnings of a 3D replication of a neonate and upper respiratory anatomy.
