Exploring Thumb Input on Flexible Tablets
… explore the potential of touch input using the thumb of the holding hand on flexible displays. We conducted two studies to evaluate tapping and swiping with thumb input, and compared the interactions between a flexible and a rigid tablet. Our result suggests that participants can perform tapping …

Design and control of a robotic thumb using piezoelectric actuators
… and used to develop a one degree of freedom thumb using a hybrid DC motor/PZT actuator system. To study system performance, a simple position control scheme was implemented for the DC motor and PZT actuators. The experimental results suggest that current PZT actuators, even when combined with …

Clarinet Thumb-rest Function: The Pedagogy of Positioning and Electromyography Evidence
… the weight of their instrument on their right thumb using a small metal attachment called a thumb-rest. The soprano clarinet weighs only two pounds, but many hours of playing can cause general discomfort to severe overuse injury throughout the upper right limb. There is a debate within the …

A device for quantitative assessment of thumb Ulnar Collateral Ligament injury
… to the Ulnar Collateral Ligament (UCL) of the thumb, known as "Skier's Thumb," is treated by surgical repair for complete tears, or by splinting for partial tears. Because of this radical difference in treatment options, diagnostic accuracy is critical. The primary mechanism of diagnosis is …

Essays on optimal monetary policy under rule-of-thumb behaviour by price setters
… effects of inflation persistence due to rule-of-thumb behaviour by price setters on optimal monetary policy. We start with a canonical log-linearised New Keynesian model, which we extend by allowing a fraction of price setters to follow a rule-of-thumb when setting a new price. We consider …

Multi-object and multi-feature models of thumb anatomy for population based morphological assessment
The trapeziometacarpal (TMC) joint, formed by the junction of the trapezium and first metacarpal (MC1) bones, is highly susceptible to the onset and progression of osteoarthritis (OA). Although various treatment options exist to ease symptoms and slow the progression of OA, the success of these …

Non-invasive detection of the electromyographic activity of the deep extrinsic thumb muscles using surface electrodes
… to detect EMG activity of the deep extrinsic thumb muscles Flexor Pollicis Longus (FPL), Extensor Pollicis Longus (EPL), Extensor Pollicis Brevis (EPB) and Abductor Pollicis Longus (APL) using surface electrodes. Methods: High density monopolar EMG was detected from 2 concentric rings, each …

Little Bodies, Little People: Conflating the Child and the Dwarf in The History of Sir Thomas Thumb
… novel, <em>The History of Sir Thomas Thumb</em>, in order to examine the ways the novel borrows from similar fairy tales and related contemporary phenomena, such as the public exhibition of dwarfs. These “people in miniature” have been examined, cooed over, ridiculed, and all too often …

Correlation of the Epiphyseal Closure and Ossification of the Ulnar Sesamoid Bone of the Metacarpophalangeal Joint of the Thumb
… sesamoid of the metacarpophalangeal joint of the thumb.</p> <p>The time for these events was studied in twenty-three males and fourteen females for which appropriate hand radiographs were available. Radiographs were made every three months and epiphyseal closure was studied in these beginning with …

A Clearer Picture of Musculoskeletal Disorders of the Knee and Thumb Through the Lens of Image-Based Finite Element Analysis
… could be used for MRI-based FEA of the basilar thumb joint. A modular MRI-compatible micropipette simulator addresses several limitations of pipetting studies, and it can be used to isolate micropipette design features to understand how they affect basilar thumb joint contact mechanics. A …

Design of a Wearable Two-Dimensional Joystick as a Muscle-Machine Interface Using Mechanomyographic Signals
… muscle-machine interface for interpreting human thumb motion as a 2-dimensional joystick employing mechanomyographic signals. Infrared camera based systems such as Microsoft Digits and ultrasound sensor based systems such as Chirp Microsystems' Chirp gesture recognizers are elegant solutions, but …

De Novo Initiated RNA Synthesis by the Hepatitis C Virus RNA-dependent RNA Polymerase
… NS5B has the characteristic fingers, thumb and palm domains seen in all polymerase proteins. However, extensive interactions between the fingers and thumb domains completely encircle the active site of NS5B as seen in solved X-ray diffraction crystal structures. These interactions are …

Behavior analysis of catching using 3D pose estimation
… quantified: 1) Euclidean distance between the thumb tip and other fingertips (opposable distance); 2) Perpendicular distance from each fingertip to the palm plane (prehensile distance); and 3) The hand's rotation angle in the X-Z plane, derived from the palm's normal vector. Results revealed …

The role of inanimate transitional objects in helping children cope with daily hassles
… as having more hassles than children using their thumb (X̅=18.88), and children using soft objects (X̅=l.34) were rated as coping less effectively than children using their thumb (X̅=.75). Among those children with inanimate transitional objects, significant positive relationships were found …
