Today touchscreens are one of the most common input devices for everyday ubiquitous interaction. Yet, capacitive touchscreens are limited in expressiveness; thus, a large body of work has focused on extending the input capabilities of touchscreens. One ...

As computers become common in different work environments, more accessible forms of interaction are required so that blind people may cost-effectively perform computer-based tasks requiring precise input. The human hand has 14 digital bones called ...

Modern tablets support simultaneous pen and touch input, but it remains unclear how to best leverage this capability for bimanual input when the nonpreferred hand holds the tablet. We explore Thumb + Pen interactions that support simultaneous pen and ...

Touch interaction has reached high popularity due to the widespread use of handheld devices. Nowadays, devices with screen sizes above 8 are not uncommon. Grasping such big handheld devices needs two hands to feel comfortable. Consequently, only the two ...

We present BackPat - a technique for supporting one-handed smartphone operation by using pats of the index finger, middle finger or thumb on the back or side of the device. We devise a novel method using the device's microphone and gyroscope that ...

We present BackPat: A technique for supporting one-handed smartphone operation. Using pats of either the index finger or middle finger or thumb on the back or side of the device, the user can extend one-handed use in a variety of difficult tasks. We ...

We present a predictive model for the functional area of the thumb on a touchscreen surface: the area of the interface reachable by the thumb of the hand that is holding the device. We derive a quadratic formula by analyzing the kinematics of the ...

Mobile touch devices have become increasingly popular, yet typing on virtual keyboards whilst walking is still an overwhelming task. In this paper we analyze; firstly, the negative effect of walking on text-input performance, particularly the users' ...

Dual width instruction set embedded processors such as ARM provide 16-bit instruction set in addition to the 32-bit instructions set for lower energy and memory cost. The combination of hardware multithreading technique with the 16-bit code design can ...

For many embedded applications, program code size is a critical design factor. One promising approach for reducing code size is to employ a “dual instruction set”, where processor architectures support a normal (usually 32-bit) Instruction Set, and a ...

An experimental apparatus was developed to measure force production of a digit at various points of force application along the digit and in any direction within the transverse plane of the longitudinal axis of the digit. Eight normal subjects with ...

Code size is a critical concern in many embedded system applications, especially those using RISC cores. One promising approach for reducing code size is to employ a "dual instruction set", where processor architectures support a normal (usually 32 bit) ...

The range of human kinematic motion as well as force resolution should be known for design of a haptic device. In addition, a haptic interface can be designed more easily when master and slave devices are the same kinematically. However, human kinematic ...
