From Smart Light Dimmers to the IPOD: Text-Input with Circular Gestures on Wheel-Controlled Devices
نویسندگان
چکیده
A uni-stroke text input strategy for wheel input controls is proposed, such as the wheel controls found on the 5th generation ipod multimedia devices. The popularity of the ipod indicates that the wheel input paradigm is intuitive and usable. The proposed uni-strokes are based on circular motions that follow the contour of the wheel. Spatial mnemonics based on the shape of the alphabetic characters are used to minimize the time and effort learning the uni-strokes. An approximate distance based method is used for robust character recognition of uni-stroke patterns.

DiMaß: A Technique for Audio Scrubbing and Skimming using Direct Manipulation
Scrubbing or skimming through an audio-only recording remains a challenge with today’s audio interfaces. We present DiMaß, a technique for direct manipulation of an audio timeline with continuous, high-fidelity audio feedback. Building upon prior work in interactive conducting systems, DiMaß uses improved algorithms to (1) estimate the input position and velocity of low sampling rate, relative ...
متن کاملNeural Network Performance Analysis for Real Time Hand Gesture Tracking Based on Hu Moment and Hybrid Features
This paper presents a comparison study between the multilayer perceptron (MLP) and radial basis function (RBF) neural networks with supervised learning and back propagation algorithm to track hand gestures. Both networks have two output classes which are hand and face. Skin is detected by a regional based algorithm in the image, and then networks are applied on video sequences frame by frame in...
متن کاملInvestigating the Characteristics of Unistroke Gestures using a Mobile Game
Touch gestures are today’s main input method for the interaction with smart phones. In particular, unistroke gestures, which are gestures consisting of one articulated line, are commonly used for text input (touch keyboards) and short cuts referring to functions on mobile devices. This work investigates the user’s accuracy of articulating unistroke touch gestures on mobile devices. Therefore, t...
متن کاملGenerating Similarity-based Playlists Using Traveling Salesman Algorithms
When using a mobile music player en-route, usually only little attention can be paid to its handling. Nonetheless it is desirable that all music stored in the device can be accessed quickly, and that tracks played in a sequence should match up. In this paper, we present an approach to satisfy these constraints: a playlist containing all tracks stored in the music player is generated such that i...
