A novel gesture-based calculator and its design principles
نویسندگان
چکیده
A novel calculator, designed for interactive whiteboards and pen-based devices, provides a better task fit than conventional approaches. The calculator provides a natural, dynamic method of doing calculations by handwriting and using conventional notation. This paper discusses the calcualtor’s underlying design principles, which collectively create a coherent and innovative ‘look and feel.’ The principle set could be used to help improve user interfaces for other domains.

Gesture Recognition Performance Score: A New Metric to Evaluate Gesture Recognition Systems
In spite of many choices available for gesture recognition algorithms, the selection of a proper algorithm for a specific application remains a difficult task. The available algorithms have different strengths and weaknesses making the matching between algorithms and applications complex. Accurate evaluation of the performance of a gesture recognition algorithm is a cumbersome task. Performance...
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 کاملAn Accelerometer Based Calculator for Visually Impaired People Using Mobile Devices
Recent trend of touch-screen devices produces an accessibility barrier for visually impaired people. On the other hand, these devices come with sensors such as accelerometer. This calls for new approaches to human computer interface (HCI). In this study, our aim is to find an alternative approach to classify 20 different hand gestures captured by iPhone 3GS’s built-in accelerometer and make hig...
متن کاملMathematical Mathematical User Interfaces
Taking Mathematica and xThink as representatives of the state of the art in interactive mathematics, we argue conventional mathematical user interfaces leave much to be desired, because they separate the mathematics from the context of the user interface, which remains as unmathematical as ever. We put the usability of such systems into mathematical perspective, and compare the conventional app...
متن کاملGrading the Housing Design Principles based on Frequency in Evaluating Architectural Resources
One of the most important issues and human needs in the field of architectural design is "housing". From the past to the present, there have always been different principles for housing design that have been used due to the user’s needs. The set of needs and lifestyles of humans has shown that some characteristics are the same in all designed houses. These important features had been collected ...
