An Input Interface with Speech and Touch Screen

Evaluation of User Interface Design and Input Methods for Applications on Mobile Touch Screen Devices

With the advent of touch screen phones, good UI design and simplified input methods for applications running on such devices are important factors that contribute to its popularity and success. The goal of this research is to evaluate different user interface designs and input methods for mobile phones with touch screen capability. In order to do this, two prototypes of a simple social networki...

Visual Screen: Transforming an Ordinary Screen into a Touch Screen

Touch screens are very convenient because one can directly point to where it is interesting. This paper presents an inexpensive technique to transform an ordinary screen into a touch screen using an ordinary camera. The setup is easy: position a camera so it can see the whole screen. The system calibration involves the detection of the screen region in the image. which determines the projective...

Remix_Dance 3: Improvisatory Sound Displacing on Touch Screen-Based Interface

Remix_Dance Music 3 is a quadraphonic quasi-fixed tape piece; an improviser can operate 60 pre-designed audio files using the Max/MSP-based interface. The audio files appear as icons, and the improviser can touch and drag them to four speakers in a miniature room on a tablet. Within the fixed duration of six minutes, the performer can freely activate/deactivate the audios and realize 32 differe...

Hand Posture's Effect on Touch Screen Text Input Behaviors: A Touch Area Based Study

Mobile devices with touch keyboards have become ubiquitous, but text entry on these devices remains slow and errorprone. Understanding touch patterns during text entry could be useful in designing robust error-correction algorithms for soft keyboards. In this paper, we present an analysis of text input behaviors on a soft QWERTY keyboard in three different text entry postures: index finger only...

Design and Control of an Integrated Haptic Interface for Touch Screen Applications
