This study investigated the effects of different output-based task repetition conditions on EFL learners’ speech act production. Three intact classes of English-major students constituted three instructional groups: (1) the explicit task-repetition (ETR) group, (2) the implicit task-repetition (ITR) group, and (3) the no-input task repetition (NTR) group. All the three groups engaged in t...

This paper presents a deterministic approach for performance assessment of different province’s road safety level at Iran. A data envelopment analysis (DEA) model considering undesirable input and output indices and a multivariate statistical method, principle component analysis (PCA) are used in this paper, while previous studies do not use composite PCA-DEA method and undesirable input and ou...

We developed original solenoid actuator units with several built-in sensors, and produced a box-shaped musical interface “PocoPoco” using 16 units of them as a universal input/output device. We applied up-and-down movement of the solenoid-units and user’s intuitive input to musical interface. Using transformation of the physical interface, we can apply movement of the units to new interaction d...

In this paper, we present the SensOrg, a musical Cyberinstrument designed as a modular assembly of input/output devices and musical software, mapped and arranged according to functional characteristics of the Man-Instrument system. We discuss how the cognitive ergonomics of non-verbal and symbolic task modalities influenced the design of our hardware interface for asynchronous as well as synchr...

The relative gain array (RGA) and condition number are commonly used tools in controllability analysis. In this paper we present new results that link these measures to control performance, measured in terms of the output sensitivity function with input and output uncertainty.

This is the fourth year for the minitrack on Multimedia Information Systems at the Annual Hawaii International Conference o presence of this minitrack r recent proliferation of multimedia applications. This proliferation has been driven by technological advances resulting in dramatic decreases in price/perfonnance ratios in processing and storage technologies, video and audio input/output devic...

Young children often build various structures with wooden blocks; structures that are often used for pretend play, subtly improving children’s creativity and imagination. Based on a traditional Japanese wooden block toy, Tsumiki, we propose a novel interactive toy for children, named “TSU.MI.KI”, maintaining the physical assets of wooden blocks and enhancing them with automation. “TSU.MI.KI” co...

The emergence of several trends, including the increased availability of wireless networks, miniaturization of electronics and sensing technologies, and novel input and output devices, is creating a demand for integrated, fulltime displays for use across a wide range of applications, including collaborative environments. In this paper, we present and discuss emerging visualization methods we ar...

Recent technology advances have made computer-based multimedia cooperation among distributed users feasible. Joint-Viewing (JV) is one such proposed cooperation concept. Correct interaction in it requires synchronization on various levels. In this paper we focus on synchronization aspects on the data stream level. We present several JV scenarios and state for each of these requirements concerni...
