In the context of the Scientific Information Retrieval, this experiment aims to observe dependences between user characteristics (the profile) and pertinent document characteristics (metadata). We know and use the relation between the topic of the information need and the topic of the document, but we think other less intuitive dependences exist. We built possible assumption of dependences betw...

We present a method to measure some aspects of cognitive effort by a user while reading during a search session. We measured reading eye movement properties and patterns of eye movement in a user study (n=32) of participants carrying out realistic journalism IR work tasks. The results show the cognitive effort measures correlate positively with the information task characteristics that, by hypo...

Introducing haptics into human-robot interaction brings new challenges to control algorithm development as the robot stays in physical contact with the human user. When the aim is to design a system which interacts with the human in a natural and plausible way similar to two humans carrying out the same task, the main challenges are to estimate human intentions online and to plan the behavior o...

The degradation of mobility is an important concern that affects the independent living ability physically Challenged people. Therefore, assistive devices require improvements to uplift standards This paper sets out a design smart wheelchair using embedded system. and development proposed can be controlled through bluetooth which enables user control with less effort. Touch commands are deploye...
