This article is aimed to design new hand gesture mode of smartphone for better used by the elderly. The method first use focus grouping to find out the most difficult use hand gestures for the elderly. Secondly, we develop new gesture mode with one-finger gesture. Finally, we compare the traditional gesture with new design gesture mode. Results show that (1) use two fingers as gesture are the m...

Hand gestures are ubiquitous in communication. However, there is considerable debate regarding the fundamental role that gesture plays in communication and, subsequently, regarding the value of gesture for telecommunications. Controversy exists regarding whether gesture has a primarily communicative function (enhancing listener comprehension) or a primarily noncommunicative function (enhancing ...

Viewing hand gestures during face-to-face communication affects speech perception and comprehension. Despite the visible role played by gesture in social interactions, relatively little is known about how the brain integrates hand gestures with co-occurring speech. Here we used functional magnetic resonance imaging (fMRI) and an ecologically valid paradigm to investigate how beat gesture-a fund...

A significant body of evidence from cross-linguistic and developmental studies converges to suggest that co-speech iconic gesture mirrors language. This paper aims to identify whether gesture reflects impaired spoken language in a similar way. Twenty-nine people with aphasia (PWA) and 29 neurologically healthy control participants (NHPs) produced a narrative discourse, retelling the story of a ...

Gesture is an integral part of children's communicative repertoire. However, little is known about the neurobiology of speech and gesture integration in the developing brain. We investigated how 8- to 10-year-old children processed gesture that was essential to understanding a set of narratives. We asked whether the functional neuroanatomy of gesture-speech integration varies as a function of (...

To propose a gesture model updating and results forecasting algorithm based on Mean Shift, and to solve the problem of target model changing and influenced tracking results in gesture target tracking process. Firstly, the background difference and skin color detection methods are used to detect and get gesture model, and the Mean Shift algorithm is used to track gesture and update the gesture m...

Flick gesture systems provide an efficient alternative to common interface controls. This paper investigates the properties of natural flick gestures. These properties include gesture magnitude, gesture duration and angular error. Flick gestures are then applied to the frequent user task of web navigation. The web gesture system is then evaluated to determine the efficiency and learnability of ...

Performing action has been found to have a greater impact on learning than observing action. Here we ask whether a particular type of action - the gestures that accompany talk - affect learning in a comparable way. We gave 158 6-year-old children instruction in a mental transformation task. Half the children were asked to produce a Move gesture relevant to the task; half were asked to produce a...
