PURPOSE To determine the effect of reducing spatial uncertainty by attentional cueing on contrast sensitivity at a range of spatial locations and with different stimulus sizes. METHODS Six observers underwent perimetric testing with the Humphrey Visual Field Analyzer (HFA) full threshold paradigm, and the output thresholds were compared to conditions where stimulus location was verbally cued ...

This paper reports experiments on speech production showing that secondary stress in Brazilian Portuguese (BP) can be best described as phrase-initial prominence cued by greater duration and pitch accent excursion in initial position. It also reports a perception experiment in which clicks were associated to consecutive V-to-V positions in stress groups. Mean click detection RTs are gradient, b...

Purpose Current clinical perimetric test paradigms present stimuli randomly to various locations across the visual field (VF), inherently introducing spatial uncertainty, which reduces contrast sensitivity. In the present study, we determined the extent to which spatial uncertainty affects contrast sensitivity in glaucoma patients by minimizing spatial uncertainty through attentional cueing. ...

Objectives: This paper studies the effect of Persian Cued Speech on the perception of Persian language phonemes and monosyllabic words with and without sound in hearing impaired children. Cued Speech is a sound based mode of communication for hearing impaired people that is comprised of a limited series of hand complements and the normal pattern of speech. And it is shown that it effectively ca...

Cued Speech is a communication system that complements lip-reading with a small set of possible handshapes placed in different positions near the face. Developing a Cued Speech capable system is a time-consuming and difficult challenge. This paper focuses on how an existing bank of reference Cued Speech gestures, exhibiting natural dynamics for hand articulation and movements, could be reused f...

background and aim: cued speech makes speech perception easier and improves both lip-reading ability and residual hearing usage. the purpose of the present study was to assess the effectiveness of using cued speech on story retelling as a rehabilitation tool for late cochlear implanted, prelingual, hearing-impaired students. methods: this was an experimental study with a pre- and post-test plan...

An important usability goal for knowledge based authentication systems is to support users in selecting passwords of higher security. We use persuasion to influence user choice in click based graphical passwords, encouraging users to select more random and hence more difficult to guess, click points. Passwords theft can happen on daily basis, so we need to protect them. A distributed system pro...
