Implementing RSVP as an Image Browser
نویسنده
چکیده
Rapid Serial Visual Presentation (RSVP) is an effective tool for information navigation. We applied RSVP to the increasingly important task of image browsing. In total nine RSVP interfaces were developed, implementing three RSVP modes and three control sets. An evaluation was carried out to investigate the effect of RSVP mode and control set on image retrieval time. Subjective measures were also taken using the NASA Task Load Index (TLX) worksheets. In the evaluation, a traditional thumbnailed image browser was used, so as to give a base for comparison. Choice of RSVP mode was found to have the greatest effect on image retrieval speed and user preference, with interfaces implementing floating RSVP performing significantly better than those implementing other RSVP modes. The floating RSVP interfaces were faster than the thumbnailed approach but not significantly so. Subjective satisfaction favoured the floating RSVP interfaces over the thumbnailed interface.

Remote Client and One-Pass Signalling
We present and evaluate two experimental extensions to RSVP in terms of protocol specification and implementation. These extensions are targeted at apparent shortcomings of RSVP to carry out lightweight signalling for end systems. Instead of specifying new protocols, our approach in principle aims at developing an integrated protocol suite, initially in the framework set by RSVP. This work is b...
متن کاملMultirapid Serial Visual Presentation Framework for EEG-Based Target Detection
Target image detection based on a rapid serial visual presentation (RSVP) paradigm is a typical brain-computer interface system with various applications, such as image retrieval. In an RSVP paradigm, a P300 component is detected to determine target images. This strategy requires high-precision single-trial P300 detection methods. However, the performance of single-trial detection methods is re...

PURPOSE To develop and evaluate an improved method of generating en face fundus images from three-dimensional optical coherence tomography images which enhances the visualization of drusen. METHODS We describe a novel approach, the restricted summed-voxel projection (RSVP), to generate en face projection images of the retinal surface combined with an image processing method to enhance drusen ...
متن کاملGeneralizing RSVP's traffic and policy control interface
In this paper, we describe our current efforts to evaluate and extend the traffic control interface of RSVP and to define a useful policy control interface. The particular goal is to advance integration of non-broadcast multiple-access (NBMA) sub-nets, such as native ATM, and furthermore, to allow for meaningful inter-operation between traffic control and policy control. Our experience stems fr...
متن کاملAutomatic computation of an image’s statistical surprise predicts performance of human observers on a natural image detection task
To understand the neural mechanisms underlying humans' exquisite ability at processing briefly flashed visual scenes, we present a computer model that predicts human performance in a Rapid Serial Visual Presentation (RSVP) task. The model processes streams of natural scene images presented at a rate of 20Hz to human observers, and attempts to predict when subjects will correctly detect if one o...
