Show, Prefer And Tell: Incorporating User Preferences Into Image Captioning, Annika Lindh, Robert J. Ross, John Kelleher
Show, Prefer And Tell: Incorporating User Preferences Into Image Captioning, Annika Lindh, Robert J. Ross, John Kelleher
Conference papers
Image Captioning (IC) is the task of generating natural language descriptions for images. Models encode the image using a convolutional neural network (CNN) and generate the caption via a recurrent model or a multi-modal transformer. Success is measured by the similarity between generated captions and human-written “ground-truth” captions, using the CIDEr [14], SPICE [1] and METEOR [2] metrics. While incremental gains have been made on these metrics, there is a lack of focus on end-user opinions on the amount of content in captions. Studies with blind and low-vision participants have found that lack of detail is a problem [6, 13, …
Multi-Sensor Localization And Tracking In Disaster Management And Indoor Wayfinding For Visually Impaired Users, Zhuorui Yang
Multi-Sensor Localization And Tracking In Disaster Management And Indoor Wayfinding For Visually Impaired Users, Zhuorui Yang
Doctoral Dissertations
This dissertation proposes a series of multi-sensor localization and tracking algorithms particularly developed for two important application domains, which are disaster management and indoor wayfinding for blind and visually impaired (BVI) users. For disaster management, we developed two different localization algorithms, one each for Radio Frequency Identification (RFID) and Bluetooth Low Energy (BLE) technology, which enable the disaster management system to track patients in real-time. Both algorithms work in the absence of any pre-deployed infrastructure along with smartphones and wearable devices. Regarding indoor wayfinding for BVI users, we have explored several types of indoor positioning techniques including BLE-based, inertial, visual …
The Mpt Assessment Deployed Via Digital Mobile Application, Niall Duffy
The Mpt Assessment Deployed Via Digital Mobile Application, Niall Duffy
Dissertations
This project will look at the area of the Matching Person and Technology assessment (MPT). This project will be to develop a version of the MPT that can be deployed as a mobile application. The key research being performed in this project will be the analysis of the results given on the mobile application when compared to those given via the traditional paper method. The MPT is a very large assessment; because of this there are a number of different specific assessments like workplace and education assessments (Cook, A.M. and Hussey, S. 2001). Because of the size of the assessment …
Low Cost Neurochairs, Frankie Pike
Low Cost Neurochairs, Frankie Pike
Master's Theses
Electroencephalography (EEG) was formerly confined to clinical and research settings with the necessary hardware costing thousands of dollars. In the last five years a number of companies have produced simple electroencephalograms, priced below $300 and available direct to consumers. These have stirred the imaginations of enthusiasts and brought the prospects of "thought-controlled" devices ever closer to reality. While these new devices were largely targeted at video games and toys, active research on enabling people suffering from debilitating diseases to control wheelchairs was being pursued. A number of neurochairs have come to fruition offering a truly hands-free mobility solution, but whether …
Biometric Alternatives To Captcha: Exploring Accessible Interface Options, Anita Foley
Biometric Alternatives To Captcha: Exploring Accessible Interface Options, Anita Foley
Dissertations
In the computing domain the relationship between accessibility and security is a complex and evolving one; accessibility attempts to ensure that as wide a range of individuals as possible are granted access to systems, whereas security attempts to restrict access only to individuals who are entitled to access those systems. A key security concern is to determine whether or not the system is being accessed by a software agent or a real human being, and a number of approaches have been developed to determine the answer to this question. This issue has been discussed throughout the history of computer science …
Can A Self Assessement Tool For Environmental Controls Which Has Been Informed By Users Be Of Benefit To Potential Users, Sean Loughran
Can A Self Assessement Tool For Environmental Controls Which Has Been Informed By Users Be Of Benefit To Potential Users, Sean Loughran
Dissertations
This dissertation looks at the area of environmental control systems (ECS) also known as electronic aids for daily living for people with disabilities. These systems allow an individual with a disability to control devices such as a television, music player, telephone as well as a door, window or curtain controllers. A self-assessment tool was developed for potential users, which was informed by the feedback of (i) users who use or who have used environmental control systems, (ii) Enable Ireland staff who were involved in the service delivery of ECS and (iii) companies who install ECS for individuals with disabilities. These …
On Improving Electrooculogram-Based Computer Mouse Systems: The Accelerometer Trigger, Johnalan Keegan, Edward Burke, James Condron, Eugene Coyle
On Improving Electrooculogram-Based Computer Mouse Systems: The Accelerometer Trigger, Johnalan Keegan, Edward Burke, James Condron, Eugene Coyle
Conference Papers
Eye tracking is a well-established method of computer control for profoundly paralysed people (Anson et al., 2002). Cameras are commonly used to track eye movements (Morimoto et al., 2005) but one alternative is the bioelectrical signal known as the electrooculogram (EOG). There are some EOG mouse control systems that facilitate the use of GUI applications, but certain actions, which are straightforward using a conventional mouse, remain impossible. Unless the eyes are tracking a target, they move in saccades (jumps), making it impossible to voluntarily trace out smooth trajectories with one's gaze, as would be required to draw a smooth curve. …
