Krista M. Wilkinson; Savanna Brittlebank; Allison Barwise; Tara O'Neill Zimmerman; Janice Light – Augmentative and Alternative Communication, 2024
Eye tracking research technologies are often used to study how individuals attend visually to different types of AAC displays (e.g. visual scene displays, grid displays). The assumption is that efficiency of visual search may relate to efficiency of motor selection necessary for communication via aided AAC; however, this assumption has not…

The Effects of Color Cues on Typically Developing Preschoolers' Speed of Locating a Target Line Drawing: Implications for Augmentative and Alternative Communication Display Design
Peer reviewed Peer reviewed
Direct linkDirect link
Thistle, Jennifer J.; Wilkinson, Krista – American Journal of Speech-Language Pathology, 2009
Purpose: This research examined how the presence of color in relation to a target within an augmentative and alternative communication array influenced the speed with which typically developing preschoolers located a target line drawing. Method: Fifteen children over the age of 4 years (from 4;2 [years;months] to 5;4) and 15 children under the age…

Content-Based Image Retrieval Using a Composite Color-Shape Approach.
Peer reviewed Peer reviewed
Mehtre, Babu M.; Kankanhalli, Mohan S.; Lee, Wing Foon – Information Processing & Management, 1998
Proposes a composite feature measure which combines the shape and color features of an image based on a clustering technique. A similarity measure computes the degree of match between a given pair of images; this technique can be used for content-based image retrieval of images using shape and/or color. Tests the technique on two image databases;…

Prototypes and Idealizations in Natural Language Shape Descriptions.
Heidorn, P. Bryan – Proceedings of the ASIS Annual Meeting, 1998
Describes a graphic modeling, natural language processing system, VerbalImage, which mimics features of human shape reasoning. Subjects read the same text description and were able to recognize the image generated by the computer from among a series of other computer-generated images. Performance on task was as good as for a control group…

Automatic Caption Localization for Photographs on World Wide Web Pages.
Peer reviewed Peer reviewed
Rowe, Neil C.; Frew, Brian – Information Processing & Management, 1998
Explores the indirect method of locating for indexing the likely explicit and implicit captions of photographs, using multimodal clues including the specific words used, syntax, surrounding layout of the Web page, and general appearance of the associated image. The MARIE-3 system thus avoids full image processing and full natural-language…

Design and Evaluation of a User Interface Supporting Multiple Image Query Models.
Mostafa, Javed; Dillon, Andrew – Proceedings of the ASIS Annual Meeting, 1996
Describes the ViewFinder interface, designed at Indiana University as a client to a database server; it supports querying based on both visual and verbal clues. Presents results of usability analysis performed on ViewFinder with 18 users. High search success rates were achieved through both types of querying means; verbal clues were used more than…
