Natural language interface using constrained intermediate dictionary of results

Abstract: A method for processing a natural language input provided by a user includes: providing a natural language query input to the user; performing, based on the input, a search of one or more language-based databases; providing, through a user interface, a result of the search to the user; identifying, for the one or more language-based databases, a finite number of database objects; and determining a plurality of combinations of the finite number of database objects. The one or more language-based databases include at least one metadata database including at least one of a group of information types including case information, keywords, information models, and database values.

Ecological Interfaces for Improving Mobile Robot Teleoperation

Abstract: Navigation is an essential element of many remote robot operations including search and rescue, reconnaissance, and space exploration. Previous reports on using remote mobile robots suggest that navigation is difficult due to poor situation awareness. It has been recommended by experts in human-robot interaction that interfaces between humans and robots provide more spatial information and better situational context in order to improve an operator's situation awareness. This paper presents an ecological interface paradigm that combines video, map, and robot-pose information into a 3-D mixed-reality display. The ecological paradigm is validated in planar worlds by comparing it against the standard interface paradigm in a series of simulated and real-world user studies. Based on the experiment results, observations in the literature, and working hypotheses, we present a series of principles for presenting information to an operator of a remote robot.

SpeechSkimmer: a system for interactively skimming recorded speech

Abstract: Listening to a speech recording is much more difficult than visually scanning a document because of the transient and temporal nature of audio. Audio recordings capture the richness of speech, yet it is difficult to directly browse the stored information. This article describes techniques for structuring, filtering, and presenting recorded speech, allowing a user to navigate and interactively find information in the audio domain. This article describes the SpeechSkimmer system for interactively skimming speech recordings. SpeechSkimmer uses speech-processing techniques to allow a user to hear recorded sounds quickly, and at several levels of detail. User interaction, through a manual input device, provides continuous real-time control of the speed and detail level of the audio presentation. SpeechSkimmer reduces the time needed to listen by incorporating time-compressed speech, pause shortening, automatic emphasis detection, and nonspeech audio feedback. This article also presents a multilevel structural approach to auditory skimming and user interface techniques for interacting with recorded speech. An observational usability test of SpeechSkimmer is discussed, as well as a redesign and reimplementation of the user interface based on the results of this usability test.

Handheld dimensioner with data-quality indication

Abstract: A handheld dimensioner with a user interface configured to present a quality indicator is disclosed. The handheld dimensioner is configured to capture three-dimensional (3D) data and assess the three-dimensional-data's quality. Based on this quality, a quality indicator may be generated and presented to a user via the user interface. This process may be repeated while the user repositions the handheld dimensioner. In this way, the user may use the quality indicators generated at different positions to find an optimal position for a particular dimension measurement.

Dynamic resizing of clickable areas of touch screen applications

Abstract: A method for increasing ease-of-use of a touch screen application by dynamically resizing touch screen input areas is disclosed. The touch screen application includes a user interface that displays one or more touch screen input areas. Each of the touch screen input areas include a viewable area and a clickable area, wherein a user's touch of the clickable area activates the corresponding touch screen input area. Aspects of the present invention include collecting coordinates of touches on the display in response to user interaction, and analyzing the touch coordinates to determine how often the user has missed the input areas. In response to the number of missed touches reaching a predetermined threshold, both the size of the viewable area and the clickable area of at least one of the input areas, and possibly all areas of a similar size or type, are increased so that the input areas will be easier to touch.
