Embodiments of the invention relate to selecting a path for navigation based on a node signature and a device signature. The node signature is directly related to node attribute data. The device signature is directly related to device data. A route is selected based on a match or near match of the node and device signatures.

Automated crowd sourcing of a navigation route

Embodiments of the invention relate to selecting a path for navigation based on path accessibility. A set of one or more paths is generated, with each path including path elements associated with path traversal. A list of preference data is stored. A set of accessible paths is dynamically calculated, which includes evaluating elements of each path of the generated set against the list of preference data. The set of accessible paths is converted into a path selection. The path selection is navigated, which includes visually displaying the path selection.

Automated wayfinding of an accessible route

A method, system, and computer program product for adaptive pause detection in speech recognition are provided in the illustrative embodiments. A speech stream comprising audio signal of a speech is received. A first point in the speech stream is marked with a beginning time stamp. After the first point, a pause is detected in the speech stream. The pause is of a duration at least equal to a pause duration threshold. A second point after the pause in the speech stream is marked with an ending time stamp. A portion of the speech stream between the beginning and the ending time stamps forms a first speech segment. A speech rate of the first speech segment is computed using a number of words in the first speech segment, the beginning time stamp, and the ending time stamp. The pause duration is adjusted according to the first speech segment's speech rate.

A method, system, and computer program product for creating confidence-rated transcription and translation are provided in the illustrative embodiments. An input is provided in a first form to a set of transcription applications. A set of transcriptions is received. A first and a second set of confidence ratings are assigned to a first and a second transcription, respectively. The confidence-rated first transcription and the confidence-rated second transcription are combined and provided to a set of translation applications. A set of translations is received. A third and a fourth set of confidence ratings are assigned to a first and a second translation, respectively. The confidence-rated first and second translations are combined and presented.

Confidence-rated transcription and translation

A mechanism is provided for adapting vocabulary levels in a collaborative session. A vocabulary level indicator is received for a first user in the collaborative session. During generation of an electronic communication by a second user in the collaborative session, text entered in the electronic communication is scanned in order to identify a vocabulary level associated with text. The vocabulary level associated with the text is compared to the vocabulary level indicator for the first user. Responsive to the text exceeding the vocabulary level indicator for the first user thereby indicating violating text, an indication is provided to the second user that the violating text is above a vocabulary level of the first user.

Adaptation of vocabulary levels for enhanced collaboration

Mechanisms are provided for conference call communication in a virtual world environment. The mechanisms establish a hybrid conference call by establishing a hybrid conference call communication connection between a data based communication conference call server, that handles data based communications with client computing devices, and a telephone conference call server, that handles telephone protocol communications with telephone devices external to the virtual world environment. Communications between client computing devices and telephone devices are converted from data based communications to telephone protocol communications and vice versa using a data based communication conference call server and a telephone conference call server.

Conferencing that bridges virtual world and real-world meeting places

A method, a system, and a computer program product for providing a virtual probe, associated with an avatar, which enables blind or sightless navigation of an avatar through a virtual world. The system outputs tactile information and/or audible information that depict the presence of an object in the virtual world, in association with the avatar. When the virtual probe encounters an object in the virtual world the distance between the object and the avatar, a velocity of the object, and the dimensions of the object are determined. The tactile information, such as one or more vibrations, is output proportional to the distance between the object and the avatar and/or the dimension of the object. Audible information is also output in response to the detection of the object. Audible information, such as an audible voice, outputs one or more of the distance between the object and the avatar, the velocity of the object, and the dimensions of the object.

Three-dimensional virtual world accessible for the blind

A computer implemented method, computer program product, and a data processing system determine an excursion corridor within a virtual environment. A time-stamped snapshot of a location of at least one avatar within the virtual universe is recorded. An avatar tracking data structure is then updated. The avatar tracking data structure provides a time-based history of avatar locations within the virtual universe. A weighted density map is generated. The weighted density map is then correlated with virtual object locations. Each virtual object location corresponds to a virtual object. Excursion corridors are identified. The excursion corridor identifies frequently taken routes between the virtual object locations. Waypoints are identified. Each waypoint corresponds to a virtual object. Each waypoint is an endpoint for one of the excursion corridors.

Determining valued excursion corridors in virtual worlds

A computer implemented method, apparatus, and computer usable program code to determine whether an acknowledgment packet from an end point acknowledges receipt of unsent data in response to receiving the acknowledgement packet over a connection with the end point. A determination is made as to whether acknowledgement packets for unsent data have been received sequentially a selected number of times over the connection in response to the acknowledgement packet being for unsent data. The acknowledgment packet is dropped if acknowledgement packets have been received sequentially the selected number of times over the connection.
