  • Patent number: 10600336
    Abstract: A real-time multimodal image perception system to transform the standard lab blood smear image for persons with BVI to perceive, employing a combination of auditory, haptic, and vibrotactile feedbacks. These sensory feedbacks are used to convey visual information in appropriate perceptual channels, thus creating a palette of multimodal, sensorial information. A Bayesian network is provided to characterize images through two groups of features of interest: primary and peripheral features. A method is provided for optimal matching between primary features and sensory modalities.
    Type: Grant
    Filed: October 3, 2016
    Date of Patent: March 24, 2020
    Assignee: Purdue Research Foundation

  • Publication number: 20160353055
    Abstract: A method and system for remote collaboration and remote instruction utilizing computing devices at trainee site and mentor sites are disclosed. Annotations are superimposed onto a trainee's view of a view field displayed using a simulated transparent display with augmented reality (“AR”). By tracking the position of the trainee's view point, the position of the trainee's computing device, and the geometry of the view field, the annotations remain anchored to the image of the view field when the trainee device moves and/or when the view field deforms or becomes occluded.

  • Publication number: 20160116985
    Abstract: A system and method to project gesture patterns of gestural behavior designed for existing gesture systems to those exhibited by persons with limited upper limb mobility, such as quadriplegics due to spinal cord injury (SCI), hemiplegics due to stroke, and persons with other types of disabilities. The system acquires a plurality of gesture instances from a gesture sensor, maps the plurality of gesture instances, determines a union amongst the plurality of gesture instances to thereby acquire a plurality of trajectory points, encodes the plurality of trajectory points into a feature vector, extracts a plurality of features from the feature vector, normalizes the plurality of features, determines at least one transform function from the plurality of features, and generates constrained gestures from the at least one transform function to form at least one gesture set.
