  • Design, implementation and case study of a pragmatic vibrotactile belt

    IEEE Transactions on Instrumentation and Measurement

    Recently, much research in the area of haptic technologies has focused on the development of waist-worn vibrotactile belts as substitution or augmentation modalities for audio-visual information. Vibrotactile belts have been used in varied applications, such as navigational aids, spatial orientation display, and balance control. Researchers have mostly focused on the functionality of these vibrotactile belts for specific applications while neglecting performance and usability. Considering the…

    Recently, much research in the area of haptic technologies has focused on the development of waist-worn vibrotactile belts as substitution or augmentation modalities for audio-visual information. Vibrotactile belts have been used in varied applications, such as navigational aids, spatial orientation display, and balance control. Researchers have mostly focused on the functionality of these vibrotactile belts for specific applications while neglecting performance and usability. Considering the versatility of a vibrotactile belt, we previously conducted a study on the design requirements for vibrotactile belts and introduced an implementation based on these design guidelines. This paper builds on our previous work and provides details for the implementation of a ubiquitous wearable vibrotactile belt. A case study is presented in which the proposed belt was used by a researcher for a novel application of teaching participants choreographed dance. The usability of the belt is demonstrated from the researcher's perspective in terms of functionality and performance and from the participants' perspectives in terms of usability attributes such as comfort and unobtrusiveness.

  • A Pragmatic approach to the design and implementation of a vibrotactile belt and its applications

    International Workshop on Haptic Audio visual Environments and Games (HAVE)

    A human centered pragmatic approach to the design and implementation of a vibrotactile belt is presented in this paper. Based on (a) extensive usability feedback we've collected over the past year, and (b) a thorough survey of existing design guidelines from the literature, we propose a set of design guidelines for the development of haptic belts that can span seamlessly across various applications. These guidelines cover three important aspects for haptic belts: functionality, performance and…

    A human centered pragmatic approach to the design and implementation of a vibrotactile belt is presented in this paper. Based on (a) extensive usability feedback we've collected over the past year, and (b) a thorough survey of existing design guidelines from the literature, we propose a set of design guidelines for the development of haptic belts that can span seamlessly across various applications. These guidelines cover three important aspects for haptic belts: functionality, performance and usability, which are vital for longitudinal use by end users. Taking a human-centric approach from these design guidelines, we demonstrate the construction of a wirelessly controlled haptic belt design that is versatile, usable and practical. Implementation details of the belt are given, along with a preliminary usability study and a brief review of some of the important application areas of haptic belts. Results from the usability study reveal that participants were very pleased with the proposed haptic belt, and found it to be easy to wear and use.

  • Reconfigurable Processing

    Issued US 8,281,297

    A method of producing a reconfigurable circuit device for running a computer program of moderate complexity such as multimedia processing. Code for the application is compiled into Control Flow Graphs representing distinct parts of the application to be run. From those Control Flow Graphs are extracted basic blocks. The basic blocks are converted to Data Flow Graphs by a compiler utility. From two or more Data Flow Graphs, a largest common subgraph is determined. The largest common subgraph is…

    A method of producing a reconfigurable circuit device for running a computer program of moderate complexity such as multimedia processing. Code for the application is compiled into Control Flow Graphs representing distinct parts of the application to be run. From those Control Flow Graphs are extracted basic blocks. The basic blocks are converted to Data Flow Graphs by a compiler utility. From two or more Data Flow Graphs, a largest common subgraph is determined. The largest common subgraph is ASAP scheduled and substituted back into the Data Flow Graphs which also have been scheduled. The separate Data Flow Graphs containing the scheduled largest common subgraph are converted to data paths that are then combined to form code for operating the application. The largest common subgraph is effected in hardware that is shared among the parts of the application from which the Data Flow Graphs were developed. Scheduling of the overall code is effected for sequencing, providing fastest run times and the code is implemented in hardware by partitioning and placement of processing elements on a chip and design of the connective fabric for the design elements.
