Distance based modelling and manipulation methods for augmented reality systems using ultrasonic gloves

摘要

User input gloves and input methods are described that are well suited to provide input to computer modeling (eg CAD) and augmented reality (AR) systems, including wearable AR and spatial AR. Each glove comprises palm mounted ultrasonic transducers, accelerometers, finger based pinch inputs and a wireless communication module. The gloves can be used to measure distances over the natural range of distances that hands can be placed, as well as their orientation, with sufficient resolution to facilitate a range of gesture based input methods to be developed and utilized, including distance-based modeling by measurement. Further the gloves are light weight, allow fast input of modeling measurements, are easy to use, and reduce fatigue compared to existing glove based input systems. The user input gloves, and associated input techniques can be used to measure small and body sized objects using one or two hands, and large objects can be measured using single handed measurements. Further models for both small and large objects can be generated and manipulated through the use of a numeric input technique to obtain an amplification factor to magnify the effective distances measured.

1. A method for providing input in an augmented reality (AR) system comprising at least one user input glove comprising a distance ranging sensor, an orientation sensor, and an input event generator, and a display apparatus, the method comprising:
generating a virtual model of an object using at least one orientation of the user input glove determined from one or more orientation sensor measurements and at least one distance of an object from the user input glove measured using the distance ranging sensor; and displaying a representation of the virtual model, wherein the input event generator comprises a thumb pad portion and a contact portion at the base of the adjacent index finger, and measurement of either an orientation from the orientation sensor or a distance from the distance ranging sensor is performed in response to the user generating an input event by contacting the thumb pad portion to the contact portion.
