Abstract
A wearable device is worn on the back of a user's hand such that the act of pointing the user's index finger is sufficient to align the device and trigger a process. Triggering is achieved by sensing the user's finger in an image or by breaking a light path in a photogate.
Claims20
An image-capturing device, comprising:
- an image-capturing subsystem including a multi-element image sensor for capturing images of the image-capturing subsystem's field of view;
- a hand-mounted housing substantially enclosing the image-capturing subsystem, wherein the hand-mounted housing comprises finger rings to attach to the user's middle and ring fingers so that, when a user makes a fist and fully extends the user's index finger, the user's index finger and the image-capturing subsystem are pointed substantially in the same direction;
- and
- a non-mechanical trigger mechanism configured to initiate an image-capturing sequence performed by the image-capturing subsystem if the user's index finger is detected in the images captured by the image-capturing subsystem.
1 more element
A method, comprising:
- providing an image-capturing device that comprises an image-capturing subsystem for capturing images of the image-capturing subsystem's field of view and a non-mechanical trigger mechanism for initiating an image-capturing sequence via a trigger signal;
- capturing images of the image-capturing subsystem's field of view;
- and
- generating a trigger signal if a user's finger is detected in the captured images.
1 more element
A non-mechanical triggering mechanism for a finger-mounted image-capturing device, comprising:
- a multi-element image sensor for repeatedly capturing images of a field of view;
- and
- a processor communicatively coupled to the multi-element image sensor, the processor configured by software to:
- receive a captured image from the multi-element image sensor;
- analyze the received captured image for the presence of a finger;
- and
- generate, if a finger is present in one or more captured images, a trigger signal to initiate an image-capturing sequence.
