Claim One:
1. A method for providing augmentability feedback to a user of a user device, said user device comprising a client, a processor, a digital imaging part, a memory storage, a motion sensor and an output part, said method comprising: retrieving an image frame from the memory storage, said image frame being a digital image of a target object captured by the digital imaging part; retrieving blurring data from at least one of: the motion sensor, a camera parameter from the digital imaging part, and the image frame; determining, in the processor, image information associated with the image frame on a basis of the retrieved image frame, said image information indicative of a quality of features associated with the target object; determining blurring information associated with the user device and/or the target object on a basis of the blurring data, said blurring information indicative of the quality of the features associated with the target object; and generating augmentability feedback for the user on the basis of the image information and the blurring information, said augmentability feedback producible via the output part of the user device: wherein: said augmentability feedback represents a suitability of the image frame for use as a reference image in an object recognition and/or vision-based tracking system; the blurring data comprises at least one of: acceleration data, orientation data, data from an accelerometer, and data from a gyroscope of the user device; and determining blurring information comprises: comparing at least a part of the blurring data with at least one threshold value retrieved from the memory storage; determining a magnitude of the acceleration data and/or a magnitude of rotational rate data from the blurring data; comparing the magnitude of the acceleration data with a first threshold value for acceleration and/or the magnitude of the rotational rate data with a second threshold value for rotational rate, said first and second threshold values being retrieved from the memory storage; and if the magnitude of the acceleration data is greater than the first threshold value and/or the magnitude of the rotational rate data is greater than the second threshold value, then the method comprises setting a motion score to one of two possible values, else the method comprises setting the motion score to another of the two possible values, wherein said blurring information is based on the motion score.
