Air-Text provides various functionalities by the seamless integration of Air-Writing and Text-Recognition Modules. Specifically, the Air-Writing Module takes a sequence of RGB images as input and tracks both the location of fingertips and current hand gesture class frame by frame.
9 Νοε 2015 · We investigate the relative effectiveness of various feature dimensions of optical and inertial tracking signals and report the attainable recognition performance correspondingly. The proposed system achieves a word error rate of 0.8% for word-based recognition and 1.9% for letter-based recognition. We also subjectively and objectively evaluate ...
17 Οκτ 2021 · The proposed Air-Text is an integrated real-time text entry system. Air-Text is composed of air-writing and text-recognition module and works on a stream of RGB images. Air-writing module localizes fingertips and classifies gestures for tracking and system control.
17 Οκτ 2021 · Existing radar-based solutions often perform the mid-air writing recognition by tracking the hand trajectory using multiple monostatic or bistatic radars. This article presents ...
1 Ιουν 2019 · In this paper, using the Kinect depth and color images, an air-writing system is proposed to identify single characters such as digits or letters and connected characters such as numbers or words. In this system, automatic clustering, slope variations detection, and a novel analytical classification are proposed as new approaches to eliminate ...
In this paper, we have introduced a method to implement air writing which allows users to trace lin- guistic characters in a pen-up pen-down motion of finger or hand thereby eradicating the need to write continuously. The proposed method is not frus- trated by the requirement of extra hardware like a data glove or a specialized camera.
19 Νοε 2022 · Detecting intended writing among extraneous finger/object movements entirely irrelevant to letters or words poses a challenge which should be addressed in the common pattern recognition methods. We propose a system that writes the exact mean of the motion that is drawn in front of the sensor using Hidden Markov Algorithm and OpenCV.
