[publication] Distance Learning and Assistance Using Smart Glasses #tugraz #smartglass #AugmentedReality

Our newest research on “Distance Learning and Assistance Using Smart Glasses” got published within a special issue, called “Challenges and Future Trends of Distance Learning“.


With the everyday growth of technology, new possibilities arise to support activities of everyday life. In education and training, more and more digital learning materials are emerging, but there is still room for improvement. This research study describes the implementation of a smart glasses app and infrastructure to support distance learning with WebRTC. The instructor is connected to the learner by a video streaming session and gets the live video stream from the learner’s smart glasses from the learner’s point of view. Additionally, the instructor can draw on the video to add context-aware information. The drawings are immediately sent to the learner to support him to solve a task. The prototype has been qualitatively evaluated by a test user who performed a fine-motor-skills task and a maintenance task under assistance of the remote instructor.

[publication] OmniColor – A Smart Glasses App to Support Colorblind People #iJIM #tugraz

Georg investigated in his masterthesis the usefulness of Google Glass for colorblind people. We published his results in our article about “OmniColor – A Smart Glasses App to Support Colorblind People“.


Colorblind people or people with a color vision deficiency have to face many challenges in their daily activities. Their disadvantage to perceive colors incorrectly leads to frustration when determining the freshness of fruits and the rawness of meat as well as the problem to distinguish clothes with confusing colors. With the rise of the smartphone, numerous mobile applications are developed to overcome those problems, improving the quality of live. However, smartphones also have some limitations in certain use cases. Especially activities where both hands are needed do not suit well for smartphone applications. Furthermore, there exist tasks in which a continuous use of a smartphone is not possible or even not legally allowed such as driving a car. In recent years, fairly new devices called smart glasses become increasingly popular, which offer great potential for several use cases. One of the most famous representatives of smart glasses is Google Glass, a head-mounted display that is worn like normal eyeglasses produced by Google. This paper introduces an experimental prototype of a Google Glass application for colorblind people or people with a color vision deficiency, called OmniColor and meets the challenge if Google Glass is able to improve the color perception of those people. To show the benefits of OmniColor, an Ishihara color plate test is performed by a group of 14 participants either with, or without the use of OmniColor.
