[publication] Introducing Augmented Reality at Secondary Colleges of Engineering

At this year International Conference on Engineering & Product Design Education we did a publication about the use of augmented reality in classrooms. The slides have already been published here.


In Austria there is a unique curriculum of technical education which is taught at Federal Secondary Colleges of Engineering (HTL). Despite mechanical engineering design with industrial standard 3D programmes being state of the art, techniques like Internet of Things (IoT) and Augmented Reality (AR) are still at the beginning. This paper describes the introduction of an IoT platform at Austrian HTLs with focus on Augmented Reality. In addition, a survey among students has been undertaken to get knowledge of whether students are familiar with and interested in using AR technologies and the results are presented in this paper.

[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.

[publication] Project Based Learning: from the Idea to a Finished LEGO® Technic Artifact, Assembled by Using Smart Glasses #edmedia17

The first publication at this year ED-Media conference is about „Project Based Learning: from the Idea to a Finished LEGO® Technic Artifact, Assembled by Using Smart Glasses„. The presentation has been recorded and can be find here.

Smart Glasses and 3D printers are now easily available on the market. The challenge is how to integrate them efficiently in a learning environment. This paper suggests a project-based learning (PBL) scenario how to construct, produce and assemble a planetary gear using Open Source tools, LEGO® Technic, 3D printers and Smart Glasses. The whole project-based learning scenario was implemented together with a 16-year-old student. Additionally, the assembly process using Smart Glasses was tested by seven users in a qualitative evaluation. The feedback of the student of the target group together with the feedback of other subjects was considered to improve the PBL scenario and the Smart Glasses (ReconJet) application. The evaluation showed the potential of Smart Glasses to improve hands-free assembly processes and supports the user to understand the structure and functionality of mechanical objects.

Because we are not able to attend the ED-Media conference 2017 in Washington this year, we are doing our presentations virtually. The third of four talks is about „From the Idea to a Finished LEGO® Technic Artifact, Assembled by Using Smart Glasses„:

Nun ich würde sagen, der Ansatz schaut spektakulärer aus, als er tatsächlich an Mehrwert bietet, aber immerhin ein Schritt in eine interessante Richtung:

[video] Augmented Reality and Mobile Discovery

Eine sehr schöne Augmented Reality Anwendung für das Nokia S60 ist Point & Find:

Point your mobile device’s camera at a landmark or barcode and receive immediate information such as descriptions, phone numbers and reviews, no typing required. Or join businesses like Expotel, Oasis, Joule and others already using Nokia Point & Find (Beta) to reach and interact with customers – easily, quickly and with no coding required. Mobile discovery has never been this easy.

Wenn man dies für Lernanwendungen umlegt, sehe ich vor allem die Möglichkeit dort wo man Informationen zu realen Objekten liefern kann, entweder über die Geolocation oder über einscannbare BarCodes:
