Results of video analysis (2/3)
The following issues were identified while using the HoloLens during remote
maintenance sessions in a real-world industry setting
• Safety issues: Maintenance workers moved their heads very close to the machine.
If the machine has rotating or hot elements, this could lead to accidents and injuries.
• Ergonomic issues: In five instances, maintenance workers moved into and stayed
in awkward and uncomfortable positions to allow the expert to see the areas of
interest at the machine through the HoloLens.
• Problems in dark conditions: Videos recorded via the HoloLens may be of bad
quality under low light conditions. Furthermore, the tinted glass of the HoloLens
impairs the view of maintenance workers working under low light conditions.
• Problems in noisy surroundings: Headphones are necessary in loud
environments.

Results of video analysis (3/3)
Two issues were identified when using telephone as a communication device for
remote maintenance sessions:
• Ergonomic issues: Maintenance workers clamped the phone between head and
shoulders when they needed both hands (observed 5 times). Alternatively,
maintenance workers put the phone on a nearby table (two times) or handed it
over to colleagues (two times) to have both hands free.
• Orientation issues: Without a visual feedback-channel, spatial tasks such as
locating or finding areas of interest can be less efficient than with the HoloLens.
This effect was specifically identified in the case of the unexperienced
maintenance worker.

General findings
Areas of potential practical improvement in terms of the technology are:
• Longer battery life of the HoloLens
• Rugged hardware for daily use in production sites
• Reducing the weight of the Hololens could improve user comfort
• A remotely-controllable camera focus would enable the expert to directly focus
on areas of interest
• Additional light to illuminate the field of view of the person wearing the Hololens
• An additional camera mounted on a stick or another freely-movable and range-
extending device would be helpful to reach hard-to-access areas at machines.

Further Practical Insights and Recommendations
IT infrastructure integration
• Connection via the company network to existing data storages• Access and storage of digital information (e.g. reports, log files, status information)
• Early involvement of the IT department is highly recommended
• Consider company specific IT policies concerning OS, hardware, and data security
• IT policies may constrain the hardware and software selection
• Enabling the IT department to
• Guarantee smooth operations incl. support and maintenance of the hardware and software is crucial
AR-technology – Challenges and risks
• Hardware availability and vendor support
• Device maturity status (industrial readiness?)
• Limited number of application providers
• Missing in-house capabilities for application development
Shop-floor process related and human-centered aspects
• Application is especially beneficial for complex tasks and supporting unexperienced employees
• Occupational safety aspects
• Physiological effects

Wichtig:
- Modellierung – Eigenerstellung der virtuellen Realitaet
- Uebertragung von 3D Zeichnungen / CAT Zeichnungen
Beispiel 1:
Grosses Deutsches Logistikunternehmen
1. Wie sollen die Mitarbeiter auf das Projekt trainiert werden?
2. Wie umfangreich muss das Training sein?
3. Wie schafft es das Unternehmen, dass die Fehlerquote niedrig ist und bleibt?
4. Die Arbeitsschritte sind je nach Auto unterschiedlich.
5. Natuerlich gab es noch weitere Probleme.
Beispiel 2:
OEM
- Schwerpunkt war die Sicherheit der Mitarbeiter
Es mussten Trainingsszenarien erstellt werden – also Modelierung

Zusammengefasst:
1. Jedes Szenario kann in der virtuellen Realitaet erstellt werden2. Multi-User Szenarien sind moeglich3. User koennen in verschiedenen Laendern sitzen
