Tower viewers or standalone viewers are often found in traffic areas, events of interest, or scenic outlooks. You typically see them at tourist destinations around the world. Traditional viewers allow people to look through them and see objects in the distance magnified. They are usually unmanned, so the cost of maintaining one is fairly cheap and easy once it is installed.

Since VR allows a person to look in all directions (full 360º view), it is only natural to consider attaching a headset to a mount that allows you to look in all directions without the need for a brand ambassador.

We decided to test out and design our own viewer using a Samsung Gear VR headset. We could have used any headset, but the Samsung Gear VR worked out best because the content we created was a series of 360º videos.

Feature Requirments

The viewer needed to accomplish several things –

• Standalone – meaning a user could walk up, and it would work without a brand ambassador.
• Needed a built-in power source
• Needed to be easily cleaned and maintained
• Audio for viewer
• Needed to freely move in 36oº with the ability to look up and down.
• Needed to be adjustable

The hardware was designed around the feature requirements. The most challenging was creating a power source for the Samsung Gear VR, as the hardware can hold a charge for several hours, but we would need to keep the unit fully charged for a full-day event. This was accomplished by adding a secondary battery source within the unit to keep the mobile phone powered throughout the day. The external battery was then removed and charged in the evening.

The photo of the inside of the casing shows the different components integrated into the head unit.

The audio was played through a small speaker device embedded within the casing. Speaker systems were built out from each side of the viewing area. Volume control was integrated so the user could adjust the sound.

We also created a special application to run the experience. Similar to what we created for our retail VR viewer, we created an App that would play the 360º video and allow the user to select from several other 360º videos. The Application was smart enough to go to sleep when not in use. It also would wake up once a person moved the viewer and start the experience from the beginning in case the last user abandoned it before it was finished.

The unit was shipped in a travel container for easy transportation.
