BACKGROUND OF THE INVENTION

[003] A head-mounted display generally refers to a device worn on the head or as part of a helmet that has a display optic in front of one or each eye. Users of head-mounted displays are immersed in an array of multimedia stimuli, allowing the users to interact with the environment and engage in sensory experiences, including sight, touch, hearing, and smell. Head-mounted displays are becoming increasingly popular and accessible to the general public, allowing for a wider audience to benefit from this experience.

SUMMARY OF THE INVENTION

[004] Despite the interactive and engaging user experience provided by current head-mounted displays, they are limited in multiple aspects. First, the size and configuration of head-mounted displays may be bulky. This makes easy access, efficient storage, and reliable safekeeping of the displays challenging. Second, head-mounted displays may have supporting components separate from the display itself. This increases the chance that these components (e.g., a strap to the head- mounted display) become misplaced, lost, or stolen. These problems are further exacerbated if the user is traveling. Travelers are often limited in how much they can carry, discouraging users from bringing along their head-mounted displays and enjoying their benefits while traveling.

[005] The system and satchel disclosed herein address the problems above. The subject matter described herein includes a system which provides users a convertible satchel with integrated head-mounted display, which provides users the tools to effectively store and carry their head- mounted displays while mitigating the risk of losing components of these displays.

EXAMPLES

[032] The following illustrative examples are representative of embodiments of the software applications, systems, and methods described herein and are not meant to be limiting in any way.

Example 1— Sharing 360° Panoramic Pictures at a Picnic

[033] A 21 -year old college student is packing for a Sunday picnic with her friends. She is planning to share 360° panoramic photos of her vacation to Mexico - photos that she took on her Samsung ^® Galaxy S6 phone and that require a head mounted display to fully experience. As she is packing the bulky picnic supplies into her sports bag, she does not worry about separately making room for a head mounted display because the sports bag is already fitted with a

Samsung ^® Gear VR. She is similarly not anxious about misplacing or damaging any accessories because they are stored in a separate compartment from her picnic supplies. The student is able to conveniently carry all the picnic supplies and Samsung ^® Gear VR to the park in one sports bag. At the picnic, the student easily detaches the Samsung ^® Gear VR magnetically connected to her sports bag, takes off the sports bag strap, and converts the sports bag strap into the Samsung ^® Gear VR strap. She proceeds to insert her Samsung ^® Galaxy S6 phone into the Samsung ^® Gear VR, adjusts the strap length to fit comfortably around her head, and puts the Samsung ^® Gear VR on her head. After looking through some of her photos, she takes off the headset so she can share the immersive experience with her friends. Her friends easily adjust the strap to fit their differing head sizes. The student and her friends immerse themselves in the photos, enjoying the panoramic views of the beach, museums, and other outings. At the end of the picnic, the student easily re-attaches the Samsung ^® Gear VR back to her sports bag and conveniently carries the equipment and picnic supplies back home in one bag.

Example 2— Watching 3D Movies on a Plane

[034] A 40-year old woman is on a cross-country flight on a business trip. She is browsing the entertainment options on the flight, but none of them interest her. She is in the mood to watch a 3D movie - a feature unavailable on the flight. The business woman reaches down to her canyon luggage stowed under her seat. She unclasped the buttons attaching her head mounted display, a Carl Zeiss ^® VR One, to her luggage and inserts her Apple ^® iPhone 6, which is configured to play 3D movies, into the concavity of the Carl Zeiss ^® VR One. She then disconnects and reconfigures the carry-one luggage strap to become the strap of her Carl Zeiss ^® VR One. She is able to easily adjust the strap so it fits snugly around her head. The woman enjoys the rest of her flight watching her favorite 3D movies using her Carl Zeiss ^® VR One and Apple ^® iPhone 6. When she reaches her destination, she easily re-attaches her Carl Zeiss ^® VR One and strap back to her carry-on luggage and exits the plane carrying her head mounted display equipment and luggage in one bag. Example 3— Teaching Biology at a Student's Home with a VR Game

[035] A 31 -year old private biology tutor is teaching a junior high school student at the student's home. The lesson unit is about viruses and how they interact with the human body. The tutor first verbally explains the structures within the virus and cells, but the student does not understand. The student continues to struggle even after the tutor draws pictures of the virus and cells on a sheet of paper. The tutor reaches for his messenger bag and detaches his head mounted display, a HTC ^® Vive, which is configured to play a VR game that takes the user inside the body. He also detaches an ornamental strap from his messenger bag to become the HTC ^® Vive strap. The strap length was originally configured to fit the tutor's head, but the tutor is able to easily adjust the size to comfortably fit the student's head. The student puts on the HTC ^® Vive. The tutor turns on the VR game and the student is in an immersive VR environment, traveling through a bloodstream, going inside cells, and seeing up-close how organelles work to fight viruses. After playing the VR game, the student better appreciates how viruses work and how they interact with the human body. After the lesson is complete, the tutor easily re-attaches his HTC ^® Vive and strap back to his messenger bag and goes home.
