==Introduction==

The '''Snap Spectacles 4''' (also known as '''fourth generation Spectacles''') are [[augmented reality]] glasses developed by [[Snap Inc.]], announced on May 20, 2021, at the Snap Partner Summit. Unlike all previous generations which only featured cameras for capture, Spectacles 4 were Snap's first glasses to include actual AR displays, marking a significant milestone in the company's hardware evolution.<ref name="roadtovr">https://www.roadtovr.com/snapchat-spectacles-ar-glasses-announcement/</ref>

These glasses were not made available for consumer purchase but were instead distributed exclusively to AR creators and developers as a development kit to build AR experiences using [[Lens Studio]]. Snap planned to send out approximately 1,000 units to selected developers who applied through their creator program.<ref name="roadtovr"></ref>

==Development Philosophy==

Snap took a "form-over-function" approach with Spectacles 4, prioritizing a wearable form factor that consumers would find reasonable over raw technical capabilities. This strategy contrasted with competitors like [[Microsoft HoloLens]] and [[Magic Leap]], which traded bulkiness for greater capabilities.<ref name="roadtovr"></ref>

CEO [[Evan Spiegel]] described the glasses at launch: "Spectacles tap into our human senses of sight, touch, and sound to bring Lenses to life... Spectacles aren't for sale—they're for augmented reality creators to reimagine the way we communicate, live, and explore the world together through AR experiences built in Lens Studio."<ref name="newsroom">https://newsroom.snap.com/introducing-the-next-generation-of-spectacles</ref>

* '''Form Factor''': Traditional glasses design
* '''Battery Life''': Approximately 30 minutes of active use<ref name="roadtovr"></ref>
* '''Charging Case''': Can hold up to 4 charges<ref name="roadtovr"></ref>

==Software and Development==

===Lens Studio Integration===
Developers could create AR experiences using [[Lens Studio]], Snap's desktop application for building AR Lenses. Key features included:
* Wireless push of Lenses to Spectacles for rapid testing
* Real-time iteration capabilities
* Support for existing Lens Studio creators (250,000+ at launch)<ref name="wikipedia"></ref>

===Interaction Paradigms===
* '''Lens Carousel''': Accessed via temple touchpad
* '''Scan''': Right button activated contextual understanding to suggest relevant Lenses
* '''Voice Scan''': Hands-free Lens launching via voice commands
* '''Snap Capture''': Left button captured 10-second AR-enhanced videos<ref name="newsroom"></ref>

==Limitations and Compromises==

The push for a lightweight form factor resulted in significant technical compromises:
* '''Limited Field of View''': At 26.3 degrees, the FOV was notably narrow, requiring users to "hunt around the scene just to spot the content through the tiny window"<ref name="roadtovr"></ref>
* '''Short Battery Life''': 30 minutes made them "feel more like a dedicated-use device than something you use because you just happen to be wearing it"<ref name="roadtovr"></ref>
* '''Display Limitations''': Lower resolution compared to competitors
* '''Developer-Only''': Not available for consumer purchase<ref name="variety"></ref>

==Launch Partners and Experiences==

By December 2021, AR experiences available on the glasses included:
* A zombie chase game
* Pong game
* Solar System projection
* Interactive art pieces
* Connected Lenses allowing multiple Spectacles to interact when sharing Wi-Fi<ref name="wikipedia"></ref>

Notable creators given early access included:
* '''Don Allen Stevenson III''' - XR Developer - Vibe Quest AR
* '''Lauren Cason''' - Creative Technologist - Taos, Caldera, and Anita
* '''Kat V. Harris''' - Technical Designer - Dance Helper
* '''Zach Lieberman''' - Artist - Poem World (with Shantell Martin)<ref name="newsroom"></ref>

==Developer Program==

Snap distributed Spectacles 4 through an application process:
* Developers could apply at the official Spectacles website
* Approximately 1,000 units planned for distribution
* No cost to selected developers
* Included support from Snap's team
* Required use of Lens Studio for development<ref name="roadtovr"></ref>

==Reception and Impact==

The announcement generated significant interest in the AR development community. Publications praised Snap for transparently showing the limited field of view in promotional materials, with Road to VR noting: "props to Snap for making an effort to show how limited the field-of-view is in its promotional materials."<ref name="roadtovr"></ref>

The glasses were seen as an important stepping stone toward consumer AR glasses, with Snap CEO Evan Spiegel demonstrating experiences like AR butterflies landing on his hand during the launch presentation.<ref name="newatlas"></ref>

==Legacy==

Spectacles 4 marked several important milestones:
* First Snap Spectacles with AR displays
* Introduction of hand tracking and spatial computing
* Establishment of Snap as a serious player in AR hardware
* Foundation for the more advanced [[Snap Spectacles 5|Spectacles 5]] and [[Snap OS]]<ref name="wikipedia"></ref>

The developer feedback and lessons learned from this generation directly influenced the significant improvements seen in Spectacles 5, including expanded field of view, better battery life, and the introduction of Snap OS.
