Smartwatches have come a long way over the last few decades. From simple calculator watches in the 1970s and 80s to today's do-it-all wrist companions, the evolution of the smartwatch has been driven by major advancements in technology. Let's explore where smartwatches began, how they've progressed, and where they might be headed next.
The Beginning - Calculator Watches
In the 1970s and 1980s, one of the first consumer gadgets that could be considered an early smartwatch was the calculator watch. These digital watches integrated basic calculators into the watch face, allowing users to perform simple mathematical equations right on their wrist. Though limited in function, calculator watches represented an important step towards miniaturizing computer technology to wearable formats. However, they were still very limited in utility compared to the multi-functional smartwatches of today.
"The calculator watch was one of the earliest wearable technologies to provide useful functionality beyond simple timekeeping."
Pager Watches Gain Popularity
As mobile phones were still bulky and expensive in the 1980s and 90s, pager watches became a popular way to receive notifications on the go. These watches connected to pager networks to allow wearers to receive numeric messages. Users could also send simple pre-written messages back by navigating small menus on the tiny watch screens. Though reading full messages on these watches wasn't feasible, they were useful for alerting users quickly when they needed to find a landline to return an important page.
Early Smartwatches - Connected to Phones
In the 1990s and 2000s, innovations in mobile technology paved the way for early smartwatches that could connect to phones via Bluetooth. These let users do things like view call ID and notifications, control music playback, and more directly from the watch. The palmOne Zire 72 in 2004 and the Linux-based WIMM One watch in 2011 were some early examples of connected watches. This generation showed the possibilities of modern smartwatches paired with smartphones. However, early limitations in battery life, display quality, processing power and connectivity prevented widespread consumer adoption.
Full Touchscreen Smartwatches Emerge
The release of the first full touchscreen smartwatches marked a major leap forward in capabilities and popularity. Devices like the Pebble in 2013, Samsung Galaxy Gear in 2013, and Apple Watch in 2015 made smartwatches highly customizable and able to run feature-rich apps. Touchscreens and improved processors allowed for intuitive user interfaces, while Bluetooth and WiFi enabled robust two-way communication with smartphones. Health and fitness tracking also became mainstream smartwatch features during this period, making them useful day-to-day tools.
Smartwatches Become Mainstream
While early smartwatches were mostly niche products, by the mid-2010s they broke through to the mainstream consumer market. Devices like the Apple Watch and Fitbit became some of the top consumer electronics products by revenue. The watchOS and Wear OS platforms further drove software development and app creation tailored to smartwatches. With their combination of style, utility and health tracking, smartwatches are now integral accessories for many tech users rather than just novel gadgets. Their evolution has been truly remarkable.
Features that Define Modern Smartwatches
Today, smartwatches are designed to be highly capable personal assistants and health/fitness tools right on your wrist. Here are some of the most important features that define modern smartwatches:
Health and Fitness Tracking
One of the signature functions of smartwatches is their ability to track key health and fitness metrics 24/7. They provide both general activity tracking as well as detailed workout analysis.
Heart Rate Monitoring
Most smartwatches contain optical heart rate sensors on the backside. This allows them to take background heart rate readings throughout the day and provide finely detailed heart rate data during exercise sessions. Tracking heart health and workouts without chest straps makes smartwatches highly convenient fitness tools.
Step Counting and Activity Tracking
Smartwatches use an accelerometer and gyroscope to automatically count your steps taken, distance covered, and calories burned. Sophisticated sensors can also track specific exercises like swimming and elliptical training. Seeing your daily activity at a glance helps motivate users to stay active and healthy.
Notifications and Alerts
With Bluetooth connectivity to your smartphone, the ability to discretely view notifications is another signature smartwatch function.
Emails, Texts, and Calls
Get notifications from your smartphone apps sent straight to your wrist. Smartwatches let you triage and quickly respond to important emails, texts, calls without pulling out your phone.
Calendar and Reminder Alerts
Stay on schedule with alerts about upcoming meetings and other calendar events. Smartwatch reminders also provide prompts for tasks, medications, and other important information.
Media Controls and Connectivity
In addition to health tracking and notifications, media controls and wireless connectivity make modern smartwatches incredibly convenient:
Music and Podcast Controls
Control your smartphone music library from your watch to easily play, pause, skip tracks without reaching for your phone. Volume controls are also handy for quick audio adjustments.
Bluetooth and WiFi Connectivity
Bluetooth allows smartwatches to pair with smartphones and wireless headphones. WiFi connectivity enables standalone smartwatch functions like streaming, app usage, and updates when out of Bluetooth range.
The Leading Smartwatch Platforms
The smartwatch landscape is currently dominated by three major platforms: Apple Watch, Wear OS, and Samsung's Tizen OS. Here's an overview of the leading options:
Apple Watch
The Apple Watch exemplifies deep integration between hardware, software, and services using watchOS.
Sleek Design and Intuitive UI
Apple's trademark minimalist design and intuitive user interface make the Apple Watch aesthetically and functionally appealing. The Digital Crown provides fluid scrolling and navigation.
Deep iOS Integration
Seamless pairing and integration with iPhones allows Apple Watch to most effectively leverage notifications, iMessage, Apple Pay, Apple Music, and more for iOS users.
Wear OS
Originally Android Wear, Wear OS is designed to be the smartwatch platform for Android phones.
Integration with Android Phones
Wear OS integrates tightly with Android notifications, Google services like Google Pay, and the Google Play app ecosystem. This makes it versatile for most Android users.
Google Assistant Capabilities
With the Google Assistant built-in, Wear OS watches allow you to use voice commands for queries, reminders, and more. Useful hands-free functionality.
Samsung's Tizen OS
Samsung uses its own Tizen operating system optimized for Galaxy smartphones and tablets.
Rotating Bezel Navigation
The rotating bezel enables easy scrolling through Tizen OS menus and provides an intuitive hardware control method.
Samsung Health Tracking
Deep integration with Samsung Health gives users detailed wellness tracking tied into the wider Samsung ecosystem.
The Future of Smartwatches
As smartwatches become more advanced and gain adoption, we can expect to see key improvements in health tracking, battery life, and connectivity:
Advancements in Health Monitoring
More advanced biosensors will enable smartwatches to provide deeper health insights:
Blood Pressure and Glucose Tracking
Built-in sensors will allow on-demand blood pressure and blood glucose measurements for users with conditions like diabetes.
ECG and Fall Detection
ECG sensors can help identify arrhythmias, while fall detection could automatically alert emergency contacts if a hard fall is detected.
Extended Battery Life
For a better overall user experience, smartwatches will need to maximize battery life:
