# One-Handed Peripherals The Twiddler3 is a One-Handed Keyboard and Mouse Hybrid By Rahul Kalvapalle | Published 2015-04-16 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/onehanded-keyboard References: [gizmag](http://www.gizmag.com/one-handed-twiddler3-keyboard-tekgear/36952/) & [twiddler.tekgear](http://twiddler.tekgear.com/index.html) The Twiddler3 is a [one-handed keyboard and mouse hybrid](https://www.trendhunter.com/trends/the-id360-touchstone) that relies on chorded movements akin to the ones made when you play a guitar. Rather than just being a miniature version of a regular keyboard, the Twiddler3 is actually designed to feel more like a joystick. It offers full access to a keyboard and mouse in one hand. The device has a fat charge and doesn't need to be recharged very often. This one-handed keyboard-mouse hybrid has four special keys -- num, alt, ctrl and shift -- which are controlled by the user's thumb. The other four fingers control [three mouse buttons](https://www.trendhunter.com/trends/computer-mouse-concept) and 12 other buttons used to type. The Twiddler3 is certainly a device that poses a steep learning curve, but the ability to get your work done while still having one free hand is certainly alluring. ## Trend Insights (Trend Hunter) - Score: 1.7/10 - Popularity: 28% | Activity: 15% | Freshness: 8% - Audience gender: 70% men, 30% women - Primary generations: Gen Z, Millennial, Gen X - Top markets: North America, Europe, Asia ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Tech](https://www.trendhunter.com/tech) > [Gadgets](https://www.trendhunter.com/gadgets) ## Key Themes ### What's Driving This Trend - **One-handed Peripherals:** The trend of developing one-handed peripherals, like the Twiddler3, offers disruptive innovation opportunities for individuals with limited mobility or those seeking increased productivity on the go. - **Chorded Input Devices:** The trend of chorded input devices, such as the Twiddler3, presents disruptive innovation opportunities for wearable technology and human-computer interaction. - **Hybrid Keyboard-mouse Devices:** The trend of hybrid keyboard-mouse devices like the Twiddler3 creates disruptive innovation opportunities for compact and ergonomic input solutions for mobile professionals. ### Who This Affects Most - **Accessibility Technology:** The accessibility technology industry can leverage one-handed peripherals like the Twiddler3 to create innovative solutions for individuals with disabilities. - **Wearable Technology:** The wearable technology industry can explore chorded input devices like the Twiddler3 to develop hands-free and intuitive control interfaces for smart devices. - **Mobile Computing:** The mobile computing industry can capitalize on hybrid keyboard-mouse devices like the Twiddler3 to improve productivity and user experience for on-the-go professionals. ## Related on Trend Hunter - [One-Handed Gamer Keyboards](https://www.trendhunter.com/trends/mechanical-gaming-keypad.md) - [Wearable PC Keyboard Controllers](https://www.trendhunter.com/trends/grab-shell.md) - [Glove-Like Keyboard Peripherals](https://www.trendhunter.com/trends/glove80-keyboard.md) - [Gesture Control Keyboards](https://www.trendhunter.com/trends/clvx-1-keyboard.md) - [Typing Speed-Increasing Devices](https://www.trendhunter.com/trends/charachorder-x.md) - [Sleek Wireless Split Keyboards](https://www.trendhunter.com/trends/wing45.md) - [Intuitive Gesture-Control Mouses](https://www.trendhunter.com/trends/tactigon-skin-wearable-mouse.md) - [Remote Presentation Mouses](https://www.trendhunter.com/trends/wearable-finger-mouse.md) - [Single-Handed Gaming Controllers](https://www.trendhunter.com/trends/onehanded-dualsense-controller.md)
