Wearable Computers vs. Handheld Devices: Which Is Better for Workflow Efficiency?
Posted on
When you’re looking for the best way to capture barcode data in warehouses, distribution centers, and manufacturing facilities, you have two main choices: wearable computers and handheld devices.
Both can help workers capture data accurately and access important information, but there are a few key differences between the two. A wearable computer keeps technology accessible and allows workers to use both hands for other tasks, while handheld devices typically offer larger displays and more capabilities for tasks that require frequent interaction with software.
So, which is better for workflow efficiency? The answer depends on how your employees work, how often they scan, and how much interaction each task requires.
Wearable Computer vs. Handheld Device: What’s the Difference?
A wearable computer is a compact mobile computing or data-capture device designed to be worn on the wrist, hand, finger, or another part of the body rather than carried in the hand. Wearable technology can include barcode scanners, RFID readers, wearable mobile computers, and ring scanners.
Handheld devices are mobile computers or scanners that workers carry and operate by hand, allowing them to scan items and interact directly with the software. They typically combine a scanner with a screen and operating system.
The biggest difference between the two is how workers interact with the technology.
1. Hands-Free Operation: A wearable computer can reduce the need to hold or repeatedly pick up a device, which can help streamline high-volume picking, sorting, packing, and replenishment workflows where employees are constantly moving items.
2. Workflow Speed: Wearable computers can make repetitive workflows more efficient by reducing unnecessary movement between scanning and handling items. Rather than reaching for and repeatedly repositioning a device, workers can scan products while keeping their hands focused on the task.
3. Access to Information: Handheld mobile computers may be the better choice when workers need to spend more time viewing information or interacting with the device rather than simply scanning. Their larger screens make it easier to review product details, navigate menus, enter information, and complete more complicated transactions.
Which is the Better Choice?
While every situation is different, here’s where wearable computers and handheld computers are the better choice.
Choose wearable computers when: The workflow involves frequent scanning, repetitive movements, and hands-on product handling, such as high-volume order picking, inventory and cycle counting, packing and sorting, manufacturing, and RFID applications.
Choose handheld devices when: Employees need to interact with the technology, as with complex data entry, infrequent scanning, detailed inspections, and environments with multiple applications.
Can You Use Both?
Choosing between a wearable computer and a handheld device does not have to be an either/or decision. For many companies, a hybrid approach may be the best option, with wearable scanners for high-volume picking and handheld mobile computers for receiving, returns, inspections, or other tasks that require more screen interaction.
How to Choose the Right Device for Your Workflow
Before choosing a wearable computer or handheld device, consider the following factors.
- Workflow: Identify how often employees scan, how frequently they handle products, and whether their hands need to remain free.
- Amount of data entry: Wearable technology may be perfect for simple scan-and-go processes, while more complex transactions may be better suited to handheld devices.
- Device integration: Make sure the device works with your warehouse management system, enterprise software, and any other systems used by your operation.
- Environment: Temperature, dust, moisture, drops, and other environmental conditions can affect device selection. Choose hardware designed for the conditions in which it will be used.
- Employee comfort. Employees are more likely to use technology effectively when it is comfortable and intuitive. Don’t rely on product demonstrations: test devices with real users in actual working conditions to identify any issues.
- Cost of ownership: The cost of a device is only one aspect of the overall investment. Factor in accessories, batteries, charging equipment, maintenance, support, software, and the potential productivity gains associated with the technology.
When evaluating wearable computers vs. handheld devices, it’s important to remember that there is no universal right answer. By considering factors such as scanning frequency, task complexity, and how much workers need to interact with their devices, businesses can decide whether wearable computers, handheld devices, or a hybrid approach is the best choice.
