Why Did the First Computer Mouse Have a Wire at the Front?

💡 The Answer

• The wire at the front reduced resistance when moving the device across the desk.
• Douglas Engelbart's 1963 prototype used two perpendicular wheels to track motion.
• The wire was designed to stay out of the user's hand path, unlike modern mice with rear cables.
• Early users found the front cord less prone to tangling during operation.
• Later designs moved the cable to the back to accommodate right-handed grip and reduce visual obstruction.
