After spending far too much time aimlessly wandering the aisles of Home Depot last night, I got one of those "lightbulb" ideas. Wouldn't it be a great if you had a voice-activated handheld device to easily locate what you needed? To find a smoke detector, for example, you would talk into the device, which would then say "smoke detectors are located in aisle nine". You would then walk to aisle nine and quickly complete your shopping. This "brilliant" use of technology could reduce costs because you wouldn't need as many employees on the floor, and it would improve customer service/satisfaction. To use the shopping helper device, customers would have to leave a credit card of driver's license. I figure this device would be great for any big box-retailer such as Costco, Sam's Club, Wal-Mart and Best Buy. The big obstacle would be loading the data to make the devices work but that's for IT guys to figure out.
