This HCI concept appears as part of a larger project called Smarthouse Bootcamp and evaluates the advantages regarding the development of new technologies such as keyless and electonic security mechanisms. While electronic security and locking mechanisms can be convenient, many of these types of human computer interaction designs affects and compromises security, authentication, identification, and automation. I propose a solution for optimizing the user experience and discuss the benefits for simple changes to retain the traditional appearance and basic function of doorknobs with a modern way of electronic security access.
Because the client identified a high percentage of her time is spent traveling or commuting for both personal and professional employment a voice activated door mechanism appears to be best suited for her needs as she will no longer need to carry or risk losing her house keys when on long trips. The command “Door” is for both: locking or unlocking. Whichever state the lock is in, the command “Door” will indicate the lock is to have the opposite state.View the PDF
If the lock is not engaged, using the voice command “Door,” followed by the code will make the mechanism lock . If the lock is engaged and the voice command “Door,” is said and followed by the code, then the door will unlock.View the PDF
The DLI-5000 is one possibility with some adjustments. Following the “Door” command, the cover slides upwards to reveal a dialpad. The set of circles on the bottom will be the key hole for the option to be able to have a physical house key control and override the lock mechanism in the event there is an error with the dialpad.View the PDF
A secondary alternative is to have a disappearing door knob (pictured to the right) with a keyhole. After the voice command "Door," the knob pops out; the knob has the numbers 0-9 on it, and a notch glows enough to give limited short range visibility for low light or night settings. This will function like a combination lock, though be less visible to visitors and those passing by unless the knob undergoes up-close inspection. It does not matter if the number dial is turned clockwise or counter clockwise as long as the correct numbers are entered in the correct sequence the home owner has programmed. The traditional keyhole with key could override the lock mechanism at any time.View the PDF
When the door is locked, the knob pops out when activated by voice command. The knob stays popped out until the door is unlocked or until 3 failed attempts are made.The combination to lock/unlock is entered, briefly pausing at each of the digits set by the home ownerView the PDF
