In one embodiment, an automated system for cutting hair on a subject comprises a hair cutting device, configured for manual manipulation, the hair cutting device comprising a cutting mechanism and configured to engage the cutting mechanism to cut said hair. The automated system interacts with the hair cutting device for determining a position of the hair cutting device relative to the subject. ## Claims ### Claim 1 An automated system for cutting hair on a subject, comprising: a hair cutting device, configured for manual manipulation, comprising a cutting mechanism and configured to engage said cutting mechanism to cut said hair; a positioning device coupled to said subject, the positioning device comprising at least one positioning interface; and a sensor hub, the sensor hub configured to interact through signals with the hair cutting device and the positioning device for determining the position of the hair cutting device relative to the subject. ### Claim 2 (depends on 1) The system as recited in claim 1, wherein said sensor hub is configured to generate at least a subset of said signals and at least one of said positioning device and said hair cutting device are configured to receive said at least a subset of said signals. ### Claim 3 (depends on 1) The system as recited in claim 1, wherein said hair cutting device is configured to generate at least a subset of said signals and at least one of said positioning device and said sensor hub are configured to receive said at least a subset of said signals. ### Claim 4 (depends on 1) The system as recited in claim 1, wherein said positioning device is configured to generate at least a subset of said signals and at least one of said sensor hub and said hair cutting device are configured to receive said at least a subset of said signals. ### Claim 5 (depends on 1) The system as recited in claim 1, wherein said signals comprise at least one of optical signals, light signals, structured light signals, radar signals, infrared signals, sound signals, ultrasonic signals, sonar signals, radio signals, electromagnetic signals, or visible features that may be observed with a camera. ### Claim 6 (depends on 1) The system as recited in claim 1, wherein the system is further calibrated by articulating said hair cutting device about a plurality of physical features of said subject. ### Claim 7 An automated system for cutting hair on a subject, comprising: a hair cutting device, configured for manual manipulation, comprising a cutting mechanism and configured to engage said cutting mechanism to cut said hair; a positioning device coupled to said subject, the positioning device comprising at least one positioning interface; and a camera, the camera generating at least one image, said image employable for at least partially determining the position of the hair cutting device relative to the subject. ### Claim 8 (depends on 7) The system as recited in claim 7, wherein said camera is mounted on said hair cutting device. ### Claim 9 (depends on 7) The system as recited in claim 7, wherein said camera is mounted on said positioning device. ### Claim 10 (depends on 7) The system as recited in claim 7, wherein said camera is mounted on a sensor hub. ### Claim 11 (depends on 7) The system as recited in claim 7, wherein said camera is mounted on a computing device. ### Claim 12 (depends on 11) The system as recited in claim 11, wherein said computing device comprises a cell phone, tablet computer, notebook computer, or desktop computer. ### Claim 13 (depends on 7) The system as recited in claim 7, wherein the system further comprises an illumination source. ### Claim 14 (depends on 13) The system as recited in claim 13, wherein the illumination source is employable to generate structured light. ### Claim 15 (depends on 7) The system as recited in claim 7, wherein said positioning interface comprises at least one visible object that is recognizable in a camera image. ### Claim 16 A computing device configured to communicate a control signal for at least partially controlling a cutting mechanism, the cutting mechanism controllable to cut hair on a subject, the computing device comprising: a camera, the camera generating at least one image under illumination with structured light, and wherein said at least one image under illumination with structured light is employable for at least partially determining the position of the cutting mechanism relative to the subject, and wherein said control signal is at least partially responsive to the determined position of the cutting mechanism relative to the subject; an acoustic transducer capable of producing an audible sound; an electronic display capable of producing a visible indication; and an electronic interface capable of communicating an electronic message; wherein said control signal is communicated by the computing device through at least one of said acoustic transducer, said electronic display, or said electronic interface. ### Claim 17 (depends on 16) The computing device as recited in claim 16, wherein said computing device is further configured so that a person may receive said control signal and manually control said cutting mechanism at least partially responsive to said control signal. ### Claim 18 (depends on 16) The computing device as recited in claim 16, wherein said computing device is further configured so that an apparatus may receive said control signal and automatically control said cutting mechanism at least partially responsive to said control signal. ### Claim 19 (depends on 16) The computing device as recited in claim 16, wherein said computing device further comprises an indicator light capable of producing a visible light and said control signal is communicated by the computing device through said indicator light. ### Claim 20 (depends on 16) The computing device as recited in claim 16, wherein said electronic interface interacts with an electromagnetic wave that propagates wirelessly.
