and an output unit structured to output the adjustment information, wherein the adjustment information includes information for adjusting one or more of the adjustable features. ### Claim 2 (depends on 1) The electronic apparatus of claim 1, wherein the adjustment determination unit is further configured to receive a 3-D model of the patient's head and/or neck, and wherein the adjustment determination unit is structured to further use the 3-D model of the patient's head and/or neck to calculate the adjustment information. ### Claim 3 (depends on 1) The electronic apparatus of claim 1, further comprising one or more headgear force sensors structured to measure force between headgear and a shell included in the patient interface device, wherein the adjustment determination unit is structured to receive the headgear force measurement and to further use the headgear force measurements to calculate the adjustment information. ### Claim 4 (depends on 1) The electronic apparatus of claim 1, further comprising a touch sensor mask structured to measure interaction between the patient interface device and the patient's face, wherein the adjustment determination unit is structured to receive the measured interaction and to further use the measured interaction to calculate the adjustment information. ### Claim 5 (depends on 1) The electronic apparatus of claim 1, wherein the patient interface device information includes a 3-D model of the patient's face, and wherein the adjustment determination unit analyzes the interaction between the 3-D model of the patient interface device and the 3-D model of the patient's face to calculate the adjustment information. ### Claim 6 (depends on 1) The electronic apparatus of claim 1, wherein the adjustment determination unit is structured to receive pre-calculated adjustment information for the patient interface device corresponding to other faces, and wherein the adjustment determination unit compares the patient's face with the other faces and uses the pre-calculated adjustment information for the patient interface device corresponding to the one or more other faces determined to be similar to the patient's face to calculate the adjustment information for patient interface device corresponding to the patient's face. ### Claim 7 (depends on 1) The electronic apparatus of claim 1, wherein the output unit is structured to output the adjustment information as a set of instructions for adjusting the patient interface device, and wherein one or more of the adjustable features of the patient interface device include indication markings identifying different adjustment settings. ### Claim 8 A method implemented on a computer system comprising a non-transitory computer readable medium having computer code stored thereon for adjusting a patient interface device being structured to facilitate delivery of a flow of gas to an airway of a patient and including one or more adjustable features, the method comprising: creating a 3-D model of a patient's face; providing patient interface device information for the patient interface device; calculating adjustment information for the patient interface device corresponding to the patient's face using the patient interface device information and the 3-D model of the patient's face; and outputting the adjustment information, wherein the adjustment information includes information for adjusting one or more of the adjustable features. ### Claim 9 (depends on 8) The method of claim 8, further comprising measuring the patient's head and/or neck, wherein calculating the adjustment information further uses the measurements of the patient's head and/or neck. ### Claim 10 (depends on 8) The method of claim 8, wherein the patient interface device information includes a 3-D model of the patient interface device, and wherein calculating the adjustment information includes analyzing interaction between the 3-D model of the patient interface device and the 3-D model of the patient's face. ### Claim 11 (depends on 8) The method of claim 8, further comprising receiving pre-calculated adjustment information for the patient interface device corresponding to other faces, wherein calculating the adjustment information includes comparing the patient's face with the other faces and using the pre-calculated adjustment information for the patient interface device corresponding to one or more of the other faces to calculate the adjustment information for the patient interface device corresponding to the patient's face. ### Claim 12 (depends on 8) The method of claim 8, further comprising using the adjustment information to adjust the adjustable features of the patient interface device prior to providing the patient interface device to the patient; and providing the adjusted patient interface device to the patient. ### Claim 13 (depends on 8) The method of claim 8, further comprising providing the adjustment information to the patient. ### Claim 14 (depends on 8) The method of claim 8, further comprising creating adjustable features based on the adjustment information; and providing the patient interface device including the created adjustable features to the patient.
