The device includes a housing. A light source is affixed in or on the housing. The light source generates light during at least a portion of the gaze field sobriety test. A speaker positioned in or on the housing generates sounds during at least a portion of the gaze field sobriety test. A power source is coupled to the speaker and the light source. An input is positioned on the housing. The input is selectable by a test administrator to initiate an audible sound through the speaker at a predetermined time interval during at least a portion of the gaze field sobriety test. The audible sound provides an indication to the test administrator during the gaze field sobriety test to assist in proper performance of the gaze field sobriety test. ## Claims ### Claim 1 A method, the method comprising: causing a handheld computing device to perform providing a visual target on a handheld computing device, wherein the visual target is provided during at least a portion of a gaze nystagmus test; and generating at least one test administrator signal from the handheld computing device, wherein the at least one test administrator signal provides an indication to the test administrator regarding movement of the handheld device during the gaze nystagmus test to assist in proper performance of the gaze nystagmus test. ### Claim 2 (depends on 1) The method of claim 1, wherein: the providing a visual target on a handheld computing device further comprises activating a light source. ### Claim 3 (depends on 1) The method of claim 1, wherein: the generating at least one test administrator signal from the handheld computing device further comprises generating at least one test administrator signal from the handheld computing device in response to an actuation of a first input on the handheld computing device by a test administrator. ### Claim 4 (depends on 1) The method of claim 1, further comprising: recording movements of the handheld computing device during the gaze nystagmus test using a motion sensor within the handheld computing device. ### Claim 5 (depends on 1) The method of claim 1, wherein the generating at least one test administrator signal from the handheld computing device comprises generating audible sound through a speaker of the handheld computing device. ### Claim 6 (depends on 1) The method of claim 1, further comprising: recording a video of eye movements of a test subject using a camera of the handheld computing device during the gaze nystagmus test. ### Claim 7 A system, comprising: at least one processor; and a memory comprising program instructions, wherein the program instructions are executable by the at least one processor to: provide a visual target on a handheld computing device, wherein the visual target is provided during at least a portion of a gaze nystagmus test; and generate at least one test administrator signal from the handheld computing device, wherein the at least one test administrator signal provides an indication to the test administrator regarding movement of the handheld device during the gaze nystagmus test to assist in proper performance of the gaze nystagmus test. ### Claim 8 (depends on 7) The system of claim 7, wherein: the program instructions executable by the at least one processor to provide a visual target on a handheld computing device further comprise the program instructions are executable by the at least one processor to activate a light source. ### Claim 9 (depends on 7) The system of claim 7, wherein: the program instructions executable by the at least one processor to generate at least one test administrator signal from the handheld computing device further comprise program instructions executable by the at least one processor to generate at least one test administrator signal from the handheld computing device in response to an actuation of a first input on the handheld computing device by a test administrator. ### Claim 10 (depends on 7) The system of claim 7, further comprising: program instructions executable by the at least one processor to record movements of the handheld computing device during the gaze nystagmus test using a motion sensor within the handheld computing device. ### Claim 11 (depends on 7) The system of claim 7, wherein the program instructions executable by the at least one processor to generate at least one test administrator signal from the handheld computing device comprise program instructions executable by the at least one processor to generate audible sound through a speaker of the handheld computing device. ### Claim 12 (depends on 7) The system of claim 7, further comprising: program instructions executable by the at least one processor to record a video of eye movements of a test subject using a camera of the handheld computing device during the gaze nystagmus test. ### Claim 13 A non-transitory computer-readable storage medium storing program instructions, wherein the program instructions are computer-executable to implement: providing a visual target on a handheld computing device, wherein the visual target is provided during at least a portion of a gaze nystagmus test; and generating at least one test administrator signal from the handheld computing device, wherein the at least one test administrator signal provides an indication to the test administrator regarding movement of the handheld device during the gaze nystagmus test to assist in proper performance of the gaze nystagmus test. ### Claim 14 (depends on 13) The non-transitory computer-readable storage medium of claim 13, wherein: the program instructions computer-executable to implement providing a visual target on a handheld computing device further comprise program instructions computer-executable to implement activating a light source. ### Claim 15 (depends on 13) The non-transitory computer-readable storage medium of claim 13, wherein: the program instructions computer-executable to implement generating at least one test administrator signal from the handheld computing device further comprise program instructions computer-executable to implement generating at least one test administrator signal from the handheld computing device in response to an actuation of a first input on the handheld computing device by a test administrator. ### Claim 16 (depends on 13) The non-transitory computer-readable storage medium of claim 13, further comprising: program instructions computer-executable to implement recording movements of the handheld computing device during the gaze nystagmus test using a motion sensor within the handheld computing device. ### Claim 17 (depends on 13) The non-transitory computer-readable storage medium of claim 13, wherein the program instructions computer-executable to implement generating at least one test administrator signal from the handheld computing device comprise program instructions computer-executable to implement generating audible sound through a speaker of the handheld computing device. ### Claim 18 (depends on 13) The non-transitory computer-readable storage medium of claim 13, further comprising: program instructions computer-executable to implement recording a video of eye movements of a test subject using a camera of the handheld computing device during the gaze nystagmus test.
