Preliminary Test Plan
MSD P11032 Preliminary Test Plan
For a presenter who is communicating with an audience using ASL, the act of pausing to advance or go back in a presentation interrupts the flow of information to the audience. The presenter must stop signing to use his or her hands to manually adjust the presentation. An alternative to this would be a wireless device which allowed the presenter to advance to the next slide or previous slide without interfering with signing. Our goal is to provide the deaf community with a "proof-of-concept" solutions which meets all customer requirements.
User Test Multiple specifications will be verified by a user test. This test will be performed using a range of users, but the ultimate decision regarding Pass/Fail will be determined by a user test performed by principal customer Gary Behm. More detailed test procedures will be developed at a later date.
- Windows PC with Microsoft PowerPoint 2003 or later
- Digital Scale
- PC-Connected Projector
- Projector Screen
- Digital Multimeter
- PC Stopwatch Program
- 3DSSPP Software
1. Device will be under 0.5 pound(s). The complete device (including the band) will be weighted on a digital scale with .01 accuracy. The device must weigh less than 0.5 lb.
2. Device will allow full range of natural motion, including excessive hand motion and roaming the presentation area. (No wires or restrictive components) The wristband device will be worn an ASL user and who will be asked to sign for a minute (a prewritten document) while walking back and forth through the classroom.
3. Maximum Size will be less than 24 cubic inches. The casing from the device will be measured by calipers in length, width, and height. The volume of the device has be less than 24 cubic inches. (excluding the band)
4. Device can sustain multiple drops from waist height (~3ft) onto carpeted surface. There will be 3 steps to passing this criteria. First the device will be tested on a computer to show that it is working. Second the device will be dropped 10 times from 3ft on the carpeted floor in Erdle Commons. The device will be released from the hand to replicate accidental drop. Third, the device must work after the 10 drops and will be verified by testing it on a computer.
5. Device will allow ASL to be utilized without major interference. A 2 minute presentation will be given using ASL by a test subject. Based on their response, a pass or fail criteria will be given. (Gary will gives us feedback since he is the customer) (Will be part of test 2)
6. Device will not progress to next slide, or return to previous slide, without intentional activation. 10 users have to have an 80% success rate of reaching the targeted slide.
7. Device will work within a range of minimum of 40 feet from PC without problem. A computer will be place 30ft away from the device. The device must be able to flawlessly scroll a 20 slide presentation to the end and then back.
8. Device will be implemented for minimum cost. The cost of the project will be less then the allowed budget of $750.
9. Battery life will exceed 4 hours of continual usage. Put in a new battery. Set up a laptop. Press the up button and leave it on for four hours. The remote must work after four hours. Pass/Fail
10. Latency between button push and slide change will be less than 0.75s Create a powerpoint with 100 numbered slides. Starting at slide #1, the tester will press the next slide button as rapidly as possible. After 60 seconds, the user must reach at least slide #80. By surpassing slide #80 in 60 seconds, the tester will have achieved an average slide change time of .75 seconds or less.
11. Device successfully advances to next and previous slides. The wristband will be used to flip 20 slides to the end and then back at 10 ft away without any trouble. This test will be covered by test 7.
12. The device will be safe to use for as wide of the population as possible. A model will be created in the 3DSSPP software to show that the device does not pose any dangers to joints and muscles.
