One of the limitation is the sensibility of words detecting. To ensure the pre-setting words can be detected, the sensitivity is set very low. This means words with similar pronunciation might be recognised the same. The working principle of voice recognition is based on the tones and the ending character. So that any words ending with d might cause the same interaction as the word bad. The low sensibility also limit the number of words could be recored in the system for testing. Also, context and individual accents will impact significantly on the performance of LOME. The current version can only be used at quiet environment. Another limitation is non-individual LED lights. It was assumed that petals can be taken out and place it back by plugging in or out. However, in the final product, a LED circle light was used and couldn’t be separated as individual lights. The replacement part is accomplished by voice control replace.
